A rubber injection molding machine is a specialized manufacturing equipment that heats and liquefies uncured rubber, then injects it under high pressure into a mold cavity to create precise, shaped rubber parts, with the final product formed through a curing process within the mold, allowing for mass production of consistent rubber components with intricate details; essentially, it functions like a standard injection molding machine but is specifically designed for rubber materials, utilizing specialized heating and pressure controls to achieve proper vulcanization.
