In the rubber industry, compound extruders are mainly used for the extrusion of composite tire treads, automotive sealing strips, colored cycle tire treads, rubber hose compounding, rubber-plastic composite extrusion, and multi-layer co-extrusion of rubber sheets, etc. The compound extrusion production process is an advanced technology in the rubber industry. According to different performance requirements of the products, it can use rubber compounds with different formulas and properties to produce products that both save materials and meet various performance requirements through compound extrusion equipment.

Classification of Rubber Compound Extruders

By number of extruders: dual-compound extruder, tri-compound extruder, four-compound extruder;

By feeding form: pin cold-feed extruder compounded with pin cold-feed extruder, hot-feed extruder compounded with pin hot-feed extruder; hot-feed extruders are divided into cylindrical screw and conical screw; by head form, they are divided into gantry (door-type) locking and hydraulic tie-rod locking.
