Semi-Permanent Mold Castings

The Semi-Permanent Mold Casting process uses the same general procedures as Permanent Mold Casting but in this process expendable cores of sand or other materials are added to the molding process to create a desired shape or an internal passage. In many cases, the practicality of having a solid casting does not exist. Many customers require that a product have passageways for materials to flow through; therefore a method of creating such passageways must be incorporated. In Semi-Permanent Mold Castings a pre-formed core is inserted into the Permanent Mold cavity. The metal flows around the insert and creates the desired shape or passageway. By using a sand core it allows for the easy removal of the insert to create the desired effect
