After the reform and opening up in China, due to the rapid development of industrial manufacturing, has been very big demand for all kinds of industrial equipment, injection molding machine which is one of them.
Injection molding machine and injection machine and injection machine. It is the thermoplastic or thermosetting material using plastic molding mold made into various shapes of plastic products mainly molding equipment. Divided into vertical, horizontal, full battery. Made of melted plastic injection function heating plastic, under pressure, injection and make it full of mold cavity.
It is one of the largest processing machinery, plastic processing industry in the usage not only have a large number of products available injection molding machine production directly, but also of note, blowing process of key equipment. Data show that domestic injection molding machine manufacturer, which has more than 2000, production is accounted for 60% of the world.
China has become the world's largest country in machines in PCS/sets of production, the reason: to promote the development of China's injection molding machine equipment manufacturing is a joint venture with international famous enterprises and technological cooperation; Second, Chinese enterprises gradually adapted to the mechanical parts adopt international purchase way, mastered the asc purchase channels. At the same time, the production of the injection molding machine of our country present a strong regional features, ningbo in zhejiang province and guangdong dongguan and other places, has become China's important production base of injection molding machine and the world.
It can have a molding complex shape, size precision, or with a metal insert of the texture is fine and close the ability of plastic products, widely used in national defense, electrical, automotive, transportation, building materials, packaging, agriculture, culture and education of health and People's Daily life. Today with the rapid development of plastic industry, injection molding machine both in quantity and variety on occupies an important position, the total number of production, accounting for 20% - 30% of the whole plastic molding equipment, thus become the fastest growing in the plastic machinery, one of the largest number of models in production.
Because of the rapid injection molding machine industry development in China, now in addition to the mainframe, injection molding machine has an oversupply of general specification, sales is difficult to maintain the 1/3 of the peak. However, for some of the high content of science and technology in injection molding machine, its market demand is gradually strengthened. All electric, hydraulic precise injection molding machine of the requirements. This kind of product's main market is electronic communications, audio-visual, household appliances, sunrise industries such as cars, these industries for processing conditions the demand is higher, so for the injection molding machine precision requirement is high also.
In addition, with saving energy and reducing consumption rises for national strategy, injection molding machine and energy saving problem has been widely concerned. At present, the conventional injection molding machine in the field of energy saving for motor with frequency converter and servo motor two more mature, the servo motor is more and more widely accepted.
Servo energy-saving series injection molding machine, equipped with high-performance servo dynamic variable speed control system, in the process of injection molding pressure on different traffic, make different frequency output, and closed loop control of pressure flow accurately, realize servo motor for injection molding machine high speed response and the best match of energy demand and adjust automatically.
This time, our country the first intelligent CNC junior officially offline 4500 tons of super large injection molding machine, will mark the injection molding machine in our country will enter the intelligent era, on the related technologies are gradually narrow the gap between mainstream level with the world.
