The machine is used for extrusion of various rubber products and rubber feeding. Structural features: 1.Pin-barrel cold feed rubber extruders are made by the company with introduced technologies. Different extrusion heads are applied to extrude various half-finished rubber products. The machines can also be used to feed rubber to manglers. 2.The barrel is composed of several zones. In the feeding zone, the spiral slots work with the side rolls to enhance feeding capability .In the plasticizing and extrusion zones, different numbers of pins are fitted. 3. The screw is processed and polished with the foreign-made milling machine and is featured by excellent geometric precision. Nitrogenation treatment makes it more wear-resistant. 4.The gears in the reducer are made of alloyed steel, and their teeth are hard. 5.A hot water circulation device automatically controls temperature in each zone. 6.The machine is driven by a DC motor and AC motor.
