What Is Rubber Extruder Industry’s Situation?

The annual output of rubber extruder in my country is nearly 800, and there are about 50 manufacturers, mainly in Qingdao, Guilin, Inner Mongolia, Shanghai and other places. Although there are many rubber screw extruder manufacturers in China. However, there are only 4-5 companies with development and design capabilities and considerable influence in the industry. In the mid-1980s, China began to contact and use the triple-composite extrusion technology and double-composite extrusion technology of Bet-storff Company and Troe ster Company. An Inner Mongolia Co., Ltd. conducted technical exchanges with many foreign companies. On the basis of absorbing foreign advanced technology, it developed and produced a variety of specifications of pin-type cold feed composite extruders, which made the composite extrusion equipment domestically made and The technology has reached a relatively mature level. in recent years. The company provided *200/2500 double compound pin cold feed extruders for Beijing Tire Factory and Hefei Giti Tire Company. 1 2 0/1 5 0/1 2 0 Three composite pin type cold feed extruders, and provide a number of different specifications of pin type cold feed composite extruders for Vietnam and Taiwan-funded tire factories.

In the production of sealant strips, three-composite heads and four-composite heads have also developed rapidly. Most of the composite heads of the sealant strip production line introduced earlier in our country are equipped with shearing heads, and the head structure is relatively complicated. After years of development, the three-composite and four-composite heads used are quite simple in structure and have good use effects. Then use the shear head. With the development of domestically produced composite extrusion equipment, the composite extrusion technology and production process will develop rapidly. Inner Mongolia Fute Rubber & Plastic Machinery Co., Ltd. independently designed and produced a pin-type cold feed extruder with an "L" type roller head. The production process of rubber film covering the conveyor belt and the production of radial tire inner liner film Get applied. Its biggest feature is the integration of many advantages of the calender and extruder, the air tightness of the extruded film is good, the production process is simplified, the production equipment is reduced, a lot of energy consumption is reduced, and the quality of the production is improved.

According to reports, some domestic composite extrusion equipment can completely replace imported equipment. The medium 150 cold / ~ 250 hot dual composite extrusion unit developed by Guilin Rubber Industry New Technology Development Industrial Corporation uses a new structure screw, which greatly improves the rubber conveying capacity, and the extrusion volume reaches 4200kg/h; extrusion is below 11.00 The tread speed of the specifications is between 16-22m/rain, which is about double the index of most similar imported equipment. The ~1 20/medium 200/medium 250 cold feed triple compound extrusion unit developed by it became the first triple compound extrusion equipment for all-steel tire production in China. China Chemical Industry Guilin Engineering Company has also successfully developed a four-composite extrusion unit, which has reached and approached the advanced level of foreign countries, and has been used for sidewall extrusion of radial tires produced by Michelin. The unit is worth ten million yuan and is a production line specializing in the production of various high-end radial tires. This set of equipment is a behemoth with a length of one hundred meters, and only one nose of the unit weighs 23 tons. Only a few manufacturers in the world can provide similar products. The localization of advanced equipment is conducive to the promotion of new equipment and technology, improves the level of enterprise equipment, and promotes production development. Especially due to the rapid development of radial tire production in my country and the advantages of pin-type cold feed extruders, the pin-type The popularization and application of cold feed extruder has greater advantages, becoming a replacement product of hot feed extruder and ordinary cold feed extruder, providing broad development and application prospects for pin-type cold feed extruder.
