Description of the Rubber Injection Molding Process:
The process of rubber injection molding begins with an uncured rubber ribbon stock. This is fed into a rotating screw of the injection unit. Controlled amounts of material are then pulled into the unit where the material is plasticized to a specific temperature. Next, the rubber is injected into the mold through a runner and gate system, exposing it to high pressure and temperature. This activates the cure system in the rubber compound, vulcanizing the rubber. The cycle time is set to achieve the desired curing level, and once the cycle completes, the parts are removed to prepare for the next cycle.
