What is Rubber Extrusion?

Rubber extrusion is the process of turning raw rubber materials into varying lengths with constant cross-sections, as can be seen in Figure 1.

Although there are different types of extruders, which is shown here, the process is the same – soft, un-cured synthetic or natural rubber is loaded into the extruder and forced, under high pressure, through a shaped die. This die forces the rubber into the desired cross-section. Then, the extrusion will typically need to be cured or vulcanised to be rendered usable.
