Injection Rubber Moulding

Rubber injection moulding rubber has its roots in the moulding of plastics. In the 1960's, engineers developed a way to use the same principles in moulding plastics to mould rubber, making rubber injection moulding one of the most efficient rubber manufacturing processes. The rubber injection moulding process works by significantly heating the rubber and using a very high pressure to inject the rubber compound in to the mould.

From there it is injected through the runner system in the tool into the cavities of the closed hot mould. The combination of pressure, temperature and time facilitates the crosslinking of chemical bonds commonly referred to as vulcanization. Process parameters are usually programmed into the press to control temperature, volume and rate that compound is injected into the mould cavities
