In the latter part of the 20 th century, experts introduced techniques for rubber injection molding that were similar to plastic molding. In almost all rubber injection molding procedures, rubber is heated at extremely high temperatures and injected into molds. Given below is a detailed description of how rubber is molded. Preparation of materials Synthetic or natural rubber is mixed with appropriate additives to satisfy the specifications mentioned for future design use. The synthetic rubber is called elastomer and the rubber obtained after mixing is called thermoset elastomer. This thermoset elastomer is now fed in the form of strips into the screws and barrels where the rubber is heated at temperatures that are slightly lower than that of the considered rubber mold. Injection of the rubber Now the compounded material is injected via the channels of the tool to finally reach the cavities of the hot mold that is closed. In this stage, the compounded material is subjected to a ...

A rubber seal is one of the most important rubber components used in the industrial applications. There is wide variety of rubber seals available depending upon the materials used in making them. Each of these materials is useful for specific applications and come with their own advantages and disadvantages. The major types of rubber materials that are used for making rubber seals are as follows:   ·          EPDM - EPDM (Ethylene Propylene Diene Monomer) is a kind of synthetic rubber that has versatile uses. Since this kind of rubber can withstand weathering, they are widely used in seals that are used for the outdoors applications. EPDM seals are lightweight and easy to die cut. ·          Silicon - Silicon is one of the most popular kinds of synthetic rubber that is used for making seals. Silicon can be used for both hot and cold applications. It makes for a great choice for molded seals. · ...
