Rubber injection molding
The rubber injection molding process involves pressing a rubber compound into a mold cavity under high pressure. We recommend rubber injection molding as one of the most efficient and repeatable methods of manufacturing molded rubber products.
The practice of rubber injection molding began in the mid-1960s and follows a process for molding plastics by heating rubber and placing it under significant pressure to form a rubber part within a mold cavity.
First, the uncured rubber material is fed into the syringe barrel, which is then heated by an auger in the temperature-controlled barrel. The rubber material is then injected into the cavity through an injection molding machine, and as the material cures in the heated mold, the auger turns to refill the barrel. Once the mold is opened, the newly formed part can be removed and the injection molding machine can then form another part.
