Permanent mold casting

sand casting, the main difference being that the mold is permanent. Cores are used to create cavities into a product. These can consist of both sand or metal. In the latter case the design should be such that, after casting, the cores can be removed.

A permanent mold is composed of several shapes that together form a closed product cavity. The mold parts are aligned with dowel pins and are held together tightly using a clamp or bracket. The service life of the permanent mold strongly depends on the processed material and the associated temperature.
