At present, the injection molding machine work rapidly, injection molding machine supplier also exist many questions, should follow the principle of foster strengths and circumvent weaknesses, when a create conditions to make their products to enter the world market, especially the advantage products should strengthen the efforts to export, the forward market share.

Injection molding machine is our country's production and use of the largest plastic machine variety. The first injection molding machine in China in the late 1950 s, the output, but because of time equipment technology content is low, can only use common plastic to produce technology request lower daily provisions, such as plastic box, plastic bucket, plastic containers, etc. After the rapid development of injection molding technology in China, new technology and new equipment emerge. The computer USES the high degree, the automation, the single machine multi-functionalization, the auxiliary equipment diversification, the combination agile and the equipment maintenance convenience becomes the trend. 

With the rapid development of the injection molding department in our country, the application and development of the relevant base production technology will definitely become the focus of the industry companies. It is very important to understand the research and development trend, process equipment, technology application and trend of domestic and foreign injection production base technology. 

In 2006, in injection molding, injection mold proportion to rise further, warm current mould and auxiliary mould level further forward, injection mold in terms of quantity and quality have rapid development, China's largest injection mold has a single set of weight exceeds 50 tons, the finest precision injection mold has reached to 2 microns. With the wide application of CAD/CAM technology, CAE technology has been widely used. 

In the current production, the injection pressure of almost all needles is based on the pressure of the plunger or the top of the screw on the plastic. The effect of injection pressure in injection molding is to defeat the movement resistance of the plastic from the feeding tube to the cavity, and the speed of the mold filling and the final compaction of the melting material. 

We should seize the opportunity, meet the challenge, and make the best of it and find out the space of our company. First, should establish export-oriented strategy, vigorously expand exports, encouraging the research institute, more companies to overseas office, especially in southeast Asia, the Middle East, Africa, Russia and eastern Europe market has great potential.
