Rubber extruder is a basic equipment in the rubber industry and 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 gone through the stages of 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, etc.

Rubber and plastic machinery and equipment manufacturing industry will compete towards the joint
Initiated by 9 units such as big rubber and plastic, third base machine and honest rubber and plastic, with the participation of 35 enterprises in Dalian, Dalian rubber and plastic machinery association was established. This means that after more than 50 years of development, the rubber and plastic machinery and equipment manufacturing industry in Dalian will move from competition to union. Dalian is the birthplace of China's rubber and plastic machinery and equipment manufacturing industry, the gathering place of rubber and plastic machinery and equipment manufacturing industry in Northeast China, and one of the domestic rubber and plastic machinery manufacturing bases. Since the mid-1950s, Dalian General Machinery Factory, the predecessor of Dalian Rubber and Plastic Machinery Co., Ltd., was ordered to develop and produce rubber and plastic machinery. After more than 50 years of development, Dalian has more than 100 enterprises including scientific research, production and operation, forming a relatively complete product system, and the complete set of capabilities is also constantly improving, which can provide high-level equipment for the rubber industry and plastics industry. Machinery Industry Plastic Machinery Information Network, National Plastic Machinery Standardization Technical Committee and Machinery Industry Plastic Machinery Product Quality Supervision and Testing Center are all located in Dalian. Most of the global standards and industry standards for rubber and plastic machinery are based in Dalian. Dalian's rubber and plastic machinery products are spread across 34 provinces, municipalities and autonomous regions (including special administrative regions) across the country, and are sold to nearly 100 regions on 5 continents, dalian has developed into one of the centers of research, development, production and marketing of rubber and plastic machinery in China. It has unique advantages and development potential in the northeast and even in the whole country.

The car rubber liquid seal is made of binary rubber EPD) material, which has good elasticity and sound drop effect. Since the ladder sealing strip is in the compression open/state during the actual matching process, the sealing strip and the surrounding environmental parts are often in an interference state when designing the structure. The amount of interference and deformation state play a decisive role in the sealing performance of the car. Design engineers usually design and optimize the structure and amount of interference of EPDM rubber strips based on experience. This will greatly reduce the reliability of the design, resulting in frequent problems in the later period and increasing development costs.

Rubber and plastic in rubber and plastic insulation pipe is a general designation. Rubber in rubber and plastic refers to "rubber" and plastic refers to "plastic". Rubber is used more in tires, while plastic is used more widely, such as plastic boxes, plastic bags, etc. Rubber plastic pipe is mainly made of rubber, which is a kind of material. Professionally speaking, it should be a kind of material made and synthesized by using olefin organic gas produced after oil processing and refining as raw material.

Automobile sealing strip production line
Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, sunroofs, engine boxes and backup (luggage) boxes. It has the functions of sound insulation, dust prevention, water seepage prevention and shock absorption. Maintain and maintain the small environment in the car, thereby playing an important role in protecting the occupants, electromechanical devices and accessories in the car. With the development of the automobile industry, the importance of the beautiful, environmental and comfortable functions of the sealing strip is becoming more and more obvious. Shanghai Baodi is engaged in the production of such machinery and equipment, and its machines are efficient and stable.

Automobile sealing strip production line equipment function
(1) Extrusion part: For the production of profiles with small cross-sectional dimensions like sealing strips, single-screw extruders or co-extrusion are generally selected for molding and processing to avoid waste of production resources and energy. The choice of single-screw extruder depends on two main factors: one is the size of the cross-sectional size of the product; the other is the output requirement. The greater the extrusion output, the larger the screw diameter; profile cross-sectional area (cross-sectional size), the larger the screw diameter.
