  With the emergence and wide application of rubber extruder machine, the application range of hot feed extruders is gradually shrinking. Rubber extruders have developed from hot feed to cold feed, and cold feed pin extruders have become the mainstream of development. Pin extruders have been widely used in China's rubber industry, involving tire treads, radial tire sidewalls, bead rubber, various hoses and inner lining films. The machines used are imported and domestically produced. The screw diameter is 85～250mm, and the ratio of length to diameter is 12～16. The pin-type cold feed extruder has many advantages over the hot feed extruder and the ordinary cold feed extruder. It has been widely used in the production of rubber industry in my country, and its use has been continuously expanded. The pin-type cold feed extruder introduced in the early domestic period is mainly used in the rubber core and encapsulation production process of radial tire tread rubber extrusion and rubber tube production. Most of the semi-steel and all-steel radial tire treads are produced by pin-type cold feed extruders. In the production process of bias tires and other rubber products, many manufacturers have adopted pin-type cold feed extruders. In the rubber industry, the traditional production process is that the extruder is used as the molding extrusion process equipment. The pin-type cold feed extruder has been widely used for steel wire and fiber cord calendering due to its large extrusion capacity and good plasticizing effect. Glue supply for machine and inner liner film calender. The pin-type cold feed extruder is also popularized for rubber strainer, and has been well received by users.

  The pin-type cold feed internal compound extruder has also been widely used in the production of radial tires, and has become the key equipment for the production of radial tires. Although some companies still use the out-of-machine compound extrusion process in production, with new technologies and new With the improvement and renewal of technology and the development of market economy, the old production technology and equipment will be eliminated. The internal compound extruder is the inevitable development direction of compound production technology.

  However, in China's rubber industrial production enterprises, hot-feed extruders still account for a large proportion. According to incomplete statistics, the hot-feed extrusion production process that uses an open mill to supply rubber accounts for about 70% in my country. Many old rubber production companies in China use extrusion equipment from the 1950s, and the technology and equipment are backward. Some companies believe that the old extrusion equipment has certain advantages, such as good dispersion, good operability, and skilled operators. However, the advantages of pin-type cold-feed extruders are greater than those of hot-feed extruders. Out. The pin-type cold feed extruder represents the development direction of rubber extruders and has great development potential. It can be seen that there is still a lot of room for the technical transformation of the extrusion process in my country's rubber production enterprises to further promote the use of pin-type cold feed extruders.
