CNC Mould Making

CNC Mould Making

CNC mouldmaking is the process of manufacturing precision molds for plastic injection molding, die casting, blow molding, and other forming processes using Computer NumericalControl (CNC) machines. This technology uses automated, computer-controlled cutting tools to carve and shape mold components from metal blocks with high accuracy and repeatability.
