Rubber Injection Molding
Rubber Injection Molding
Rubber injection molding feeds uncured rubber from a hopper into heated barrel. The elastomer is then pushed by a screw-type plunger into a heated chamber. This material flows through a gate and runner system into mold cavity. The mold remains at the proper temperature until the rubber is cured.
The advantages of rubber injection molding include:
- Quicker cycle times
- Custom shapes with little flash
- Support for wide range of durometers
Rubber Injection Molding Steps:
- Material in injection unit ready for injection into cavity
- Material is injected from injection unit through runner system & gates into cavities.
- Parts (material) are cured in mold until the cure process is completed.
- Molded rubber parts are removed from mold and the process is ready to begin again.
