Injection molding machine with a complex shape, size or precision with metal inserts with dense texture of plastic products, is widely used in national defense, mechanical and electrical, automotive, transportation, building materials, packaging, agriculture, culture and education and people Every area of everyday life. China's plastic processing enterprises Starbucks cloth, all over the country, the technical level of equipment is uneven, most processing equipment needs technical transformation. In recent years, the technological progress of our plastic machinery industry is very remarkable. Especially the gap between the technical level of injection molding machines and the famous brand products in foreign countries has been greatly reduced. Significant improvements have been made in terms of control level, product internal quality and appearance. Select domestic equipment, with a smaller investment, but also can produce the same quality of imported equipment and products. These create conditions for the technological transformation of enterprises.
The development of injection molding machine in China
At present, there are more manufacturers of injection molding machines in China. According to incomplete statistics, it has exceeded 60. Injection molding machine structure is vertical and horizontal two. By the production of products can be divided into ordinary and precision injection molding machine. An injection of 45-51000g; clamping force 200-36000kN; processing of raw materials are thermosetting plastic, thermoplastic and rubber three. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone and (acrylonitrile / butadiene / styrene) copolymers (ABS) and the like. From the processed products point of view, there are monochrome, two-color general and precision plastic products. The major manufacturers of these products have their own series, each with its own characteristics. Such as Guangdong Chun Tak Plastic Machinery Factory Co., Ltd. produced Czech Pa Pa CJ series of injection molding machines are available in both CNC and computer control of two forms. Another example is the Zhejiang Haitian Machinery Co., Ltd. Ningbo production HTF80X-HFT3600X series of injection molding machine can be used to produce a variety of high-precision thermal plastic products, the machine uses linear motion sensor control injection, clamping, ejection, the use of multiple CPU Electronic control system, large format color LED display, full automatic computer control.
Ordinary horizontal injection molding machine is still the dominant direction of the development of injection molding machine, the basic structure of almost no major changes, in addition to continue to improve its level of control and automation, reduce energy consumption, the manufacturer under the market changes are in the direction of portfolio series , As the same model injection molding machine configuration large, medium and small injection devices, combined into a standard and combined type, an increase of flexibility, expanded the scope of use and improve economic efficiency. ? In recent years, injection molding machine manufacturers in industrially developed countries in the world are continuously improving the functions, quality, supporting capabilities of auxiliary equipment, and automation level of ordinary injection molding machines. At the same time vigorously develop and develop large-scale injection molding machines, special injection molding machines, reaction injection molding machines and precision injection molding machines to meet the production of plastic alloy, magnetic plastic, plastic products with inserts needs. Injection molding machine is currently China's plastics machinery in the fastest-growing, the level of industrial development and the gap between the smaller one of the presses. But mainly refers to the ordinary type injection molding machine, in the extra large, all kinds of special, special, precision injection molding machine most varieties, some products are still blank, which is the main gap with the developed countries.
