Gromax builds and maintains progressive dies in-house and runs high-volume stampings when packaging is tight, tolerances are unforgiving, or springback drives the result.
STAMPING
TOOLING
GAGES
designed & built for complex critical components
New designs pushing limits
• Tight tolerances on formed features
• Thin material, complex bends, springback concerns
• Burr direction, edge condition, or cosmetic requirements
• What we’ll do: quick DFM review, forming risk check, and an inspection plan that holds up in production.
Early DFM before you cut steel
• Find tolerance traps and stack issues early
• Flag features that want redesign before tooling
• Recommend datums and gage approach that match the print intent
• Result: fewer surprises at tool tryout and faster launch.
Trouble through plating or molding
• Plating thickness/coverage can change fit and function
• Insert-molded/overmolded parts need consistent geometry and clean surfaces
• We’ll call out burr, edge break, and handling details that matter later
• Result: fewer rejects after finishing and fewer downstream line stops.
Parts failing in the field
• Drift from tool wear or inconsistent measurement methods
• Burrs, cracks, plating issues, or contact force changes over time
• “Looks fine” parts that don’t behave fine in real use
• What we’ll do: root cause support + process fixes to stop repeat escapes.
Second source for critical work
• A backup supplier who can truly match the part
• Tooling and inspection discipline you can trust
• We’ll focus on: repeatability, measurement alignment, and stable capability—not just first articles.
Reshoring & supplier cleanup
• Long lead times, communication gaps, quality drift
• Too many handoffs between tool shop, stamper, and finisher
• What changes with us: fewer suppliers, tighter control, cleaner accountability.

WE SERVE
Backed by 50+ years industry experience, Gromax helps OEMs and Tier 1s solve complex build, tolerance, and compliance challenges—fast.
WHAT'S DRIVING PART
complexity?
OEMs are shrinking assemblies while adding more formed, current-carrying features—so there’s less room for variation at production volume.
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.

We’ll flag risks and suggest a production-ready approach.
