Custom rubber molding services from Winners Rubber include rubber injection molding, rubber compression molding, and rubber transfer molding for quality molded rubber parts.
Rubber Injection Molding
Rubber Injection Molding is the most efficient way to mold rubber in most cases. There are many advantages to Rubber Injection Molding:
- Quicker cycle times
- Custom shapes with little flash
- Support for wide range of durometers
Rubber Compression Molding
Compression molding involves using rubber compound or mixed raw material and making “pre-forms” that are in the shape of the end product. These shapes are then loaded, typically by hand, into an open mold. The mold is closed, the rubber cured, and then demolded. The advantages of rubber compression molding include:
- Lower tooling costs
- The quantity required is very low.
- The part cross-section is very large and it requires a long cure time.
Rubber Transfer Molding
Rubber transfer molding places uncured rubber into part of a mold called a pot. When the mold is closed, a “plunger” compresses the rubber in the pot and forces it through holes to fill the part cavity. The advantages of rubber transfer molding include:
- Higher production efficiency
- Support for precise tolerance requirement
- Suitable for middle to high volume production
