Production methods

Compression molding is dependent on compressive force and heat to form uncured rubber in the desired shape and size. The process involves inserting unvulcanized rubber material into the mold. Inside the mold, the material is heated and hardened, which makes it possible to maintain the mold even when it is removed from the mold.

Compared to other casting methods, compression molding has a number of advantages. For example, the lowest tool cost, fastest lead time, easiest input for prototyping. However, it is limited in the precision and complexity that can be achieved.

Injection molding uses high pressure and heat to force rubber into a mold. The material in this operation is heated until it reaches a plastic state and then injected under high pressure into the mold. Inside the mold, the material is exposed to high heat and pressure, which initiates the vulcanization process.

This process provides good precision, consistency, design complexity and efficiency. However, these benefits come with a higher price tag. Since the mold costs are high, the process is better suited for high volume parts.
