Compression Molding | Custom Compression Molded Products

At Qualiform, we consider compression molding one of the first rubber molding processes.  Compression molding is a common process for thermoplastic stock shape materials.  Qualiform offers numerous rubber materials to choose from.  After the choice is made, we place the material in a mold cavity. Imagine a waffle iron, the shape takes form after we apply heat and pressure!

When to Use Compression Molding

Qualiform offers multiple types of custom rubber molding.  Our team of technical experts can help choose the process that’s best for your application.  When it comes to compression molding specifically, it is often the chosen method for economical production.  Compression molding is best for low to medium production as well as low volume production for medium to large parts.  It is also the best rubber molding process for materials with a high cost and applications that demand extreme hardness.

The compression process is capable of producing a diverse range of precision rubber components and the affordable production of large, intricate products.  Common uses include the production of environmental seal products such as rubber o-rings, seals and gaskets.

Pros of Rubber Compression Molding

  • Tooling costs are comparatively low
  • Low residual stress left in stock shape
  • Short setup time — saves on short production runs!
  • Processes stiff, high durometer materials
  • Ideal for large parts that require an extensive cure time
  • Maximization of cavity count
  • Ideal for low volume part requirements
  • Ability to process most elastomers and cure systems

Cons of Compression Molded Rubber

  • Longer cycle times — not ideal for large volume
  • Mid-range precision and consistency
  • Labor-intensive process
