< p > energy saving and safety < a href= "http://cailiao.sjfzxm.com/" > injection molding machine < /a > products will play an important and positive role in promoting the pformation and upgrading of China's plastics machinery industry and building a new industrial structure.

In recent years, China's plastics machinery industry has grasped the opportunities for energy saving and environmental protection products to become a hot spot in the market. A large number of high-efficiency and energy-saving plastic products have been launched, covering not only the various fields of the plastic products processing industry, but also the different demands of various manufacturers on the production of bulk plastic products and the production of precision products, and adapted to the higher requirements of the various sectors of the national economy, such as aerospace, defense, petrochemical, marine, electronics, optical and electrical communications, building materials, packaging, electrical appliances, automobiles and pportation, agriculture and light industries, and so on, and are favored by the market.

< p > the energy saving of the plastic machine can be divided into two parts: one is the power part, the other is the heating part.

Throughout the energy saving pformation of all kinds of injection molding machines in the market, servo energy saving pformation is the most reliable and feasible way of energy saving because of its high stability and high energy saving rate. Asynchronous servo energy saving is not only characterized by high power saving rate and high stability, but also low cost, low after-sales service and so on.

< p > traditional plastic machinery has certain potential in energy saving, because the previous design often focuses on the production capacity of single machine.

In the design of energy saving plastic machinery, production speed is not the most important index. The most important index is the energy consumption of processing unit weight products.

Therefore, it is necessary to optimize the mechanical structure, control mode and operation conditions of the equipment based on the minimum energy consumption.

< p > asynchronous servo energy saving series injection molding machine, equipped with high-performance servo variable speed power control system, in the injection molding machine molding process, to different pressure flow, make different frequency output, and carry on the accurate closed-loop control to the flow, realize the asynchronous motor's high speed response to the energy demand of the injection molding machine, and the best match and automatic adjustment.

Moreover, the energy saving rate of the servo pformation is determined according to the detailed parameters of the tonnage of the injection molding machine, the power of the motor and the time of cooling and keeping pressure. Generally speaking, the larger the tonnage is, the longer the cooling and holding time is, the higher the energy saving rate after the pformation, the more electricity saved, and the more electricity saved.

< p > traditional injection molding machines are supplied by quantitative pumps. The speed and pressure requirements of each injection process are different. It is through the proportional valve of the injection molding machine that the excess oil is returned to the oil tank through the oil return pipeline by overflow regulation. In the whole process, the speed of the motor is constant, so the oil supply is also fixed, and because the execution action is intermittent, and it can not be full load, there is a great waste of space for quantitative oil supply. According to the actual measurement, at least about 35-50%.

< p > < strong > China's injection molding machine and foreign storage gap < /strong > < /p >

< p > China's injection molding machine enterprises are mainly distributed in the southeast coastal area and the Pearl River Delta region. Among them, the Ningbo region has the strongest momentum of development. Now it has become the largest production base for injection molding machines in China. The annual production accounts for more than 1/2 of the total annual output of the injection molding machine in China, accounting for 1/3 of the world's injection molding machine.

Although China's injection molding machine industry develops rapidly and produces more varieties, it basically provides the general technical equipment needed for plastic raw material processing and plastic products processing and molding, and some products are also in the forefront of the world. However, compared with industrial developed countries such as Germany, Japan and Italy, there is still a certain gap between China's injection molding machine and its main products, such as few varieties, high energy consumption, low control level, and unstable performance.

< /p >

< p > at present, China's injection molding machine products are mainly concentrated in the general small and medium-sized equipment, with low technical content. In the 80-90 decade of twentieth Century, the supply of low-grade products exceeded demand, mechanical manufacturing capacity was surplus, and the efficiency of enterprises decreased.

Some varieties, especially the super fine and high-end products, are still blank and still need to be imported.

According to statistics in 2001, China imported foreign plastic injection machines for foreign exchange of 1 billion 120 million US dollars, while export injection machines made only 130 million US dollars in foreign exchange, and imports far exceeded exports.

< /p >

After China's entry into the world economic and Trade Organization (WTO), the foreign machinery manufacturing industry has accelerated the pfer of China's machinery manufacturing industry. Some famous enterprises in the world, such as Demark Demark, Krupp, Baden Phil, Japanese Sumitomo heavy industry and other companies in the world, have been "stationed" in China, and some have set up a technical center in one step.

The entry of foreign injection molding machinery manufacturers has brought vitality to China's injection molding machine industry, and has also made Chinese injection molding machine manufacturers full of opportunities and challenges.

< /p >

< p > in the coming period, our country must implement the overall plan of the comprehensive work plan for energy saving and emission reduction in 12th Five-Year, and push forward the work of industrial energy conservation and emission reduction.

Plastic machinery enterprises should actively carry out specialized production, change the disadvantages of being large and full, lack of high, fine and sharp points, improve the quality level of key parts, take the high efficiency and energy conservation as the development objective of the industry, and create the world famous brand products as the goal of struggle.
