   The molten plastic utilized for injection-molded products is produced by melting small plastic pellets, that happen to be fed into an injection machine heating the pellets to a molten or liquid form.

   As soon as the now molten plastic pellets reach a predetermined temperature the semi liquid is forcefully injected in a mold. The velocity and pressure on this process is controlled with a hydraulic cylinder that, once engaged, forces the liquid plastic in to the mold.

   In "dwell" phase in the plastic injection molding process, the plastic is left inside the mold to ensure that it entirely fills the mold and then in a position to cool to the point where it solidifies and also the desired object is produced. Then it is ready for secondary processes as decoration, sub assembly, or shipment.
