The manufacturing processes of injection molding and die casting are widely used in the production of parts. In order to choose the right process for your products, you should know the differences between injection molding and die casting.
Material
One difference between injection molding and die casting is the material used.
Injection molding uses molten material, mainly plastic. This is injected into a mold (the injection mold). There, the material solidifies, takes on the shape of the cavity and is then ejected from the mold.
Polypropylene (PP) is one of the suitable materials. It is one of the most widely used injection molding plastics, often used for packaging. Polypropylene can be welded and has very good chemical resistance.
