The main advantage of die casted aluminum parts with CNC machining is that there is almost no waste of raw material. Usually, the shape of the part is final when it comes out of the mold. Only some features need to be machined. After injection molding of the aluminum parts we tap threaded holes, machine some faces to remove draft angles and drill holes. These are small machined features that add a little to the unit cost compared to fully machined components.
A disadvantage of injection molded aluminum parts is that they can not be anodized. When anodizing such parts, the structure of the material is too porous and the result is ugly. Therefore, we advise to do powder coating for aluminum casted parts.
It is possible to obtain wall thickness of 1.2 millimeters on relatively small parts.
