Silicone rubber extruders are fundamental equipment in the rubber industry and rank among the key machines that influence product quality, playing a crucial role in the production of tires and various rubber products. The evolution of extruders abroad has progressed through several stages: plunger-type extruders, screw‑type hot‑feed extruders, conventional cold‑feed extruders, twin‑screw cold‑feed extruders, cold‑feed vented extruders, pin‑type cold‑feed extruders, and composite extruders. Silicone rubber extruders are typically classified according to whether they employ hot or cold feeding. In hot‑feed extruders, the compounded rubber is heated by mechanical action in an open mill; the heated rubber strips are then cut off and continuously fed into the extruder. By contrast, cold‑feed screw extruders receive room‑temperature rubber strips. Extruders are also frequently categorized based on whether they are equipped with venting capabilities.
The silicone rubber extruder is a fundamental piece of equipment in the rubber industry and one of the key machines that significantly influence product quality, playing an indispensable role in the production of tires and rubber goods. Internationally, the development of rubber extruders has progressed through several stages, including plunger-type extruders, screw‑type hot‑feed extruders, conventional cold‑feed extruders, twin‑screw cold‑feed extruders, vented cold‑feed extruders, pin‑type cold‑feed extruders, and compound extruders.
Silicone rubber extruders are typically classified as either hot-feed or cold-feed machines. In a hot-feed extruder, the compounded rubber is heated by the mechanical action of an open mill; the heated rubber strips are then cut off and continuously fed into the extruder. In a cold-feed screw extruder, room‑temperature rubber strips are fed directly into the extruder. Rubber extruders are also often categorized according to whether they are equipped with venting capabilities.
