Rubber extruder is a basic piece of 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 affect product quality. The development of rubber extruder has experienced plunger extruder, screw type hot feed extruder, ordinary cold feed extruder, main and auxiliary screw cold feed extruder, cold feed exhaust extruder, pin cold feed extruder, compound extruder and other stages. So, what is a plastic extruder, and what is the difference between the two?

The plastic extruder is usually referred to as the main machine in the plastic extrusion molding equipment, and the plastic extrusion molding machine with its supporting follow-up equipment 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 pipes, films, holding materials, monofilaments, flat filaments, packing tapes, extruding nets, plates, profiles, granulation, cable wrapping, etc. to form various plastic extrusion machines. Out of the molding production line, the production of various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used models in the plastic processing industry, now or in the future.

The difference between a rubber extruder and a plastic extruder is first 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; followed by two. The screw ratio of the rubber extruder is 4--8:1; the screw ratio of the plastic extruder is 10-20:1.
