ABOUT Rubber Injection Molding
Technology: Rubber Injection Molding Services are manufacturing services used to mold rubber parts using high pressure injection molding machines. Rubber Injection molding uses ribbons of uncured rubber which are fed into a feed screw barrel which plasticizes the ribbon. It is then injected into a closed two-piece mold where it cures and is then ejected. In the liquid injection molding process, liquid silicone rubber is mixed with a curing agent which is injected cold into the mold where it is heated and cured under pressure.Good for complex partsThe process lends itself to automationNo need for preformsElimination of flash
Advantages: Rubber injection molding services provide low per piece costs in high volume runs of rubber parts.
Limitations of Rubber Injection Molding ServicesSignificant upfront costs in mold making compared with other molding methodsDemolding injected silicone rubber can be difficultEconomical mainly for high volumes of precision parts
Applications: Rubber injection molding services provide a high volume alternative to other molding methods forMedical devicesElectrical bushings/insulatorsGaskets, grommets, bellows
