Precision casting, also called investment casting, is a lost wax casting process widely used for producing ferrous and nonferrous metal parts. Unlike other casting processes, precision casting produces net shape parts with excellent surface finish and dimensional accuracy. This manufacturing process is ideal for applications that have relatively low production quantities (100 to 10,000 pieces) or rapidly changing product designs.

With precision casting, we can cast nearly 200 alloys. These metals range from ferrous-stainless steel, tool steel, carbon steel and ductile iron-to non-ferrous-aluminum, copper and brass. When cast in vacuum, super alloys are also available. The only process that matches this breadth of materials is machining, but it cannot produce the complex geometries that precision casting can deliver.
