Our in-house foundry uses custom presses & controls designed & built in our facility. This allows us to experiment with new techniques - keeping us one level above of our competitors. Our foundry casts primarily in ZA-12 and A356 alloys. With travels of 60", 30", 35" xyz, we can machine any casting we produce. Using gravity pour, we hand ladle the molten alloy into the graphite mould. This produces less turbulence, therefore, decreasing the amount of porosity.

We have converted hundreds of complex parts from conventional manufacturing methods to GPM Zinc/aluminum castings. Our total in-house, turnkey capability can help you by providing assistance for concept, design, affordable tooling, precision castings and any secondary machining operations.

Traditional methods for producing high tolerance cast parts require complicated casting processes for investment castings, or expensive tooling and equipment for die cast parts. Zinc/aluminium alloy castings produced with graphite permanent moulds now offer unique opportunities for strength, precision and excellent part finishes. Tolerances of +/- .005” as cast eliminates most of all secondary machining operations. Finishes are achieved similar to that of zinc die castings of 125 micro inches or better. ZA-12’s bearing and weight resistant properties can eliminate bushings, wear inserts and hard coat processing. Tooling cost savings is as high as 50% to 75%. The graphite process also produces text as shallow as 0.010 inches.
