MIDDLE GROUND

How Manufacturing Pros Can Lead Even Without Formal Authority

Issue 065

You don’t sign the POs. You don’t approve the final drawings. You’re not the one in the executive review when timelines shift.

But when the supplier misses their target—or tolerances don’t hold in production—you’re still the one expected to fix it.

That’s the reality for many engineers, sourcing leads, and operations pros: you live in the middle—responsible for outcomes, but not always in control of decisions.

⚙️ The Problem: You're Accountable Without Authority

In real-world stamping programs, the folks closest to the risk—engineers, buyers, leads—are often furthest from decision-making power.

🧩 Design might move forward without supplier feedback
💸 Sourcing might award a job based on unit price—not die complexity
🚨 Production might get pulled in after the print is locked

And through it all, you’re expected to make it all work.

🧭 The Fix: Lead With Insight, Not Title

You don’t need a title to lead. What you need is clarity, timing, and trust—especially in tooling-heavy environments where supplier collaboration makes or breaks a launch.

Here’s how professionals are guiding decisions from the middle—with tools and supplier-backed insight.


✅ 1. 📊 Use Vendor Data to Strengthen Your Case

Skip the debate—bring the data.

🧾 Many experienced tooling suppliers provide:

  • 📐 Tooling feasibility guides — to flag risk in tolerances, bend reliefs, or edge distances

  • 📉 Preliminary strip layout visuals — to catch part orientation, feed direction, or scrap concerns

  • 🏷️ Material risk indicators — for DFARS/ROHS compliance, long-lead alloys, or plating restrictions

By presenting this data upstream, you’re not making demands—you’re showing the path.


📋 2. 🔦 Make Risk Visible With Upstream Tools

The earlier a problem is seen, the cheaper it is to fix.

🧰 Leading teams use:

  • 🚩 RFQ “watch-out” lists — to highlight DFM flags or tolerance traps

  • 📅 Part readiness trackers — to keep sourcing, engineering, and production on one cadence

  • Pre-launch checklists — based on APQP or PPAP-lite frameworks that map risk across roles

This kind of visibility earns you respect—not because you shout louder, but because you see clearer.


🤝 3. 🧠 Build Trust Through Supplier Collaboration

Strong suppliers aren’t just vendors—they’re your early warning system.

When you bring in a progressive die partner early, they help you:

  • Catch tolerance mismatches before quoting

  • Estimate realistic tooling timelines

  • Flag in-die feasibility issues before anyone else sees them

That insight gives you leverage—not to control decisions, but to guide them constructively.

🚀 The Outcome: Influence Without a Title

When you lead this way, even without a formal role, things change:

📉 Fewer late-stage change orders
🎯 More accurate supplier timelines
🙌 Better cross-functional trust

And you? You become the person who drives clarity across the noise. The one people go to before things go sideways.

Feeling like you carry the risk but not the authority?

DEADLINE PUSHBACK

How to Challenge Unrealistic Manufacturing Timelines (Without Sounding Difficult)

Issue 064

If you’ve ever stared at a launch timeline and thought, There’s no way this is happening, you’re not alone.

A project manager promises the customer a delivery date. It’s aggressive. You know raw material is weeks out, the CAD isn’t final, and the supplier hasn’t even quoted tooling. But saying “this won’t work” can make you look like the bottleneck.

Welcome to modern manufacturing!

🚦 The Problem: When Ambitious Schedules Ignore Physics

In precision stamping programs, delays rarely happen because of laziness or lack of effort. They happen because the plan wasn’t grounded in the realities of:

  • • Tool complexity and build cycle (8–14 weeks for standard dies, 16+ for complex assemblies)

  • • Material procurement, especially DFARS-compliant or high-temp alloys (often 10–12+ weeks)

  • • Cross-vendor coordination for plating, insert molding, or heat treating

And in 2025, these timelines are still impacted by supply chain volatility, material market shifts, and vendor capacity constraints.

Yet somehow, deadlines still get locked before specs are finalized. So what do you do?

🧰 The Fix: Push Back With Clarity, Not Conflict

Pushing back on a deadline isn’t a career risk—it’s a skill. But it takes the right framing.

Here’s how successful engineers and sourcing pros challenge the plan while keeping the room on their side.


✅ 1. Translate the Deadline Into Its Dependencies

Don’t say: “We can’t hit that date.”
Say:

“To meet that date, we’d need material ordered by Friday and die design frozen by Tuesday. Otherwise, we’ll miss our supplier’s tooling window.”

This reframes the deadline as a set of trade-offs—not just a denial.


📊 2. Bring Vendor Feedback Into the Room

The smartest teams don’t push back alone—they bring their suppliers into the conversation.

In early RFQ stages, some progressive die suppliers will share:

  • • Conceptual strip layouts that flag risk before steel is cut

  • • Feasibility feedback on features, material usage, or forming constraints

  • • Schedule-driven prototyping options—short-run tooling used to validate geometry while full dies are built

Use this input to ground your schedule pushback in real-world feasibility, not just internal resistance.


🔄 3. Offer Trade-Offs—Not Stone Walls

Leaders don’t want barriers. They want choices.

Try this:

“If we skip plating on the first run and use soft tooling, we can ship something in 6 weeks. For full production quality, we’d need an extra three.”

This gives your internal team or customer control—while giving you breathing room to build it right.

🎯 What Happens When You Do This Well

When cross-functional teams speak with one voice—backed by data and supplier input—deadlines shift from stress-inducing to strategic.

  • • Change orders go down

  • • Supplier engagement improves

  • • Trust across departments grows

  • • Launches don’t just happen—they land right

And you? You become the calm in the chaos. The one who knew what it would take—and made it happen.

Ever been caught in a “we-need-it-next-week” meeting?

I’d love to hear how you’ve handled the pressure—and what tools or partners made the difference.

From CAD to Reality

The 5 DFM Pitfalls That Cost Time and Money

Issue 060

A beautiful CAD model is a thing of pride. Every line intentional. Every feature defined. But here’s the truth every product engineer learns: a flawless CAD model doesn’t guarantee a manufacturable part.

If you’ve ever had a design come back from tooling with a “We can’t build this as drawn” email, you know the pain. Even experienced engineers fall into subtle design-for-manufacturability (DFM) traps—features that look fine on a screen but run headfirst into the realities of material behavior, tooling limits, or press capabilities.

Your job isn’t just to design a part—it’s to design something that works on the shop floor. As your guide, here are the five most common DFM pitfalls in metal stamping—and how to catch them before they cost you.

🎯 DFM Pitfall #1: Features Placed Across a Bend Line

It’s an easy miss in 3D: a slot, hole, or notch ending up right in the bend zone. But features placed too close—or across—a bend line can distort, crack, or even render the part unbuildable.

The Fix:
Move critical features away from bends, or plan for pre-punching with secondary forming. If unavoidable, consult tooling engineers about expected deformation or tolerance tradeoffs.

(Bonus tip: Many shops today use CAD-integrated DFM software that automatically flags features crossing bend lines—use it early!)

🎯 DFM Pitfall #2: Ignoring Grain Direction

Sheet metal has a grain—and that grain affects how the material bends and behaves. Designing bends against the grain increases cracking risk, springback, and variation, especially in high-strength steels.

The Fix:
Specify preferred grain direction in prints or work with suppliers to align coil sourcing. Need to bend across the grain? Expect higher bend radii or the need for pre-heat treatment. Modern bend simulation tools (like AutoForm or PAM-STAMP) can also predict problem zones before tooling.

🎯 DFM Pitfall #3: Over-Tightening Hole Tolerances

A ±0.001” hole might seem like a safe spec, but in stamping? That could push you into secondary drilling or reaming, adding cost and complexity. Typical stamped hole tolerances range from ±0.003” to ±0.005” in mild steel, but harder alloys or thinner gauges may need looser specs.

✅ The Fix:
Ask: does this hole really need tight tolerance? If it’s clearance or non-critical, relax specs to what stamping holds. For tighter needs, plan for secondary machining upfront.

🎯 DFM Pitfall #4: Sharp Inside Corners

That crisp 90-degree inside corner looks clean on a CAD model. But in stamping, sharp corners stress tools and parts, creating early cracking or punch wear.

✅ The Fix:
Design inside radii at least 1x material thickness (or more for harder alloys). This improves material flow, extends tool life, and reduces stress risers. Many CAD-integrated DFM tools flag undersized radii—turn them on during design reviews.

🎯 DFM Pitfall #5: Forgetting About Springback

Formed parts never bend exactly to die angles. Springback happens. Ignoring it leads to out-of-spec parts that fail assembly fits—especially in HSLA or stainless.

The Fix:
Collaborate with tooling engineers to compensate bends at die design. Many shops use forming simulation and even in-die measurement sensors in 2025 to tune forming angles dynamically.

🛠️ The Plan: Catch Issues Early, Before Steel is Cut

The best time to fix a design isn’t after the die is built—it’s before. Share CAD with your manufacturing partner early. Use DFM reviews, automated manufacturability checks, and supplier collaboration to catch problems in the digital stage.

Every change you make before tooling saves exponentially compared to fixing problems in production.

Want a second set of eyes on your next stamping design?

Let’s start a conversation. A quick DFM check could save thousands in rework and weeks in delivery.

Material Matchmaking

Choosing the Right Alloy for Function, Cost & Compliance

Issue 057

When you’re designing a critical stamped part, material choice isn’t just a box to check—it’s the heart of your product’s performance.

And let’s be real: with so many alloys competing for your attention (each offering some mix of strength, conductivity, or price), the risk of picking the wrong one is real. A poor material choice can lead to costly redesigns, compliance surprises, or worse—failure in the field.

You’re the hero here. Your design choices shape how the product performs, how it’s made, and how it meets today’s tough regulations. I’ll be your guide to the most popular stamping alloys used today, so you can match materials to performance, production, and compliance goals with confidence.

Let’s dive in.

Production Ready

How to Create Metal Stamped Parts That Actually Work in Production

Issue 054

As a product design engineer, you’ve likely felt that sinking feeling when late-stage issues unexpectedly pop up. Imagine dedicating weeks to perfect your CAD design, only to discover your metal stamped parts fail at tooling trials—uneven bends, cracked edges, or unpredictable material behaviors. If this scenario sounds painfully familiar, you’re certainly not alone.

These setbacks usually stem from overlooking essential manufacturability details during design. Thankfully, adopting practical Design for Manufacturability (DFM) strategies helps you sidestep costly production surprises.

Here are key, industry-proven DFM techniques to ensure your metal stamped parts move smoothly from your computer to the production floor.

Mind the Bend Reliefs

  • Think of bend reliefs like hinges on your door—they help parts flex without breaking. In stamping, insufficient bend relief quickly leads to cracks or tears.

    Current industry standards recommend bend reliefs equal to or greater than material thickness. While simple, designers frequently overlook this crucial detail. Including sufficient bend relief in your CAD designs greatly reduces risks during production.

Clarify Pierce-to-Edge Distances

Imagine drilling a hole too close to the edge of a wooden plank—too close, and it splinters easily. Metals behave similarly. The general guideline is maintaining a pierce-to-edge distance of at least 1.5 times the material thickness.

However, exact requirements might vary depending on material type and tooling specifics. Always reference your material guidelines or run preliminary simulations to confirm appropriate distances, ensuring structural integrity remains uncompromised.

Maintain Uniform Wall Sections

Uneven wall thicknesses may seem minor in CAD but can cause major problems during stamping. Variations result in unpredictable material flow and uneven stress distribution, leading to defects and waste.

Maintaining consistent wall thicknesses leads to predictable outcomes, helping everyone from toolmakers to stamping operators—and ultimately saves time and money.

Leverage Modern Tooling Simulations

Today’s manufacturers use advanced simulation tools and digital twins to visualize and optimize progressive die operations effectively. 

These technologies help anticipate real-world tooling challenges, identify potential issues early, and simplify your designs. Streamlined tooling cuts costs, boosts reliability, and ensures your part is both practical and economical.

Real-World Example

Consider an automotive connector bracket initially designed without proper bend relief or optimized pierce-to-edge spacing. Predictably, early prototypes suffered deformation during stamping trials. 

By implementing basic DFM revisions—adjusting bend reliefs, improving edge spacing, and utilizing digital simulation—the issues were resolved. Final stamped parts consistently exceeded quality expectations, significantly cutting production timelines.

Putting DFM Into Action

Applying these practical DFM principles transforms you from a reactive designer to a proactive manufacturing partner. You become the hero who spots potential production pitfalls early, turning designs into manufacturing successes.

Remember these strategies for your next metal stamped component:

🔧 Sufficient bend relief

📏 Optimized pierce-to-edge distances

📐 Consistent wall thicknesses

🖥️ Strategic use of modern tooling simulations

Embedding these fundamentals into your workflow ensures smooth transitions from CAD designs to finished products.

Build Better

How To Build Better Parts by Syncing Design with Manufacturing Early

Issue 051

You’ve built a solid model. Every feature is in the right place. The part fits the system. But the second it hits production, things get bumpy — tooling challenges, tolerance conflicts, or an unexpected need for a workaround. Sound familiar?

That’s where Design for Manufacturability (DFM) comes in. Done right, it’s not about dialing back your creativity — it’s about translating smart ideas into scalable outcomes.

The Problem: Perfect in CAD, Painful in Production

  • On screen, it looks great. But on the floor, a different story plays out:

  • 🌀 Deep forms call for costly multi-stage tooling

  • 📏 Tight tolerances require extra inspection or post-processing

  • 🔄 Operators need workarounds just to fit or orient the part

You didn’t design it wrong — it just wasn’t optimized for how it would be built.

 

And in 2025, when launch schedules are compressed and margins are tight, DFM is no longer a nice-to-have. It’s your launch insurance.

You’re the Hero — DFM Is Your Superpower

As the design lead, you’re the one driving how a part looks, performs, and comes together. DFM isn’t about limiting that — it’s about helping your ideas go from concept to reality without backtracking.

Think of it like having a production lens baked into your design process. It helps you:

  • 🔍 Catch geometry that’s hard to tool or form

  • 🧰 Reduce secondary operations

  • 🧩 Simplify part orientation and fixturing

  • 🌱 Improve material yield and reduce waste

 

By 2025, many design teams are using in-CAD DFM tools (like DFMXpress or DFMPro) to flag these issues in real time — long before they become expensive changes.

The Plan: Bring DFM In Before the Design Is Locked

Here’s how top-performing teams stay ahead:

  • 🧠 Start with a Process in Mind
    Know whether your part will be stamped, machined, or EDM’d. The process drives everything — from radius limits to material choice.

  • 📐 Use GD&T Wisely
    Apply tighter tolerances only where it matters. Over-tolerancing leads to unnecessary cost and complexity.

  • 🛠️ Design for Assembly
    Include features like locators, orientation tabs, or nesting aids. These save time and reduce human error.

  • 🤝 Loop in Tooling Early
    Have a quick design review before finalizing your model. A 20-minute call can save 2 weeks in revisions.

 

You’re not just designing parts — you’re designing a smoother path to market.

What Success Looks Like

When DFM is part of your process, here’s what you gain:

  • 🚀 Faster tooling and smoother launches

  • 💰 Lower rework and tooling costs

  • 🧾 Cleaner alignment between design and production

  • 📉 Fewer engineering change orders

 

You keep control of your design — and make it production-ready from day one.

Connector Confidence

How To Achieve Micron-Level Accuracy in High-Density Power Systems

Issue 048

We don’t often think of electrical terminals and busbars as delicate — but when space is tight and current is high, precision matters more than ever.

 

In power management and industrial control systems, one poorly formed tab or misaligned hole can ripple across the entire assembly. At best, it adds time and frustration. At worst, it leads to overheated joints, installation failures, or product returns.

The Invisible Problem: Small Errors, Big Consequences

Let’s face it — not every stamped part needs surgical precision. But as systems shrink and performance demands rise, tighter tolerances are showing up in more places than ever.

 

Control panels, switchgear, and circuit breakers are increasingly packed with dense, high-function connections. Even a small deviation — say, 0.002″ — can:

  • 🔄 Throw off alignment

  • 🔌 Impact mating force

  • 🛠️ Add stress to fasteners or contacts

  • 🚫 Cause subtle, hard-to-detect installation failures

  •  

That’s why more engineering teams now specify tools and dies that can consistently hold ±0.0005” or better across long production runs — especially for parts like:

  • 🧲 Copper terminals and lugs

  • ⚡ High-density busbars

  • 🧩 Multi-pin connector frames

  • 📡 EMI shielding components

  •  

 

When every piece needs to drop in seamlessly, dimensional repeatability becomes your best friend.

You're the Hero — But You Need Control

If you manage a product line or global sourcing program, you know it’s not just about meeting spec. It’s about reliability over time — in every plant, on every shift.

But here’s the reality:
✅ Tolerances drift.
⚠️ Tool wear happens.
📉 Processes lose control.

By the time it shows up on the line, it’s already too late.

 

Your best move? Partner with tooling experts who design for long-run consistency, back their work with real metrology, and build inspection gages that validate not just size, but positional accuracy like GD&T features.

 

 

No, not every job needs ±0.0001”. But when it does matter, you want to know your supplier can deliver — and repeat it.

The Plan: Build Consistency Into the Tooling

Fewer quality surprises. Faster fit-ups. Higher yield. That starts where your parts do — at the tool and gage level.

Here’s what to prioritize:

  • 🧠 Micron-level craftsmanship on critical die features, even when tolerances allow for more.

  • 🛠️ Custom gages that inspect true position, flatness, and compound profiles — not just diameter.

  • 🔁 Feedback-driven maintenance cycles to sustain tight tolerances over time.

  • 🏭 U.S.-based production that gives you fast response times and supply chain transparency.

 

A solid foundation doesn’t just protect you — it compounds efficiency over time.

What Success Looks Like

Picture this:

  • ✅ Terminals that seat without tweaks

  • ✅ Busbars that align without adjustments

  • ✅ Connectors that pass first article, every time

That’s not just quality — that’s confidence in your product.

The right tools won’t just make better parts.


They’ll help you scale faster, launch smoother, and sleep better knowing your components will perform exactly as designed.

Joint Precision

How Vendor–Buyer Collaboration is Reshaping Complex Part Engineering

Issue 045

Imagine this: You’re reviewing a new part design when a familiar wrench is thrown in the gears—steel prices just spiked. Again.

As of March 2025, the U.S. has reinstated 25% tariffs on imported steel and aluminum under renewed trade policy shifts. For manufacturers, this means every gram of metal now counts more than ever. If you’re an engineer or buyer in this environment, you’re not just building components—you’re building strategy.

 

And the smartest strategies? They start with collaboration.

The Case for Collaboration

When engineers and procurement teams bring their suppliers into the conversation early—really early—the impact is huge. These vendor–buyer partnerships are turning complex challenges into lean, resilient solutions.

Why now? Because tariffs, supply chain delays, and rising costs are turning what used to be routine into risk. Designing smarter, more cost-effective parts requires more than specs and spreadsheets. It requires open communication with the folks who turn your designs into real-world parts.

What Collaboration Actually Looks Like

Here’s how successful teams are reshaping complex part engineering through collaboration:

 

🧠 Joint Design Reviews

Buyers and engineers are sitting down with tooling and stamping vendors during the concept phase—not just after finalizing CAD files. This allows both sides to explore:

– Alternative geometries to reduce tooling complexity

– Material substitutions to navigate tariff-affected imports

– Better tolerance stacks to reduce scrap and rework

 

🔩 In-Die Assembly Integration

Early collaboration often uncovers opportunities to combine operations. For instance:

– Threading, contact insertion, or multi-metal joining can happen inside the stamping die

– Reduces the need for secondary processes or sub-assembly stages

– Cuts labor, shortens lead times, and improves repeatability

 

🇺🇸 Leveraging North American Expertise

With global logistics still shaky, many teams are finding value in local partnerships. Domestic manufacturers offer:

– Faster prototyping cycles and communication

– Built-in compliance with ISO and ITAR requirements

– Greater control over tooling changes and iteration timelines

The Tangible Payoff

A McKinsey study found that digital collaboration tools—often part of these vendor-partnered workflows—can reduce scrap by up to 25% and increase revenue by 0.5%. But even beyond the numbers, there’s value in resilience:

 

  • Fewer surprises during production

  • More predictable costs

  • Better alignment between design intent and manufacturing reality

Real-World Example

Let’s say a buyer and design engineer team up with a stamping supplier early in a project. Instead of specifying imported 301 stainless steel, the supplier recommends a domestically sourced alternative with similar performance. Together, they adjust the component geometry to reduce form stress—allowing for simpler tooling and lower tonnage requirements.

 

The result? Lower material costs, fewer tool maintenance issues, and a more robust supply chain—all made possible through early collaboration.

Key-Takeaway

In today’s tariff-heavy, cost-sensitive environment, collaboration isn’t just a nice-to-have—it’s a strategic must. When vendors and buyers co-engineer solutions, the results are more resilient designs, faster turnaround times, and smarter production workflows.

Don’t wait until designs are frozen. Pull your partners in early. You’ll be glad you did.

Modular Wins

How to adapt to tariff shifts with smarter modular product design.

Issue 042

If you’re part of a product design or engineering team, you’re likely feeling the impact of recent tariff changes—especially if you’re sourcing components made from steel or aluminum. As of March 12, 2025, the United States imposed a 25% tariff on all steel and aluminum imports, including those from Canada, aiming to protect domestic industries.

 

 

So, how do savvy teams stay ahead of unpredictable price hikes and supply chain disruptions? One word: modularity.


Modular design isn’t just about simplifying your product—it’s about building flexibility into your system so you can adjust quickly when circumstances change. In today’s environment, things are changing fast.

 

 

Let’s explore how modular thinking—and collaborating with your vendors—can give you a competitive edge.

Why Modularity Matters Now More Than Ever

Imagine this: a key steel component in your assembly just increased in price due to new tariffs. Do you halt production? Delay delivery? Absorb the cost? Not if your product is modular.

When your components are designed to be interchangeable, it’s easier to swap materials, tweak parts, or adjust sourcing—without redesigning the entire product.

 

✔️ Need to switch from steel to aluminum because of tariffs?

✔️ Want to localize parts sourcing without altering your core design?

✔️ Looking to add or remove functionality based on cost constraints?

 

Modular design makes all of this possible. And here’s the best part: it doesn’t require a complete redesign—just smarter planning upfront.

Team Up with Vendors to Build Flexibility In

Let’s be honest. No one understands the production floor like your vendors do. When you’re designing modular components, involving your stamped parts or tooling vendor early can be crucial.

 

  • > Flexible Tooling Solutions: Vendors can help design modular dies or quick-change tooling setups so parts can be adapted with minimal rework. This is invaluable when you need to pivot quickly.

  • > Scalable Production Plans: A modular setup allows your vendor to scale production more easily. If tariffs force you to change materials or quantities, a modular approach enables both of you to respond swiftly—without overhauling the production line.

  • > Alternate Part Development: By co-developing interchangeable parts with multiple material options, you can pre-plan responses to tariff shifts—before they occur.

  •  

 

Pro Tip: Host a modular design workshop with your vendor. You’d be surprised at the efficiency ideas they’ll bring to the table.

Real-World Wins from Modular Thinking

Let’s take a look at how one major U.S.-based industrial equipment manufacturer is already moving to address the latest round of tariffs through modular design.

 

In early March 2025, when the U.S. reimposed a 25% tariff on Canadian steel and aluminum, this company—already familiar with trade-related disruptions—knew they had to act fast. Thankfully, their product teams had already begun adopting modular architecture over the past few years in response to previous supply chain shocks. Because of this foresight, they were well-positioned to adapt quickly.

 

Now, with tariffs driving up steel prices, they’re working with their stamped parts vendor to accelerate development of modular component alternatives using domestic and tariff-free materials. Their teams are focused on:


  • > Swapping structural parts for interchangeable modules built from aluminum and other non-tariffed materials

  • > Adjusting tooling setups to accommodate material changes with minimal disruption

  • > Building in sourcing flexibility by designing components that can be produced by multiple vendors


While it’s early days, initial results are promising. Their engineering and procurement teams report:

  • ⚙️ Greater agility in material substitution

  • ⏱️ Faster retooling times for updated modules

  • 📦 Less reliance on tariffed steel due to adaptable sourcing strategies

  •  

 

They’re not done yet—but their modular foundation is helping them pivot faster than if they were locked into a rigid product design.

Your Move: Build Flexibility into Your Designs

You can’t always predict tariffs. But you can predict how well your team handles them. Modular design principles make your products easier to adapt, quicker to scale, and more cost-effective to update.

And when you involve your vendors in the process early, you’ll discover options that go beyond internal brainstorming.

✅ Rethink your next product line with modular architecture

✅ Build in sourcing flexibility for critical parts

✅ Collaborate with vendors to simplify tooling and reduce lead times

Tarrif Shield

Engineering your way around steel tariff pressures.

Issue 039

Hey there! 👋 If you’re part of a product design or engineering team right now, chances are you’re feeling the squeeze from rising steel tariffs, especially those recent hikes on Canadian imports. Costs are climbing 📈, your budgets are tightening, and procurement is pushing back—making your job tougher than ever. Sounds relatable, doesn’t it?

 

 

But here’s the good news: these tariff pressures don’t need to slow you down. With just a bit of clever thinking and some fresh engineering tactics, you can actually reduce reliance on tariff-impacted materials, control your costs, and even boost product performance. Let’s explore some smart (and totally achievable) ways you can do just that.

Swap Smart: Look Beyond Canadian Steel

Steel is great—solid, reliable, familiar—but tariffs have shaken things up. It’s a perfect time to get creative and consider other materials that might deliver even better performance without the tariff pain.

One promising alternative is aluminum alloys. 🚗 Lightweight, strong, and corrosion-resistant, aluminum is widely available within the US from companies like Alcoa or Kaiser Aluminum, or from reliable trade partners outside Canada. Industries like automotive and aerospace are already thriving using aluminum due to its lightweight properties and strength.

Magnesium alloys ⚙️ are another solid substitute. Magnesium, available domestically from suppliers right here in the US, offers superior strength-to-weight ratios. This makes magnesium alloys an excellent pick for aerospace, defense, automotive, and even electronics sectors. The bonus? No tariff headaches, shorter lead times, and predictable costs.

And don’t forget engineered plastics and composite materials from domestic suppliers such as DuPont or Eastman Chemical 🌐. These materials are versatile, durable, and easy to work with, potentially reducing manufacturing complexity and costs, all while shielding you from steel tariff spikes.

 

Ask yourself: Could one of these materials work even better for your next project?

Lean Engineering: Design More with Less

Now let’s get practical. Imagine packing for a short trip 🧳—would you fill your suitcase to the brim, or pack just what’s necessary? The same principle applies to product design.

By strategically optimizing your designs, you use less material without sacrificing strength or performance. Consider lean methods like strategic ribbing, cut-outs, or using thinner gauge metals in areas that aren’t load-critical. Just these small changes can help reduce your material usage by 10–15%, directly lowering your exposure to tariff-influenced costs.

 

Your metal stamping vendor can be a valuable partner here. Collaborating early ensures your designs are not only smart but also easy and cost-effective to manufacture.

Real-Life Collaboration: Engineering & Vendor Teamwork

Here’s a scenario that might sound familiar:

Picture yourself working as a design engineer at an industrial machinery company facing steep costs from steel tariffs. Instead of absorbing those expenses or passing them to customers, you team up 🤝 with your stamped-parts vendor to innovate. Together, you identify a few key steel parts and substitute them with domestically sourced aluminum alloys. You optimize the geometry to reduce material usage, and voilà—your costs drop, your product performance improves, and your supply chain becomes stronger than ever.

 

Collaboration like this is no longer just a nice-to-have—it’s becoming essential. Working closely with your vendors can help you uncover hidden opportunities to navigate around tariff pressures smoothly.

Your Next Move: Take Action

Ready to tackle tariffs head-on? It all starts with conversations. 📢 Reach out to your metal stamping vendors, get procurement and production involved early, and consider domestically available materials or tariff-friendly trade partners. By making these strategic moves, you’ll position your team to remain agile, cost-effective, and innovative—no matter what tariffs come your way.

You’ve got this! 💪

Stamped for Success

Smarter Stamping Strategies for Electrical Design Engineers

Issue 036

When designing stamped metal components for electrical applications, even small adjustments can make a big difference in cost, efficiency, and long-term reliability. Whether you’re working on busbars, terminals, or brackets, understanding material selection, in-die assembly, and stamping process optimizations can help you cut waste, speed up production, and improve performance.

 

Let’s dive into key design strategies that can save time and money while ensuring your stamped parts meet performance standards.

Choosing the Right Material: Performance vs. Cost vs. Longevity

Material selection in electrical stamping is like choosing the right engine for a performance vehicleconductivity, strength, and cost all matter.

Here’s a breakdown of common materials for stamped electrical components:

Copper – The gold standard for conductivity. Great for busbars and terminals, but expensive. Plating with tin, nickel, or silver helps prevent oxidation.

AluminumA lower-cost, lightweight alternative, but it’s not a direct replacement for copper in all cases. Protective coatings (tin or nickel) are often required to prevent oxidation and ensure long-term reliability.

Stainless SteelHigh strength and corrosion resistance, but significantly lower conductivity. Best for brackets and structural components, not power distribution.

Beryllium Copper & Phosphor Bronze – Excellent for high-precision connectors due to their spring-like properties and wear resistance.

 

💡 Pro Tip: If switching from copper to aluminum in busbar applications, ensure proper surface treatments to prevent oxidation and galvanic corrosion.

In-Die Assembly: When It Works (and When It Doesn't)

Instead of stamping a part, then assembling it separately, modern die technology allows multiple processes in one stroke—reducing labor and cycle time.

🔹 In-Die Tapping – Eliminates secondary machining for threaded holes.

🔹 In-Die Riveting & Contact Insertion – Automates terminal or connector placement for perfect alignment.

🔹 In-Die Bending & Forming – Reduces multiple press operations into one efficient process.

 

💡 Pro Tip: In-die assembly works best for high-volume production but may not be cost-effective for low-volume or highly complex designs due to longer setup times and increased die wear.

High-Speed Stamping: Designing for Faster, More Efficient Production

Stamped parts are often produced in the millions, so optimizing for speed and consistency is crucial.

Uniform Material Thickness – Ensures smooth feeding in high-speed presses.

Springback Compensation – Materials like stainless steel tend to “spring back” after forming. Adjust die clearances and use secondary forming techniques to maintain accuracy.

Nesting & Progressive Die OptimizationAI-driven nesting software can improve material usage and reduce scrap rates by optimizing blank layouts.

 

💡 Pro Tip: If your part requires tight tolerances at high speeds, consider progressive die stations with built-in stress relief operations to counteract material distortion.

Final Thoughts

Smart design decisions in stamped metal components can eliminate unnecessary costs and improve efficiency.

✔️ Select materials carefully based on conductivity, corrosion resistance, and cost
✔️ Use in-die assembly where it makes sense, but weigh costs for lower-volume runs
✔️ Optimize for high-speed stamping, accounting for springback and nesting efficiency

By applying these practical strategies, you’ll create stamped parts that are cost-effective, reliable, and built for long-term success.

Material Matters

How To Avoid Costly Material Selection Mistakes in Manufacturing

Issue 033

Everything looked perfect in CAD, but when production started, problems emerged—warping, cracking, and part failures. The culprit? ❌ The wrong material choice.

 

🔴 Excessive springback – High-strength steels bend unpredictably, causing fitment issues.
🔴 Warping in aluminum – Aerospace brackets distorted due to poor formability.
🔴 Stainless steel galling – High friction caused premature tool wear and cracking.
🔴 Copper oxidation – Uncoated connectors failed due to environmental exposure.

A simple oversight in material selection can lead to expensive redesigns, unexpected costs, and frustrating delays.

✈️ Real-World Scenario: A Costly Aerospace Mistake

An aerospace manufacturer chose 7075 aluminum for a lightweight bracket, assuming it would handle stamping like other aluminum alloys. But during production, it cracked under pressure. Why? 7075 has high strength but low ductility, making it unsuitable for complex forming.

What They Should Have Done: Selected a 5000-series aluminum, which offers better formability while maintaining strength. This would have prevented cracking and costly rework.

 


🔍 Common Material Selection Pitfalls

Assuming Strength = Formability
Just because a metal is strong doesn’t mean it will form well. Advanced High-Strength Steels (AHSS) can be incredibly durable but suffer from extreme springback, requiring additional forming adjustments.

Ignoring Work Hardening
Some metals (like stainless steel) harden as they’re deformed, leading to tool wear and cracking. Annealed stainless steel is often a better choice for deep drawing.

Overlooking Surface Sensitivity
Copper provides excellent electrical conductivity but oxidizes quickly. Without proper plating or coating, connectors can degrade in performance.

Not Accounting for Thermal Expansion
Materials expand and contract at different rates. If you’re assembling components with both aluminum and steel, misalignment over time is a real risk.


🛠 How to Choose the Right Material the First Time

Match the Metal to the Manufacturing Process
If stamping is required, choose metals with high ductility. If machining, consider work-hardening tendencies and tool wear. If welding, avoid metals prone to cracking from thermal stress.

Consider Secondary Operations
Does the part need post-processing like anodizing, heat treatment, or plating? Some metals respond better than others, impacting longevity and cost.

Use Material Simulation Software
AI-driven material selection and digital twin technology allow manufacturers to predict metal behavior before production—helping prevent costly surprises.

Partner with Manufacturing Experts Early
Experienced engineers can flag potential material issues before production begins, avoiding costly trial-and-error iterations.

📌 The Takeaway

Choosing the right metal isn’t just about weight or cost—it’s about how the material behaves in the real world. A simple oversight in material selection can snowball into expensive production issues, late deliveries, and frustrated customers.

Next time you’re selecting a material, consider not just what looks good on paper, but how it will behave on the production floor. A little foresight now can save thousands (or even millions) down the road.

Engineering Mistakes

Why Over-Engineering Slows Down Product Manufacturing

Issue 030

When it comes to precision manufacturing, more complexity isn’t always better. In fact, some of the most expensive and time-consuming mistakes in production come from over-engineered designs—parts with unnecessary tight tolerances, excessive machining, and material choices that don’t align with manufacturing efficiency.

 

The truth is, not every feature needs to be machined to perfection, and not every part needs ultra-high precision. Sometimes, simplifying a design can save thousands in production costs while maintaining the same functionality.

 

Let’s break down how over-engineering hurts production—and what you can do to avoid it.

The Cost of Over-Engineering: A Real-World Example

A medical device company developed a high-precision bracket designed for a surgical tool. The part was:

🔴 Machined from an expensive aerospace-grade alloy that was difficult to work with.
🔴 Designed with unnecessary tight tolerances that required multiple machining setups.
🔴 Too complex for efficient assembly, increasing production cycle time.

The result? Production costs skyrocketed, and lead times were much longer than necessary.

By optimizing the design for manufacturability, they were able to:

Reduce production costs by 25%
Eliminate unnecessary machining steps
Use a more cost-effective material without sacrificing performance

The best part? The simplified design worked just as well as the original—without the added waste.

Why Over-Engineering Hurts Manufacturing Efficiency

Over-engineering isn’t just about making a part “too precise”—it often leads to:

🔹 Unnecessary Machining: More features mean longer production times and higher costs.
🔹 Material Waste: Selecting high-cost materials when a more economical option would work just as well.
🔹 Assembly Bottlenecks: Overcomplicated designs lead to slower assembly and more quality control checks.
🔹 Higher Scrap Rates: Tight tolerances and complex geometries often result in higher rejection rates.

Simply put—just because you can design it doesn’t mean you should.

How to Simplify Designs Without Sacrificing Functionality

If you want to reduce costs, improve efficiency, and speed up production, start designing with manufacturability in mind.

1. Rethink Tolerances—Are They Really Necessary?

Not every part needs microscopic precision—tight tolerances should be reserved for critical functional areas.

✔️ Ask: Will a looser tolerance still allow the part to function as required?
✔️ Work with manufacturers to determine practical tolerances that maintain performance without unnecessary costs.


2. Choose Materials That Match the Manufacturing Process

High-end alloys may be stronger, lighter, or corrosion-resistant, but if they increase machining difficulty, they may not be worth the cost.

✔️ Consider alternative materials that offer similar performance but are easier to machine or form.
✔️ Use stamping or forming instead of machining for simple geometries to reduce material waste.


3. Minimize Secondary Operations & Unnecessary Features

Every additional machining, finishing, or assembly step adds cost and time.

✔️ Eliminate sharp corners, deep pockets, and complex geometries if they don’t add value.
✔️ Consider progressive stamping dies instead of machining for high-volume production.
✔️ Use in-die tapping or forming to eliminate extra drilling or secondary forming operations.

The Bottom Line: Simplification is the Key to Cost-Effective Manufacturing

A well-designed part isn’t just about function—it’s about manufacturability.

By optimizing designs for efficiency, you can:

✔️ Reduce lead times and production costs
✔️ Improve consistency and quality
✔️ Streamline machining, stamping, and assembly

And the best part? A simpler design is often just as effective as an over-engineered one.

Design for Manufacturing

Why Great Engineering Still Fails in Production

Issue 027

You’ve designed a high-performance electrical component—optimized for function, tested in simulations, and approved by the team. Everything looks great on paper. But when the part reaches production, the bad news hits: it can’t be efficiently stamped, formed, or assembled at scale.


Now, you’re facing expensive rework, last-minute design changes, and frustrating delays.


What went wrong? It wasn’t designed with manufacturability in mind.


This is a common challenge in manufacturing—a disconnect between engineering and production. No matter how perfect a design seems in CAD, if it’s difficult (or impossible) to manufacture efficiently, it fails where it matters most: in production.


The good news? Avoiding these failures is achievable by applying Design for Manufacturing (DFM) principles early in the process.


Let’s talk about why great designs fail in production—and how you can prevent it from happening.

1/3 | Why Some of the Best Engineering Designs Fail in Production

Engineering and manufacturing don’t always speak the same language—but they should. A design might be functionally sound, but if it creates manufacturing bottlenecks, excessive material waste, or tooling challenges, it’s not actually a good design.

 

Here’s what often goes wrong:

 

🔴 Overly Tight Tolerances – Strict tolerances can increase machining and stamping costs and may lead to unnecessary rework. In many cases, relaxed tolerances can achieve the same performance at a lower cost.

 

🔴 Complex Geometries That Are Difficult to Manufacture – Intricate shapes with sharp corners or deep draws might look impressive in CAD, but they can be challenging to produce efficiently at scale.

 

🔴 Inappropriate Material Choices – Some materials may crack or warp during stamping or forming. If material behavior isn’t considered, production failures are likely.

 

🔴 Ignoring Tooling and Die Constraints – Designs requiring multiple setups, excessive trimming, or specialized tooling can increase costs and production time. Aligning designs with existing tooling capabilities can save both time and money.

 

Sound familiar? These issues don’t just lead to delays—they impact efficiency, cost, and overall product quality.

2/3 | How to Optimize Designs for Manufacturability (Without Compromising Function)

1. Design with the Manufacturing Process in Mind

Are you planning to stamp, form, machine, or laser cut the part? Each process has specific design considerations. Before finalizing a design, evaluate how the part will be produced and adjust accordingly.

 

✔️ For stamped parts – Avoid deep draws, sharp internal corners, and excessive bends that may necessitate secondary operations.

 

✔️ For machined parts – Minimize unnecessary tight tolerances and complex features that can increase production time.

 

✔️ For formed parts – Account for material springback and flow to prevent distortion.

 

2. Balance Tolerances for Cost and Performance

Not every feature requires machining to ±0.0005” precision. Tight tolerances can lead to higher scrap rates and extended lead times.

 

✅ Consider: Can a slightly looser tolerance maintain functionality?

 

✅ Collaborate with the manufacturing team to establish practical, achievable tolerances that won’t unnecessarily increase costs.

 

3. Select Materials Suited for Manufacturing

Some materials are easy to machine but difficult to stamp. Others may be lightweight but prone to warping under heat or pressure.

 

🔹 High-strength alloys might require special tooling and slow down stamping processes.

 

🔹 Certain metals are suitable for deep drawing, while others may crack under stress.

 

Understanding material properties early on can prevent costly issues during production.

 

4. Engage Tooling and Stamping Experts Early

The simplest way to avoid manufacturability problems is to involve the manufacturing team before finalizing the design.

 

🏭 Tooling engineers can identify potential issues before they escalate into expensive production problems.

 

💡 Stamping and forming specialists can recommend minor adjustments that preserve functionality while enhancing manufacturability.

 

🔍 DFM analysis tools and simulations can detect potential challenges before production begins.

 

This proactive approach can save significant time and resources.

3/3 | Final Thoughts: Design for Manufacturing Is Essential for Success

A great engineering design isn’t just about functionality—it’s about how efficiently it can be produced.

 

By incorporating Design for Manufacturing principles early, you can:

 

✔️ Minimize last-minute design changes

 

✔️ Prevent production delays and tooling issues

 

✔️ Reduce costs while maintaining product quality

 

The optimal time to address manufacturability concerns? Before production even starts.

Avoid Costly Design Mistakes

How Smart Engineering Prevents Manufacturing Setbacks

Issue 024

Imagine this: Your team has invested months, perhaps even a year, crafting the perfect design. It’s innovative, meets all performance criteria, and looks impeccable in the CAD model. The excitement is palpable as you move to production, only to hit a wall: “We’ve encountered an issue. The design isn’t manufacturable as it stands.”

Suddenly, you’re facing costly redesigns, production delays, and material waste. It’s a scenario that’s all too common in the manufacturing world. But here’s the silver lining: These pitfalls are avoidable with a proactive approach.

1/4 | Bridging the Gap Between Design and Manufacturing

Designers excel at creating cutting-edge solutions. However, a design that shines in the virtual realm can stumble on the production floor. Why does this happen?

  • – Unrealistic Tolerances: Specifications tighter than necessary can complicate manufacturing without adding value.
  • – Complex Geometries: Intricate designs may require specialized tooling or processes, increasing costs.
  • – Material Choices: Selecting materials without considering their manufacturability can lead to issues like warping or difficulty in processing.
  • – Overlooking Secondary Operations: Neglecting processes like deburring or surface finishing can affect the final product’s quality.

The crux of the problem is a lack of early collaboration between design and manufacturing teams.

2/4 | The High Cost of Late-Stage Design Changes

Discovering manufacturability issues late in the process can lead to:

  • – Expensive Rework: Modifying tooling or redesigning parts after production has begun is costly.
  • – Production Delays: Unplanned changes can halt production lines, leading to missed deadlines.
  • – Material Waste: Incorrect designs can result in unusable parts, wasting resources.
  • – Inefficiencies: Designs not optimized for manufacturing can slow down production and increase costs.

3/4 | Embracing Design for Manufacturability (DFM)

To sidestep these issues, integrate DFM principles early in the design process:

  1. Collaborate Early: Involve manufacturing engineers from the outset. Their insights can identify potential production challenges before they become problems.

  2. Simplify Designs: Aim for simplicity. Complex designs can increase the likelihood of manufacturing errors and elevate costs.

  3. Select Appropriate Materials: Choose materials that are not only suitable for the product’s function but also compatible with manufacturing capabilities.

  4. Plan for Secondary Operations: Consider all necessary post-production processes to ensure the final product meets quality standards.

  5. Leverage Advanced Tools: Utilize modern simulation software to predict how designs will perform in real-world manufacturing scenarios. Tools like Finite Element Analysis (FEA) can identify potential issues before they arise.

4/4 | A Proactive Path Forward

By embedding manufacturability considerations into the design phase, you’re not just preventing headaches down the line—you’re fostering a more efficient, cost-effective, and streamlined production process. This proactive approach ensures that your innovative designs transition smoothly from concept to reality, keeping projects on schedule and within budget.
