Customer Case Study
Ordnance Fuzing
A defense OEM passed MIL-Spec testing with ITAR-compliant fuzing components built to print.
The Problem
A U.S. defense contractor needed stamped components for an ordnance fuzing system. These parts had to survive extreme vibration, shock, and temperature swings — all while maintaining precise fit in the fuze assembly.
Their previous supplier struggled to hold tolerances consistently and lacked ITAR registration, which created compliance and security risks. The contractor needed a U.S.-based partner who could deliver tight-tolerance, MIL-spec parts under full ITAR control.
The Solution
We took ownership of the program from design review through production.
1) Stamped fuzing components using hardened progressive dies built in-house to maintain repeatability at volume.
2) Held ±0.0015” tolerances on critical features that controlled alignment and electrical continuity inside the fuze.
3) Designed custom gaging for in-line checks, ensuring parts met spec before they ever left the press.
4) Maintained full ITAR compliance — from secure document handling to controlled shipping — giving the contractor confidence in audit readiness.
Every part was engineered and produced with defense-grade traceability in mind.
The Results
The fuzing components passed MIL-spec reliability testing and were integrated into production on schedule. By keeping tooling, stamping, and inspection in-house under ITAR, we eliminated compliance concerns and gave the contractor a reliable, long-term supply chain partner.
For the customer, it wasn’t just about getting parts — it was about getting a process they could trust in the field.
Why It Matters
Ordnance fuzing components aren’t forgiving. If tolerances slip, assemblies fail — and in defense, failure isn’t an option. That’s why Gromax stamps these parts with precision, builds the gaging to verify them, and runs everything under ITAR and MIL-spec compliance.
