TOOLING&

STAMPING

designed & built for complex critical components

WHAT'S DRIVING PART

complexity?

OEMs are packing more power into smaller assemblies—so stamped components must stay consistent at production volume.

That’s where Gromax fits: in-house progressive tooling and high-volume stampings when packaging is tight, tolerances are critical, or material behavior matters.

Challenging Geometry

Thin walls, tight bends, and tiny features are hard to stamp consistently.
We design progressive dies that keep thin, complex features consistent in production.

Tight Tolerances & Stability

Parts meet print once but drift out of spec in real production.
We build in-process control so tight dimensions stay in spec over real runs.

Demanding Materials

Copper alloys, stainless, or beryllium copper are cracking, warping, or burring.
We tune tooling for copper alloys, stainless, and BeCu so parts form cleanly.

Process Integration

Parts pass at the press but fail after plating, molding, or assembly.
We design parts and carriers to stay stable through plating, molding, and assembly.

When is

GROMAX

a good fit?

Tight packaging, high currents, or tough materials your current stamper won’t confidently take on.

You want a stamper who’ll review the print, flag risks, and shape the design before tooling is locked.

Parts pass at the press but warp, shift, or fail once they hit plating, overmolding, or automation.

Drift, scrap, or failures are hurting yield, reliability, or customer confidence.

You need a US-based, ITAR-capable backup for high-risk or regulated programs.

You’re moving work to North America or consolidating many small shops into a few proven partners.

WE SERVE

Backed by 50+ years industry experience, Gromax helps OEMs and Tier 1s solve complex build, tolerance, and compliance challenges—fast.

OUR CORE

capabilities

Gromax brings DFM, tool & die, high-precision stamping, and custom gaging together under one roof—so you get faster launches, tighter control, and fewer surprises on the floor.

DFM & Engineering Support​

 

Engineer out downstream risk before steel is cut.

We turn your end-customer requirements into CTQs (Critical to Quality) and build them into die design and gauge plans—so first articles pass and schedules hold.

Tool & Die Design + Build

 

Tooling built for repeatability—not hero setups.

Class-A progressive dies designed around your CTQs to hold capability in production, not just in a perfect run.

High‑Precision Stamping

 

Production capability that matches the print—and your customer’s end product.


Progressive stamping to ±0.0015″ with SPC (Statistical Process Control) on CTQs, so what ships performs inside your assembly and in your customer’s hands.

Custom Gaging & Fixtures

 

Measure what matters, how it functions.

Purpose-built gauges on functional datums provide real capability on the few features that drive field performance.
