Rubber Injection Parts

Rubber Injection Parts The molding of rubber and elastomeric compounds is done by forcing the material into a shape by using heat and pressure. Rubber can be molded by compression, transfer and injection methods. Injection or liquid injection molding is a process of molding rubber parts.

The process
In this process, a part of the configuration is cut into a series of metal plates that are stacked to form the mold. A plate is added where the injection nozzle introduces material into the sprue system and from there into the cavity. To form the rubber component, the heated mold plates are closed and the material is injected into the cavity through the nozzle of the injection. This can be screw system, ram system or combinations of both. The uncured rubber is then squeezed through the system whether hot or cold into the cavity which forms the rubber component. The injection system is set up in such a way to deliver amounts of material to the cavity, and the sprue system is set up so that no excess material is lost.

Rubber injection molding lead to the formation of various rubber injection parts which are used in diverse markets including:
