Abstract

According to the development trend of China's plastic products and the needs of product structure adjustment, as well as the actual situation of China's plastic machine industry, the relevant parties suggest that the following five aspects of technology should be solved in the next period of time. 1. polymer material stretching, compounding, foaming technology equipment-stretching, compounding, foaming is a very important special technology in molding, involving raw material formula, molding process, plastic machinery and plastic mold. In recent years, China has made great progress in some areas, such as PUR reaction injection, close to the German level, foam pipe, foam film has reached a practical level. According to the market demand of foreign development,

According to the development trend of China's plastic products and the needs of product structure adjustment, as well as the actual situation of China's plastic machine industry, the relevant parties suggest that the following five aspects of technology should be solved in the next period of time.

 

1. polymer material stretching, compounding, foaming technology equipment-stretching, compounding, foaming is a very important special technology in molding, involving raw material formula, molding process, plastic machinery and plastic mold. In recent years, China has made great progress in some areas, such as PUR reaction injection, close to the German level, foam pipe, foam film has reached a practical level. According to the market demand of foreign development, we should focus on the research of biaxially oriented film forming technology and equipment, so as to achieve the degree of practical technology and equipment commercialization.

2. flat extrusion molding technology and equipment ---- "T" type (or coat rack) head as the symbol of the molding technology, in recent years, the rapid development of foreign countries, and increasingly mature, perfect, its importance and in the plastic processing in the share of the rapid rise. China's such technology and equipment is in the initial stage of development, most of the equipment is blank. In recent years, some research and production units in China developed PVC foam board (plug card method and free foaming method) production line, poor process, compared with foreign equipment there is a big gap. In order to master this kind of technology, we should focus on the equipment manufacturing of the head, cooling and calendering devices, including the study of temperature and object rheology. In the development of single-layer sheet production technology equipment basic education, the development of co-extrusion sheet production technology and equipment.

3. electromagnetic dynamic principle and application-electromagnetic dynamic extruder for the world's first, a certain range of products have been successfully applied (such as for small and medium-sized blown film production). The extruder is energy-saving and material-saving, and its economic and social benefits are unmatched by other technologies. However, the current range of use is not wide, in addition to the need to solve the corresponding molding device, in the electromagnetic dynamic extrusion theory still needs to solve the heat balance under high speed and high efficiency, improve the plasticizing ability and quality of high molecular weight materials and other issues.

4. on-line detection and automatic control technology-in plastic industry developed countries, the digital, intelligent control and proportional or servo system technology of injection molding materials has matured and is rapidly updating and upgrading. Extrusion molding equipment realizes full-line on-line control and establishes a feedback system with on-line detection devices. Domestic plastic molding equipment is basically a stand-alone control, less line control, taking into account the large investment, high cost, thickness measurement device and the corresponding control technology is rarely used.

The establishment and application of 5. computer CAD/CAPP/CAM system-abroad has been widely used, the domestic also has the basic conditions, should actively promote the popularization and application.

How to Prevent Mold in Plastic Electroplated Parts

In the summer, some plastic electroplating plants in the south often find some white spots on the plated parts, and it is difficult to wipe off, affecting the appearance of the product, and even lead to scrap. Although the electroplating process conditions are normal, it is difficult to avoid, and even large quantities.
