The five key development direction of machine industry

According to the actual needs of the development trend of China's plastic products and productstructure adjustment and China's machine industry, the proposal in the next period of timefocused on solving the following five aspects of the technology.

A polymer material, composite, tensile, tensile, composite foaming technology equipment --foaming is extremely, forming an important special technology, relates to the formulation of raw materials, molding technology, plastic machinery and plastic mould. In recent years, China hasmade great progress in some areas, such as the PUR reaction injection, close to the Germanlevel; foam pipe, foam plastic net, foam films have reached the practical level. According to the development of foreign market demand, should focus on the biaxially oriented film forming technology and equipment, so as to achieve the practicality, the degree of commercialization ofequipment.

Two, flat extrusion molding process and equipment -- with "T" type (or hanger type) as a symbol of the die forming technology, in recent years the rapid development of overseas, and become more and more mature and perfect, and its importance for processing plastic components in the rapid rise. Our country is in the starting stage of development of this kind of technology and equipment, most of the blank. In recent years, China's PVC foamed sheet is part of the development of research and production units (Luca plug method and free foaming method)production line, poor technology, there is a big gap compared with foreign equipment. In order to master this technology, the key to solve the head, cooling, pressure equipment manufacturing,including the research object of rheological temperature taste. Based on the development of single-layer sheet production technology and equipment development, CO extrusion sheetproduction technology and equipment.

Three, the principle and application of electromagnetic dynamic -- electromagnetic dynamic extruder for the world's first, inherent in a certain range of some products have been successfully applied (such as for small and medium-sized blown film production). The extruder ismaterial saving, economic and social benefits of other technology can match. But it is not used widely, in addition to the need to address the corresponding forming device, the electromagneticdynamic extrusion theory remains to be solved under the heat balance of high speed and high efficiency, improve the plasticizing capacity and quality of high molecular weight material etc..

Four, on-line detection and automatic control technology -- in the plastics industry in developed countries, the number of injection molding materials, intelligent control and proportional servo system or technology has matured, and is rapidly updated to mention; extrusion molding equipment to achieve full online control, and establish a feedback system with online detection device. Domestic plastic molding equipment basically is a single control, line control, taking into account the large investment, high cost, thickness measurement device and the corresponding control technology rarely used.

Five, the foreign establishment and application of computer CAD/CAPP/CAM system has been widely applied in China, also have the basic conditions, should actively promote thepopularization and application of.
