Precision CNC Machining

Graphite Permanent Mold Technology (GPMT) began in the late 1970’s and our professional team has been working with this technology since 1984. With this expertise, Forest City Castings can provide you with a raw casting from a 3D electronic file in an industry leading time frame.

The graphite system eliminates the expense of metal tooling. Tooling is computer generated and fed directly to our high speed CNC Mills, where the graphite tool is cut. The speed in which graphite can be machined allows for rapid engineering changes, often in hours or days, as opposed to weeks or months like some alternative methods. These features allow the graphite system to exceed the potential of sand casting and to produce parts that rival those produced in a die-casting mold for only a fraction of the tooling price.
