FINISHING

Finishing

Our finishing process includes taking cooled, molded cast assemblies and preparing them for use. Castings are separated from the gating/risers and all flash and parting line metal is removed.

Depending on the casting type (air set/no-bake, green sand, or perm mold/gravity-fed die cast) finishing may involve several steps. We start the finish process with grinding unfinished edges from coarse to fine and add on levels of polishing, grinding, and shot blasting until the castings are at the desired finish.

Our surface finish leaves an excellent base for any secondary processing such as any additional machining, heat treating, plating, powder coating, zinc plating, anodizing, or traditional wet painting.
