Why Investment Casting for Firearm Parts?

Firearm parts are small, detailed and held to tight dimensions. Machining them from solid wastes material and takes time. Investment casting produces the part close to its final shape, so machining stays on the surfaces that need it and the unit cost falls in series production.

Materials

Most firearm parts we cast are in 4140 and low-carbon steels. 4140 gains strength and wear resistance through heat treatment. For parts that need corrosion resistance, we also cast 304 and 316 stainless steel.

Tolerances and Quality

We cast to tolerances up to VDG P690 D3. Production runs under an ISO 9001 quality management system. See our quality page for details.
