Compression Molding for Healthcare & Medical Components

Lowering upfront investment

Compression Molding

Key Benefits:

  • Lower upfront tooling cost
  • Shorter tooling lead time
  • Lower material scrap than injection or transfer molding methods
  • Process suitable for most elastomers and curing systems

Compression Molding Methodology

Compression molding is ideally suited for low to medium volume applications. Complex shapes can be produced with a relatively small investment in tooling compared to transfer or injection molding. A specially weighted and shaped preform of rubber is placed into each of the mold cavities. The mold is then closed, forcing the preform into the shape of the part. The elastomer is held under pressure until the rubber achieves the required amount of crosslinking. Flash is then removed and the parts are placed in an oven for post curing to achieve a fully cured finished part.

Typical Healthcare & Medical Applications

Compression molding is generally used in applications where custom shapes are needed such as diaphragms for respiratory equipment, lip seals for cylinder applications or isolation bumpers used to inhibit vibrations.
