The development of presses will be further refined

According to relevant data, by 2015, China's total output of plastic products will reach 50 million tons. The good development prospect of the plastics processing industry is becoming the driving force for the rapid development of China's plastics machinery manufacturing industry, especially for some high-tech, high-performance, relatively modest-priced models, such as ultra-large, precision, energy-saving, environmental protection, and special injection molding machines. , Low-temperature, high-power single-screw extruders, multi-layer co-extrusion blow molding machines for producing high-impermeability and heat-resistant packaging materials, blow molding machines for industrial parts (auto parts, etc.), etc. All have very good prospects for development.
With the advancement of foreign technology and market development, China's press industry must accurately grasp the operating laws and characteristics of the market economy, develop unique technologies and equipment to meet the needs of specific markets, and use high-quality, high-efficiency equipment to meet the needs of users. At present, low-value-added general-purpose products have experienced structural oversupply, and low-level price vicious competition is hindering technological progress in the entire industry. Therefore, China's presses must renew their ideas, accelerate the transformation of economic growth, and promote technological innovation. The major models will also show different development characteristics in the future.
Injection Molding Machines In recent years, due to the rapid development of injection molding machines, in addition to mainframes, the general specifications of injection molding machines have exceeded supply, and it is difficult to maintain the sales volume at 1/3 of the peak period. However, for some high-tech injection molding machines, their market demand has gradually increased. The main performances are as follows: Firstly, the demand for full-electric and full-hydraulic precision injection molding machines has increased. The flagship markets for such products are electronic communications, audiovisual products, home appliances, and automobiles. These industries have high requirements for processing conditions, and therefore they are used in injection molding machines. The precision requirements have also improved. As the above industries are all in the Chaoyang industry and have a lot of room for development, the demand for such injection molding machines is also rising. The second is the rapid development of hollow injection molding machines. Due to the stress destruction of plastic parts under vibration, it has always been a major problem for automotive full plasticization and other engineering applications. The combination of various rubber and plastic materials, coupled with the hollow Injection molding technology can effectively improve this defect. This market demand has promoted the rapid development of hollow injection molding machines. Third, the new type of Injection molding machine is attractive, and new type injection molding machines with air-assisted and water-assisted devices will have a large market in the near future, especially in home appliances, automobiles, construction and other industries, because their products have more appearance requirements. High, and with a great deal of service life, these new injection molding machines are more attractive.
Extrusion machines have a breakthrough in technology and the application market continues to expand. Overall, the extruder market can maintain a slight upward momentum. However, the sharp drop in the domestic market price for extruders has been difficult to avoid. If phenomena such as shoddy and price wars occur, the overall image and market competitiveness of domestic presses will be seriously affected, and the development of the plastics processing industry will also be hindered.
In the past two years, only one company, KraussMaffei Germany, has dealt with more than 100 profiles production lines in China. In the plastic door and window and pipe processing industry, most of the powerful companies are seeking imported equipment. This cannot but be said to be the regret of domestic enterprises. In the future, the extruder mainframe and production line market will develop in the direction of increasing technological content and reducing prices. At present, domestically-made mainframes are mainly cone-type twin-screw and single-screw extruders, and their technologies are relatively mature, with the largest market sales volume. However, the general specifications of such products have exceeded supply, and can only maintain 50% to 60% of the peak period of the market. The main focus of the host product is to develop parallel counter-rotating twin-screw extruders, and to develop in the direction of the sixth generation, seventh generation, high speed, and large aspect ratio. The development direction of single screw extruder is large diameter, large ratio of length to diameter, and smooth exhaust. In fact, a single-screw extruder is a low-energy, low-cost model, and as long as the technology is right, it can basically achieve the performance of twin-screw extrusion. For example, the plastic extruders currently used in the United States are mostly single-screw and have replaced twin-screw extruders because of their high technological content.
Blow molding machine has a lower price (about 1/3 to 1/2 of the injection molding machine) and low energy consumption due to the blow molding machine (in injection molding, the pressure in the mold cavity is 15 MPa to 140 MPa, and the blow molding time The inflation pressure is generally lower than 1 MPa), strong adaptability, etc., to make up for the lack of injection molding processing methods, so that the formed industrial parts have a high degree of integrity, and the overall performance is good, the added value is high, and the cost is low. Although the blow molding machine currently accounts for the lowest percentage among the three major presses, it will maintain a strong momentum of development in the future and is the most promising model.
Auxiliary equipment such as auxiliary mixers, crushers, feeders, and heaters is an important part of the plastic production line, directly affecting product quality and production efficiency. At present, domestic manufacturers of such auxiliary engines are overwhelming, but their specifications are basically in the same range, and it is technically difficult to compete with imported machines. In addition, most of the imported plastic production lines have been equipped with the aforementioned auxiliary machinery, which in turn reduces the sales volume. As a result, the domestic auxiliary machinery market is highly competitive and the market capacity does not match the number of enterprises. The future development of this type of product is focused on: models with ultra-fine crushing, vacuum filtration, low noise, and high-speed crushing.
