Process Introduction

Typical rubber parts are made by compression vulcanized molding. First a piece of raw rubber compound is placed inside a split metal mold. THen the mold is closed under pressure and is heated to a high temperature typically at 170 ˚C for 10 minutes. During this process the raw and inelastic rubber compound will adapt to the mold cavity to form the desired shape, then cured into a solid elastic rubber part.

The curing process is called vulcanization, a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon to carbon bonds. The end result is that the springy rubber molecules become cross-linked to a greater or lesser extent. This makes the bulk material harder, much more durable and also more resistant to chemical attack. It also makes the surface of the material smoother and prevents it from sticking to metal or plastic chemical catalysts. The vulcanization process is a progressive reaction and is therefore taking a specified time.
