Overview And Working Principle Of Rubber Extruder

Overview

A rubber extrusion machine is a basic equipment in the rubber industry and is one of the key equipment that affects product quality. It plays a very important role in the production of tires and rubber products. The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages.
working principle
The function of the rubber extruder is to use heat, pressure and shear to transform solid plastics into a uniform melt, and send the melt to the next process. Melt production involves the mixing of additives such as color masterbatches, resin blending, and repulverization. The finished melt must be uniform in concentration and temperature. The pressure must be large enough to squeeze out the viscous polymer.
application
The rubber extruder and its auxiliary equipment are one of the most widely used important equipment in the rubber industry. It is mainly used for the extrusion molding of treads, inner tubes, rubber strips, hoses, tapes and other rubber products. It has excellent features such as energy saving, high yield, good plasticization and low temperature rubber compounding, making the extrusion machine more widely available as a new generation of efficient rubber processing equipment. Rubber extruder equipment is widely used in the manufacture of semi-finished products such as pure hoses, tire treads, inner and outer layers of rubber hoses, wires and cables, etc. It can also be used for plasticizing of raw rubber, filtering of rubber materials, metal wire coating, etc.
