Tool Durability

Forge tooling undergoes some of the most extreme temperatures and compressive forces found in manufacturing. The choice of material, surface finish, hardening techniques, and coatings is critical to the life of your tool. We can help with that. We know what it takes to reduce friction and wear and improve strength and fatigue resistance of your tools.


GPMI offers a variety of options to improve the durability of your forge tooling, including in-house heat treatment, cryogenic treatment, black oxide, and ion-nitriding treatments, as well as partnering with a selection of specialized coating providers to maximize tool durability.


Our proprietary heat treat/cryo/coating combination has proven to significantly reduce our customers’ cost.

Stocking Programs

GPMI’s stocking programs for high-usage tools offer the benefits of reduced lead times, lower inventory costs, and volume-based pricing.  Our customers have realized savings of 25-40% on a per-tool basis, as well as delivery times of only 2-5 days!
