Semi-Permanent Molding

General Aluminum Manufacturing

The Semi-Permanent Mold process requires both metal dies and sand cores to create internal cavities for alloy flow for specific internal features. This method enhances product strength as compared to sand casting but also allows intricate passages to be created. The benefits of this process are that it allows flexibility of the internal design not only during the development cycle, but also allows for different configurations of internal cores and passages. Typical applications include Transmission Pump Housings, Rotor housings, Control Arms, and Water Inlets.
