Custom Rubber Extrusion Rubber Round Sealing Strip

Rubber extrusion is a process used to manufacture rubber products. The process uses an extrusion machine to force synthetic or natural rubber material through a shaped die under high pressure. The material used is typically soft, un-vulcanized rubber. The process shapes the workpiece in a soft, pliable state, after which it is vulcanized to harden the workpiece into a usable final product.

A rubber extruder machine is composed of two primary parts. A heated shearing screw pushes the raw material along a conveyor as compounds are fed into the extruder. As the material moves along the conveyor, it is heated and softened to make it pliable. The softened material is pressurized by the shearing screw and forced into the die where it takes its final shape
