Rubber Injection Molding Process in 7 Steps
Rubber Injection Molding Process in 7 Steps
The 7-step rubber injection molding process: material preparation, mold design, injection, vulcanization, demolding, quality control and packing – for accurate, consistent rubber parts.
Rubber injection molding in 7 steps
Rubber injection molding pumps rubber into a closed mold under high pressure for accurate, consistent parts at high output.
1. Material preparation: natural or synthetic rubber (EPDM, NBR, silicone) compounded with additives, pigments and accelerators.
2. Mold design: steel or aluminum mold optimized for injection, with sharp detail and little flash.
3. Injection: preheated rubber is pushed by screw or piston into the cavity.
4. Vulcanization under set temperature and pressure.
5. Demolding and deflashing.
6. Quality control of size, color, elasticity and strength.
7. Packing and delivery.
The mold drives most of the outcome. Nhan Loc Phat designs and builds rubber injection molds with CNC and EDM machining, free engineering advice and ongoing support.
