The pin-type cold feed rubber extruder is commonly applied in the manufacturing of products having high requirements on quality like rubber hoses, rubber cables, and other similar items.
The barrel of the pin-type rubber extruder is uniformly inserted with multiple rows of pins. As rubber is fed into the barrel through the feeding system, the pins inside the barrel enhance the mixing speed of the rubber, increase the density of the rubber, and reduce the mixing time.

Hot feed straining extruder requires the rubber material fed into it to undergo hot refining, with uniform and stable feeding at a constant speed. The material temperature should be maintained between 50 to 70 ℃. This type of rubber extruder needs to be used together with an open mixing mill, where the material is directly fed under the open mixing mill to achieve simultaneous straining and sheeting processes.
