Rubber Injection Molding is a process in which strips of rubber materials are fed into injection molding machines and cured. In most cases, it is the most efficient way to mold rubber. Rubber injection and injection-transfer molding start with more efficient material preparation. The material is mixed, typically in 500-pound batches, and then stripped immediately after being mixed, into continuous strips measuring approximately 1.25" wide and 0.375" thick. This strip is fed into a screw on the injection molding machines, which charges a barrel with a pre-defined amount of material. When the mold is closed, the material in the barrel is injected into the mold cavities and cured.
