Along with the advancement of processing technology and production equipment, thermoplastic/thermosetting plastic products processed by different molding processes such as hollow molding are widely used in the production and living of different places, light industrial machinery, agriculture and forestry. Plastic products are widely used in various industries such as transportation.

However, since plastic products are high molecular polymers, how to deal with waste plastic products has become a problem. Simple landfill treatment, plastic products are difficult to decompose, and will also pollute the soil environment. If incinerated, the added materials in the plastic production process will produce toxic and harmful gases, polluting the air environment. 

It is understood that the emergence and development of the recycled plastics industry is expected to solve the problem of pollution of plastic products. In recent years, people have paid more and more attention to the quality of the living environment, the people's awareness of environmental protection has been continuously enhanced, and the price of crude oil has risen, pushing the price of plastic raw materials higher. The clean and environmentally-friendly recycled plastics industry has got a good opportunity for development, industry personnel introduction, and products with technological innovation. With the adjustment of industrial structure, China's recycled plastics industry has made great progress and is developing towards high quality, multi-variety and high technology.

Although China's recycled plastics industry is promising, in the actual development process, it still faces many problems. On the one hand, due to the wide range of recycled plastics, the quality is uneven, and the performance difference between batches is also great, resulting in low quality stability of recycled plastics. On the other hand, the cost of recycled plastics is relatively high, and its price is high. The price of the original plastic.

In addition, from the overall situation of the current recycled plastics industry, domestic waste plastic recycling enterprises are still dominated by small and medium-sized enterprises, and the industry concentration is relatively scattered. Since recycling and recycling of used plastics is a complicated process, the requirements for technology are relatively high. The domestic recycled plastics industry is still dominated by physical recycling, which undoubtedly hinders the development of the entire industry to some extent.

With the improvement of the technical level of China's mold industry and the gradual increase of product levels, some international host industry supply chain systems are now tilting toward domestic enterprises, which will be an opportunity and challenge. It is understood that the independent matching rate of molds required by China's market will reach more than 85%, and the self-supporting ratio of medium and high-end molds will be significantly improved. 

It is pointed out that in addition to continuing to increase production capacity, China's mold industry should focus on internal structural adjustment and technological development. Mainly the enterprise structure to professional adjustment, product structure towards the development of high-end molds, improvement of import and export structure, mold forming analysis and structural improvement of high-end automotive cover parts, multi-functional composite mold and composite processing and laser technology in mold design and manufacture Application, high-speed cutting, super finishing and polishing technology, information technology development. 

It is believed that under the background of the country's vigorous promotion of circular economy, the promotion of traditional industrial reform, and the promotion of environmentally friendly and sustainable development, although the domestic recycled plastics industry still has various problems to be solved, the development prospect of the recycled plastics industry is still bright. Domestic plastics industry enterprises should seize the opportunity to develop recycled plastic production projects and promote green development of the industry. Some domestic plastic molds have begun to replace imported products. 

In recent years, domestic enterprises have continued to improve mold technology and products. Therefore, some plastic molds or injection molded parts have begun to circulate internationally, and have successfully become a supply chain system for some high-end industries. Some imported products have got rid of their dependence. But it is undeniable that only a few parts of the international high-end market. 

The mold industry belongs to the basic industry in the national economy, specifically related to machinery, automobile, light industry, electronics, chemical, metallurgy, building materials and other industries, and its application range is very wide. China's industrial development is rapid, and the development of automobile manufacturing, IT manufacturing and medical equipment has brought the entire mold industry to the opportunity of development.
