In the rubber extrusion process, an extruder takes rubber material and softens it through heating, pressurizes it and forces the rubber through a die, which gives the rubber its profile. The material then goes through a curing process (steam or continuous curing).

An important factor to consider for rubber extrusion is accurate material selection for an application. Mechanical and physical properties like impact and tensile strength, flexibility, hardness and corrosion resistance vary in different materials so the correct choice of materials is necessary to ensure it is well suited for a specific design application.
