Pin barrel cold feed rubber extruder is mainly used for extrusion of tire tread, inner tube, rubber pipe and tube, rubber strip and belt etc. 1.      The barrel is composed of several zones. In the feed zone of barrel with the spiral slots. In the plasticity and extrusion zone different number of pins are fitted which enhance mixing and plastic capacity for extrusion material. 2.      The screws and barrels made of high quality alloy steel with nitrogen hardening makes it more wear-resistant and more corrosion protection. 3.      According to requirement of process the temperature in each zone may be automatically probing and control for each zone with good sensitivity. 4.      The extruder is driven by a change frequency motor or D.C motor, which achieve continuous and smooth speed regulation. 5.      Owing to the screw with higher efficiency and pin-barrel are fitted. The extruders include better mixing and plasticity result, higher extrusion, capacity, and lower temperature of the outgoing rubber. So that the output of production and the quality of product are raise.
