The injection molding technology is to heat and plasticize the kneaded rubber into the cylinder through the feeding device, and then, under the push of the screw or the plunger, is injected into the closed mold through the nozzle, and is vulcanized and shaped under the heating of the mold. The equipment used for injection molding is a rubber injection machine, and its working principle and structure are basically the same as those of a plastic injection machine. The working pressure of the injection machine is generally 100 to 140 MPa, and the vulcanization temperature is 140 to 185 °C.
