WHAT WE

do

Gromax helps OEMs and Tier-1s build complex stamped components that hold critical features at volume, and run clean through downstream processes.

By aligning tooling, gaging, and production under one roof, we reduce drift, fallout, and supplier risk.

when

GROMAX

is a good fit

Problem: Tight stack-ups, springback, thin material, complex bends
Solution: DFM + CTQ control plan + inspection approach that holds up at volume
Results: Fewer tryout surprises and less drift after launch

Problem: New part development, supplier change, or reshoring
Solution: Flag forming risks, datum/tolerance traps, and gaging strategy early
Results: Faster launch and fewer ECO cycles

Problem: Fit changes after plating, overmold rejects, edge-related issues
Solution: Edge/burr strategy + plating-aware requirements + handling/packaging discipline
Results: Higher downstream yield and fewer line stops

Problem: Tool wear drift, measurement disagreement, repeat escapes
Solution: Wear-point maintenance mindset + repeatable gaging + CTQ monitoring
Results: Stable capability over real production runs

Problem: Critical component risk, supplier consolidation escapes
Solution: Align measurement, control plan, and production approach up front
Results: Less risk, fewer surprises, steadier supply
