The first rubber molding process, rubber compression molding, is ideal for low to medium volume production of rubber products. Compression molding is a widely used economical production method for low volume production of medium to large parts.  It is the best rubber molding process for materials with a high cost and applications that demand extreme hardness.

Rubber compression molding can produce a diverse range of custom rubber molded components and the affordable production of large, intricate products. It is often used to produce environmental seal products such as rubber o-rings, seals, and gaskets.

The Rubber Compression Molding Process

The rubber compression molding process uses a preformed piece of uncured rubber that is placed in an open mold cavity. The mold is preheated to an elevated temperature.  As the mold closes in the press, the material is compressed and flows to fill the rubber mold cavity.

The combination of elevated temperatures and high pressures activates the vulcanization process and curing of the rubber compound. Once an optimal cure is reached, the part hardens and cools then the mold is opened and the final part removed.  The next rubber preform is inserted into the mold and the cycle repeats.

The basic compression mold is usually a two-piece construction consisting of a top and bottom plate. Half of the part cavity is usually cut into each plate of the mold.  A trim area is created by grooves cut around each cavity which allows the excess rubber to flow out of the cavity. Compression molds are typically secured between heated press platens.  The molded parts require trimming to remove the groove overflow.  An additional bake cycle may be required for partially cured parts.
