Injection molding machine use and status quo

Updated: 2016-10-29

It is widely used in the fields of national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture, culture, education, health and people's daily life. It has the ability to shape complex shape, precise size or dense plastic products with metal inserts. Life in all areas. In the plastic industry, the rapid development today, regardless of the number of injection molding machines or varieties are occupies an important position, its total production accounted for the entire plastic molding equipment 20% - 30%, thus becoming the fastest growing plastic machinery, the number of production One of the largest models. According to statistics, from 1996 to 1998, China exported 8383 injection molding machines (sets), imported injection molding machine 42959 sets (sets), which in 1998 China's injection molding machine production reached 20,000 units, its sales accounted for the total sales of the presses 42.9%.

At present, China's production of injection molding machine manufacturers more, according to incomplete statistics has more than 2,000. Injection molding machine in the form of vertical and horizontal two. According to the production of products can be divided into ordinary type and precision injection molding machine. A injection volume of 45-51000g; clamping force 200-60000kN; processing of raw materials are thermosetting plastics, thermoplastic and rubber three. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone and (acrylonitrile / butadiene / styrene) copolymer (ABS). From the processing of the products, monochrome, two-color general and precision plastic products. These products are the main manufacturers have their own series, each with its own characteristics. Such as Guangdong Zhende Plastic Machinery Factory Co., Ltd. production Jieba CJ series injection molding machine each have a CNC and computer control of two forms. Another example is the HTF80X-HFT3600X series injection molding machine produced by Zhejiang Haitian Machinery Co., Ltd., which can be used to produce all kinds of high precision thermo plastic products. The machine adopts linear movement sensor to control injection, mold clamping, Electronic control system, large-format color LED display, the entire computer automatic control.

Ordinary horizontal injection molding machine is still the leading direction of the development of injection molding machine, its basic structure is almost no major changes, in addition to continue to improve its control and automation level, reduce energy consumption, the manufacturer according to the market changes are combined serialization direction , Such as the same type of injection molding machine configuration of large, medium and small injection device, combined into a standard type and combination, an increase of flexibility, expand the scope of use and improve economic efficiency.

In recent years, the world's industrial countries, industrial injection molding machine manufacturers are constantly improving the general injection molding machine function, quality, supporting equipment, supporting capacity, and automation. At the same time to develop and develop large injection molding machine, injection molding machine, injection molding machine and precision injection molding machine, in order to meet the production of plastic alloy, magnetic plastic, plastic parts with inserts needs.

Injection molding machine is the fastest growing plastic machinery in China, the level of industrial development and the gap between the smaller presses one of the varieties. But mainly refers to the ordinary type of injection molding machine, in the large, all kinds of special, special, precision injection molding machine most varieties, some products are still blank, which is the main gap with the industrialized countries.
