The rubber extruder is the basic equipment in the rubber industry. It plays a very important role in the production process of tires and rubber products and is one of the key pieces of equipment that affects product quality. The development of rubber extruder has experienced plunger extruder, screw-type hot feed extruder, ordinary cold feed extruder, main and auxiliary thread cold feed extruder, cold feed exhaust extruder, Pin cold feed extruder, compound extruder and other stages.
In the plastic extrusion molding equipment, it is usually called the main machine, and the subsequent equipment that is matched with the plastic extrusion molding machine is called the auxiliary machine. The main engine of the plastic extruder is the extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipe, film, holding material, monofilament, flat wire, strapping, extruding net, sheet, profiled material, pelletizing, cable coating, etc., to form various plastic extrusion machines. Out of the molding production line, various plastic products are produced. Therefore, plastic extrusion molding machinery is one of the widely used models in the plastic processing industry, no matter now or in the future.
The difference between a rubber extruder and a plastic extruder is firstly reflected in the temperature during use. The operating temperature of the rubber extruder is between 40-90 degrees Celsius; the operating temperature of the plastic extruder is 150-25 degrees Celsius; secondly, the two The screw ratio of the rubber extruder is 4--8:1; the screw ratio of the plastic extruder is 10-20:1.
