What is injection molding?

Injection molding is the process of forcing melted plastic in to a mold cavity. Once the plastic has cooled down, the part can be ejected. It is useful when the parts are too complex or cost independent to the machine. With this process, lots of parts can be made at the same time and out of the same mold.
