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
