Fully Integrated Manufacturing Partner

We handle everything from design to production and compliance, ensuring precise, consistent, reliable electrical components.

Engineering Design & Pre-Production

✅ Helps prevent design changes downstream.


We collaborate with your engineers to optimize stamped components for electrical performance—reviewing materials, plating specs, current-carrying capacity, and tolerances to ensure manufacturability and compliance.

→ Learn More

Rapid Protoyping

 ✅ Speeds up qualification of electrical systems.

 

Accelerate new product launches with production-intent prototypes for terminals, busbars, grounding clips, or shields—enabling form, fit, function, and plating validation before scaling up.

 

→ Learn More

Tool & Die Design + Manufacturing

✅ Delivers precision tooling for electrical-grade parts.

 

Our in-house die shop builds progressive dies capable of stamping conductive alloys (C110 copper, C19210 bronze), integrating coining, tapping, forming in-die to reduce post-processing.

 

→ Learn More

Precision Metal Stamping

✅ Ensures electrical integrity and fit.

 

We achieve tolerances down to ±0.0015” with clean shearing and burr control to support electrical continuity, plating-readiness, and dimensional stability across high-volume runs.

 

→ Learn More

Assembly & Secondary Operations

✅ Reduces multi-vendor coordination.

 

We coordinate plating (tin, nickel, silver to ASTM specs), light assembly, or post-stamping machining—delivering plating-ready or partially assembled components for your electrical panel, connector, or enclosure builds.

 

→ Learn More

Quality Assurance & Lifecycle Support

✅ Ensures regulatory and quality compliance.

 

Every component ships with full compliance documentation (PPAP, FAIR, CMM, material/plating certs, traceability), supporting UL, IEC, RoHS, and audit requirements.

How We Add Value

We achieve tolerances down to ±0.0015” to ensure stamped parts fit and function precisely in electrical assemblies.

Our stamping process controls burrs and surface finish to meet plating specs for conductivity and corrosion resistance.

We minimize burr height to ensure electrical contact points remain clean for uninterrupted current flow.

Every production lot is tracked with material and process traceability for compliance and quality audits.

We provide full documentation packages tailored to electrical industry QA and regulatory requirements.

Our engineering team works directly with yours to design inserts prepped for reliable insert molding into electrical connectors.

Your Problems Solved

Here’s what we hear from electrical industry leaders—and how we help.

 We collaborate early with engineering teams to recommend materials, plating specs, and design-for-manufacturability adjustments—delivering a plating-ready, cost-efficient stamped busbar.

We provide production-intent prototype tooling and rapid turnaround pilot runs, enabling seamless transition from prototype to scalable production.

We supply full PPAP Levels 1–3 documentation with every production run, including FAIR, CMM reports, plating certs, and traceability records.

We deliver integrated secondary operations including plating, tapping, forming, and light assembly—reducing vendor coordination and improving accountability.

 We control burr height at the stamping stage and provide plating-ready parts, reducing rework and ensuring electrical continuity.

 We proactively deliver complete documentation packages with each lot—FAIR, PPAP, CMM, material certs—ready for your QA and compliance teams.
