Extrusion: Definition, types and application - Engistudies

Difference between extrusion and injection molding. Extrusion is a continuous process which involves squeezing metal through a die. It is intended for making continuous lengths of desired cross sections. Whereas injection molding is a method in which metal is injected into a mold and after cooling it is removed from the mold. It is a cyclic process.

Extrusion vs. Plastic Injection Molding

During the extrusion molding process plastic material (whichever type you choose) will be melted and placed into the die under pressure. In this case, however, the die will eject the material and it will take on the form of said die. This is done in a continuous manner and is sometimes considered to be a bit faster than standard injection molding.
