Rubber compression molding is an excellent choice for producing rubber components in low to medium volumes. This widely adopted and cost-effective technique is particularly well-suited for the creation of medium to large parts, especially in cases where high-cost materials and extreme hardness are required.
Rubber compression molding can produce a wide variety of custom rubber molded components, making it a cost-effective solution for creating large, intricate products. This process is frequently used to manufacture environmental seal products such as rubber O-rings, seals, and gaskets, ensuring high performance and durability.

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.

Advantages of Rubber Compression Molding
Rubber Compression Molding offers advantages over other methods by providing:
- Tooling savings
- Short setup time (saves on short production runs)
- The capacity to process stiff, high durometer materials
- Ideal for large parts that require a long cure time
- Maximized cavity count
- Ideal for low volume part requirements
- Ability to process most elastomers and cure systems
Disadvantages of Rubber Compression Molding
- Longer cycle times
- Mid-range precision and consistency
- Labor intensive
