High-Precision Stamping

Production that matches the print & product.

We stamp what we design.


Our tooling, stamping, and gaging teams share the same floor.

Every progressive and reel-to-reel job runs in production presses during die debug—so when we say it’s capable, it’s proven.

That closed loop between design and production keeps performance locked in from first hit to full production.

 

Progressive & Reel-to-Reel Stamping

Progressive & Reel-to-Reel Stamping

High-volume forming on Class-A dies built in-house.

Consistent parts, stable carriers, fast changeovers.

Capability to ±0.0015″

Capability to ±0.0015″

Proven at rate with real press data.

GR&R-correlated inspection—feasible tolerances, not guesses.

Thin, Coined & Formed Features

Thin, Coined & Formed Features

Control forming stress, stretch, and springback to hold geometry through plating or molding.

Dimensional stability at rate, not just at first article.

In-Press Monitoring & Control

In-Press Monitoring & Control

Feed, buckle, part-out, and slug-detect sensors monitor performance in real time.

Prevents drift and protects tools from costly crashes.

Traceable, Audit-Ready Documentation

Traceable, Audit-Ready Documentation

Each production lot is tied to inspection and material records.

Capability, PPAP, and FAIR documentation all traceable and clean.

Downstream-Ready & Secondary Ops

Downstream-Ready & Secondary Ops

Carriers engineered for plating, overmold, and automation. Selective plating, coin/emboss, tap/form, part marking, light sub-assembly, reel-to-reel handoff.

Reliable handoffs, fewer rejects, smoother integration.

Frequently Asked Questions (FAQ)

 Typically ±0.0015″; tighter on select geometries/alloys.

Yes—inspect, validate, and quote run-at-rate.

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

ELECTRICAL & POWER

Your challenge: Heat rise and flatness variation in busbars and contacts cause torque loss or hot spots once assembled.


Our solution: Progressive and reel-to-reel stamping on Class-A dies verified at rate; coined current paths, stress-relief forming, and in-press monitoring ensure geometry and conductivity hold through plating


Your benefit: Flat, dimensionally stable parts that install cleanly, maintain electrical contact, and pass heat-rise and torque tests downstream.

ELECTRONICS & SENSORS

Your challenge: Micro-contacts and terminals distort, and plating growth shifts fit or force, breaking PCB alignment.

Our solution: ±0.0015″ capability on micro-features, with post-plate growth and springback modeled in the die; carrier support and real-time feed monitoring protect geometry at volume.

Your benefit: Repeatable insertion and extraction forces, clean PCB fits, and consistent signal reliability through final assembly.

DEFENSE & AEROSPACE

Your challenge: Zero-escape performance under shock, vibration, and thermal extremes—plus audit-ready documentation.

Our solution: Stamping validated on production presses with in-press SPC, buckle and slug sensors, and MIL-grade traceability; capability confirmed by GR&R and PPAP data.

Your benefit: Mission-critical parts that hold tolerance through service life, backed by complete documentation for qualification or re-inspection.

MEDICAL DEVICE & EQUIPMENT

Your challenge: Burrs, deformation, or finish inconsistencies on tiny parts trigger validation failures or biocompatibility issues.

Our solution: Fine-blanked and coined features, controlled bend radii, and post-form inspection that mirrors assembly and sterilization conditions.

Your benefit: Clean, burr-free components that assemble smoothly, pass FDA/ISO audits, and maintain precision through sterilization and packaging.

INDUSTRIAL MACHINERY

Your challenge: High load, vibration, and wear expose forming stress and tolerance drift in brackets, clips, and housings.

Our solution: Progressive dies tuned for uniform forming pressure, real-time feed and part-out sensors, and hardened steels to maintain geometry at speed.

Your benefit: Parts that install easily, hold alignment under vibration, and extend equipment uptime with less rework and maintenance.

MOLDING-INTEGRATED APPLICATIONS

Your challenge: Metal inserts deform or shift during overmolding, causing misalignment and weak electrical contact.

Our solution: Reel-to-reel stamping with carriers designed for thermal stability and mechanical lock; post-mold gage correlation ensures seating accuracy.

Your benefit: Inserts that stay true through molding and assembly, preserving electrical and mechanical integrity and cutting scrap.
