Current situation of plastic industry: promising prospect and many problems
with the progress of processing technology and production equipment, thermoplastic / thermosetting plastic products with plastic materials as production raw materials and treated by different production and processing processes such as hollow molding are more and more widely used in different occasions of production and life. Plastic products are widely used in different industries such as light industrial machinery, agriculture and forestry transportation.
however, as plastic products are high molecular polymers, how to dispose of waste plastic products has become a difficult problem. With simple landfill treatment, plastic products are difficult to decompose and will pollute the soil environment. If incineration is carried out, the auxiliary materials added in the plastic production process will produce toxic and harmful gases and pollute the air environment.
it is understood that the emergence and development of recycled plastic industry is expected to solve the pollution problem of plastic products. In recent years, people have paid more and more attention to the quality of living environment, and the public's awareness of environmental protection has been continuously enhanced. In addition, the rising price of crude oil has pushed the price of plastic raw materials higher. The clean and environmentally friendly recycled plastic industry has obtained a good opportunity for development. According to industry experts, through the adjustment of products and industrial structure through technological innovation, China's recycled plastic industry has made great progress and is developing towards the direction of high quality, multiple varieties and high technology.
although China's recycled plastic industry has a promising prospect, it still faces many problems in the actual development process. On the one hand, because recycled plastics come from a wide range of sources, their quality is uneven, and the performance difference between batches is also great, which leads to the relatively low quality stability of recycled plastics; On the other hand, the cost of recycled plastic is relatively high, and its price is higher than that of original plastic. In addition, from the overall situation of the current recycled plastic industry, domestic waste plastic recycling enterprises are still mainly small and medium-sized enterprises, and the industry concentration is relatively scattered. As the recycling of waste plastics is a complex process, the technical requirements are relatively high. However, China's domestic recycled plastic industry is still dominated by physical recycling, which undoubtedly hinders the development process of the whole industry to some extent.
experts believe that under the background of vigorously promoting circular economy, carrying out traditional industrial reform and promoting environment-friendly sustainable development, although there are still various problems to be solved in the domestic recycled plastic industry, the development prospect of the recycled plastic industry is still bright. Domestic plastic industry enterprises should seize the opportunity to develop renewable plastic production projects and promote the green development of the industry.
some domestic plastic molds began to replace imported products
mold industry is a basic industry in the national economy, specifically involving machinery, automobile, light industry, electronics, chemical industry, metallurgy, building materials and other industries, with a wide range of applications. With the rapid development of China's industry, the development of automobile manufacturing, it manufacturing and medical devices has brought opportunities for the development of the entire mold industry.
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 successfully entered the supply chain system of some high-end industries, replacing some imported products and getting rid of their dependence. However, it is undeniable that only a few of them have entered the international high-end market.
with the improvement of the technical level of China's mold industry and the gradual increase of product levels, some international mainframe industry supply chain systems are further inclined to domestic enterprises, which will be an opportunity and challenge. It is understood that by 2015, the independent matching rate of molds required by the Chinese market will reach more than 85%, among which the independent matching rate of medium and high-end molds will be significantly increased.
some experts pointed out that in the future, China's mold industry should not only continue to improve its production capacity, but also focus on the internal structure adjustment and the improvement of the level of technological development. It mainly refers to the adjustment of enterprise structure towards specialization, the development of product structure towards medium and high-end molds, the improvement of import and export structure, the forming analysis and structural improvement of automobile panel molds, the application of multi-functional composite molds and composite processing and laser technology in mold design and manufacturing, high-speed cutting, ultra precision machining and polishing technology, and informatization.
