Manufacturing Processes

Compression Molding

Compression molding is a widely used manufacturing process for producing custom O-rings and rubber products. In this process, a pre-measured amount of rubber compound is placed in a heated mold cavity. The mold is then closed, and pressure is applied, forcing the rubber to fill the cavity and take the shape

of the desired O-ring. Once the rubber has cured, the mold is opened, and the finished O-ring is removed. Compression molding is known for its cost-effectiveness and ability to produce O-rings with complex shapes and features. However, it may have longer cycle times compared to other molding methods.

Injection Molding

Injection molding is another common manufacturing process for producing custom O-rings. This method involves heating a rubber compound to a semi-liquid state and injecting it into a mold cavity under high pressure. The rubber cools and

solidifies within the mold, taking the O-ring shape. Once fully cured, the mold is opened, and the finished O-ring is ejected. Injection molding offers advantages such as high production rates, precise dimensional control, and reduced waste compared to compression molding. However, it may require higher initial tooling costs and may not be suitable for all rubber compounds or designs. Custom O-ring manufacturers can use compression and injection molding processes to create O-rings tailored to specific application requirements, ensuring optimal performance and quality.
