An injection mold is used in production tooling process in order to produce plastic molds that come from plastic materials. The process is better known as injection molding. It starts when the thermoplastic or thermosetting plastic materials are fed into a barrel usually heated and mixed then forced into a cavity where it is left to cool. Cooling the materials will lead to hardening in order to follow the shape of the mold cavity.

In order to understand the process better, it is deemed fit to characterize the steps involved. It makes use of a ram or other screw-type plungers in order to make sure that the molten plastic is placed properly inside the mold cavity. Once it follows the shape of the mold, it may result to either of two forms open or solid ended shapes. From the production tooling, it will often be noticed that a parting line or gate mark may be seen. Furthermore, pin marks after ejecting the output may be visible.

Injection molding is widely used many different fields. If you also want to use the injection molding, you should know more things about it, and you can read our articles.
