In recent years, the average annual growth rate of China's plastic industry has reached more than 10%, and the annual output of plastic products ranks second in the world. Plastic products have developed rapidly in agriculture, plastic packaging, plastic pipes and profiles, automobiles, household appliances, electronics, transportation and other fields, setting off an investment boom.

According to the analysis of Luo Baihui, Secretary General of the International Mold Association, China's plastic mold has formed a huge industrial chain driven by high technology and the application demand of pillar industries. From the upstream material industry and processing and testing equipment to the downstream machinery, automobile, motorcycle, household appliances, electronic communications, building materials and other major application industries, the development of plastic mold is in the ascendant.

Construction and building materials industry

The construction industry is the pillar industry of the national economy. In the next 5-10 years, China's construction industry will have greater development, become a new consumption hotspot and economic growth point in the Chinese market, and drive the development of chemical building materials industry. As the country has banned the use of cast iron pipes and replaced them with plastic pipes, it is expected that 80% of the indoor drainage pipes of new residential buildings and 50% of the urban water supply pipes will use plastic pipes this year. At the same time, the country is vigorously developing plastic doors and windows, and it is expected that the penetration rate of plastic doors and windows will reach 30% - 50%. Since the 1980s, plastic doors and windows and water supply and drainage pipe fittings in China have developed rapidly through technological digestion and development on the basis of imported equipment and technology. During the 12th Five Year Plan period, plastic pipes, plastic doors and windows, and new waterproof materials have become the development focus of the chemical building materials industry. Plastic building materials can not only replace steel, wood and traditional building materials, but also have the advantages of energy saving, material saving, ecological protection, improving living environment, improving building function and quality, reducing building self weight, convenient construction and so on, which will be more and more applied in the future.

The extrusion die of chemical building materials is the key process equipment for the production of new chemical building materials, mainly including plastic profile extrusion die, plastic pipe fitting die, low foaming molding extrusion die, etc. According to Luo Baihui, its technical performance directly affects the quality and output of new chemical building materials. At present, plastic profile extrusion dies are mainly used to produce plastic door and window profiles. The market share of plastic doors and windows in Germany is as high as 80%, and that in other Western European countries is also 30% - 40%. China is vigorously promoting plastic doors and windows.

Pipe fitting mold is an injection mold with great difficulty in processing, which is used to produce plastic water supply and drainage pipe fittings in urban buildings. It is expected that the demand for plastic building materials molds will grow rapidly, and various profile extrusion molds and plastic pipe fitting molds will become new economic growth points in the mold market.

Plastic mold industry chain needs to break through the bottleneck
