PRECISION METAL STAMPING
Stamping for tight tolerances, plating, and reel-to-reel automation.
Missed tolerances or plating issues don’t just cause rejects — they halt assembly and drive up costs.
Gromax delivers precision stampings built to your specs, with in-house tooling, progressive die stamping, and optional Reel-to-Reel processing to ensure every part is ready for plating, molding, or automation.

Precision Stamping, Real Answers FAQ
Your most common stamping questions—answered by Gromax experts.
"What’s Reel-to-Reel stamping?"
It’s a process where parts remain attached to a metal carrier strip during stamping and are wound onto reels—ideal for plating, insert molding, or robotic assembly.
"Is Reel-to-Reel stamping always used?"
Not always. We recommend it for parts that need plating or molding integration. For other applications, we ship finished parts flat-packed or bulk bagged.
"How tight of a tolerance can you achieve?"
Gromax regularly holds ±0.0015” depending on the material, part design, and feature size—especially for critical dimensions or mating components.
"What materials can you stamp?"
We stamp stainless, copper, brass, beryllium copper, and specialty alloys in thicknesses from 0.002″ to 0.125″, supporting both high-conductivity and high-strength needs.
" Do you provide prototypes before production?"
Yes. We offer rapid prototyping with production-grade tooling so engineers can validate form, fit, and function before committing to high-volume builds.
