Rubber Extrusions

One of the major manufacturing techniques of the rubber and plastics industry is the extrusion process. Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed or drawn through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections and work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish.

Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). The extrusion process can be done with the material hot or cold.

Commonly extruded materials include metals, polymers, ceramics, and foodstuffs.  Some of rubber finish good resulted from extrusion such as silicon tubes / food grade hose, rubber cords, glass rubber seal / window rubber, etc.  Below are some pictures of rubber extrusion.
