Tool & Die Design + Build

Tooling built beside the presses it runs on.

We build where we run.

Every progressive die we build is designed, debugged, and qualified on the same production presses that will run your parts.

Our tooling, stamping, and gaging teams share one floor—so every decision connects design intent to real-world performance.

Progressive Die Concept & Station Mapping

Progressive Die Concept & Station Mapping

We map ops, carriers, pilots, and forming sequence so the strip stays stable and critical features are protected.

Reduces debugging, accelerates launch, and improves long-term capability.

Class-A Design & Construction

Class-A Design & Construction

Built for longevity with robust steels, precision fits, and serviceable inserts at wear zones.

Less downtime, more consistency, and longer tool life.

Sensorized, Error-Proofed Tooling

Sensorized, Error-Proofed Tooling

Feed, buckle, part-out, slug detect, and height sensors placed where they matter.

Stops crashes, protects tools, and prevents drift before it becomes scrap..

Reel-to-Reel & Selective-Plating Carriers

Reel-to-Reel & Selective-Plating Carriers

Carriers and pitch designed to match plating, molding, and automation partners.

Clean handoffs, higher yield, smoother downstream flow.

Coining, Embossing & Controlled Form-to-Hole

Coining, Embossing & Controlled Form-to-Hole

We sequence forming, coining, and reliefs to manage springback and stretch.

Dimensional relationships stay stable at rate—not just at first article./STRONG>

Maintenance & Spares Planning

Maintenance & Spares Planning

Quick-change wear inserts and kitted spares with each tool.

→ Faster recoveries, minimal downtime, predictable PM schedules.

Frequently Asked Questions (FAQ)

Yes—shared components simplify maintenance and reduce downtime.

 In-house design/build shortens iteration; we’ll quote timing based on scope.

 Yes—carriers and pitch are engineered to match your partners’ process windows.

ELECTRICAL & POWER

Your challenge: Heat rise, fit, and flatness issues in busbars, contacts, and switchgear only show up under load.

Our solution: Class-A progressive dies with 0.0001″ fit precision, stable datums, and sensorized die protection. Coined and formed zones are simulated before steel is cut to control conductivity and geometry.


Your benefit: Flat, conductive parts that assemble cleanly, hold torque, and maintain performance through plating and installation.

ELECTRONICS & SENSORS

Your challenge: Micro-features distort and contact force drifts after plating or during volume runs.

Our solution:
Dies built with micro-clearance inserts, springback and post-plate growth compensation, and in-press monitoring for feed and buckle.

Your benefit:
Stable insertion force, precise fits, higher yields, and repeatable performance in the final PCB or housing.

DEFENSE & AEROSPACE

Your challenge: Mission-critical repeatability under vibration, temperature, and audit scrutiny.

Our solution: Tool steels and coatings for long-run dimensional stability, in-press SPC and die protection to prevent drift, and PPAP/MIL documentation for traceability.

Your benefit: Tight, verified parts that pass qualification the first time and stay in spec through service life and re-inspection.

MEDICAL DEVICE & EQUIPMENT

Your challenge: Micro-burrs, deformation, or finish variation can derail validation and FDA approval.

Our solution: Fine-blanked or coined edges, controlled forming radii, and polish or coating plans aligned to sterilization steps. Dies are tuned with real-material forming data before release.

Your benefit: Clean, burr-free components that assemble correctly, pass validation, and stay consistent across lots.

INDUSTRIAL MACHINERY

Your challenge: High load, vibration, and wear expose weak bend zones and tolerance drift.

Our solution: Reinforced die stations, wear-resistant inserts, and flatness control features built into the strip. Quick-change modules simplify maintenance.

Your benefit: Parts that install easily, resist fatigue, and extend uptime—lower maintenance, steadier OEE.

MOLDING-INTEGRATED APPLICATIONS

Your challenge: Overmolded inserts deform or shift, causing alignment and electrical failures.

Our solution: Tooling co-designed with molders—carriers and datums matched to mold flow, plating windows built in, and mechanical locks designed into the die.

Your benefit: Inserts that hold position through molding and maintain mechanical and electrical integrity downstream.
