China's plastic machinery will gradually reach the international level
In recent years, China's plastic machinery technology progress is manifested in the speed of development of new products and new technologies, and the starting point is higher. The main way is to introduce and digest foreign advanced manufacturing technologies. The development of the international market is also an important symbol of the development of China's plastic machinery. One-third of the enterprises have exported their products. The export volume has accounted for about 30% of the domestic sales, and the export growth rate has reached 20%. Taking pipe equipment as an example, the first aluminum-plastic composite pipe production line was introduced in the mid-1990s. There are more than 50 manufacturers producing the equipment in five years. The key technologies such as welding and compounding of aluminum pipes have been obtained. Better solution, the integrity and advancement of most products have reached the international advanced level. In the same period, the development of steel-plastic composite units, gas PE pipe units and other advanced equipment, and solved some key technologies, such as high-speed and high-efficiency single-screw machine for medium and high-density PE processing; good mixing effect, short residence time, High-precision die with no traces and advanced configuration, cooling, traction, cutting, thickness measurement and other configurations. In recent years, domestic extruders have also developed to high torque, high speed and high efficiency, and domestically produced extruders have also adopted advanced separation screws and slotted barrels. The machine heads are generally popular internationally. Basket heads and plate heads suitable for polyolefin processing, programmable circuits and LCD touch screen industrial computers have also been matured. The plastic film processing equipment has been gradually popularized by the manufacturing technology of the spiral head. The superimposed head has been promoted and applied. The multi-layer co-extruded film has reached 5 layers, the geomembrane has adopted the internal cooling technology, etc., and the width of the co-extruded cast film has reached 2 meters. The second approach is to strengthen the development of intellectual property technology through technological innovation. Professor Jiang Bo of Beijing University of Chemical Technology and Beijing Fengji Plastic Machinery Co., Ltd. have successively developed a grinding disc type mixing extruder, which improves the mixing efficiency of materials such as fineness and dispersion and expands the processing materials compared with traditional mixing equipment. The range has significant advantages for processing composite materials such as magnetic and nano. The steel-plastic composite profile extruder production line developed by Beijing Jiancheng Machinery Co., Ltd. has solved key technologies such as compounding, foaming, co-extrusion and cutting. Shanghai Jinwei Extruder Manufacturing Co., Ltd. has developed a PET/GPET co-extrusion line with a width of up to 2 meters. The improvement of the level of plastic machinery and equipment has also been widely recognized in the complete set of equipment. Especially in extrusion molding, the concept of main and auxiliary machines has been deeply rooted for many years. Most manufacturers only provide main engines, and the ratio of main and auxiliary machines is out of balance. This situation has changed a lot. At present, most extruder manufacturers can Provide a complete set of extrusion lines and even undertake turnkey projects. Aluminum profile, also known as aluminum extrusion, is a process used to create objects of a fixed cross-sectional profile. Aluminum is pushed through a die of the desired cross-section under high pressure, which makes it perfect for the creation of complex extrusions.Aluminum profiles are extremely versatile and can be used in a variety of applications. They are commonly used in the construction industry for window frames, door frames, curtain walling, and roofing. They are also used in the manufacturing of vehicles, aircraft, and other types of machinery due to their strength, light weight, and resistance to corrosion.Another advantage of aluminum profiles is that they are highly recyclable. This makes them an environmentally friendly choice for many industries. Furthermore, the extrusion process allows for the creation of complex shapes that would be difficult to achieve with other materials.In addition, aluminum profiles can be treated with a variety of finishes, such as anodizing, powder coating, and painting, to enhance their appearance and durability. This makes them a popular choice for both functional and decorative applications.The most common grade for aluminum profile is 6000 series,especiall is 6063-t5 and 6061-t6 aluminum profile.
