- Compression Molded Gaskets: Compression molding is cost-effective because of lower mold costs and less waste per part. It is widely used for gaskets that don’t require extremely close tolerances or fine finishes. It is especially useful for larger or bulky gaskets.
- Transfer Molded Gaskets: Transfer molding is similar to compression molding, except that the rubber is forced into the mold using a piston. The initial tooling is more expensive and takes more time to build than with compression molding, but shorter cycle times and better product consistency may make it a better choice for longer runsor products that need to meet closer tolerances than possible with compression. It is considered the ideal process for rubber-to-metal molded parts.
- Injection Molded Gaskets: Injection molding is ideal for large product runs because of faster cycle times, and for gaskets that need to meet close tolerances because of exceptional consistency. Because they can be made virtually flash-free, injection molded gaskets often require no additional finishing work. Injection molding is best for smaller, more intricate parts.
