Plastic parts industry - industrial upgrading direction of plastic products

At present, China's plastic products industry is in the stage of industrial upgrading. Seeking new growth opportunities is the key to break the situation of traditional plastic products enterprises. According to the research data, the plastic parts industry has developed into an important sub-industry of the plastic products industry, and the plastic parts industry is one of the main directions of the technical upgrading of plastic products.

Plastic parts are the general name of parts and components with plastic as the main material. They are application-oriented and penetrate into different downstream application fields with rich product categories. They are important components of downstream end products in terms of appearance, function, structure, etc.

China's plastic parts industry started late due to the influence of mold development, processing capacity and other factors. On the one hand, most of the plastic parts are non-standard products, and mold processing is used as the molding method. However, the overall level of independent design and development capability of the plastic parts enterprises in China is relatively low, especially for high-end fields with high requirements for product precision and quality, the mold design and development capability is difficult to meet the needs of customers; On the other hand, plastic parts processing is a production process that combines material properties, processing technology, processing equipment, production environment and other factors, which requires higher production management ability and production experience of the production enterprise.

With the development of China's mold industry, the ability of mold design and development of plastic parts enterprises has been continuously strengthened, and some enterprises with technical strength have the ability of precision mold design and development; At the same time, with its own accumulation over the years, the production capacity of China's plastic parts industry has also been improved to a certain extent, the production efficiency and product quality have gradually improved, and "import substitution" has been realized in some high-end product markets. In 2018, enterprises above the designated size of China's plastic products industry achieved 1806.175 billion yuan of main business income and 950.4 billion yuan of total profits, of which plastic parts and other enterprises above the designated size of plastic products achieved 505.146 billion yuan of main business income and 26.318 billion yuan of total profits. The plastic parts industry has become an important industry in the plastic products industry.

Due to the strong application-oriented characteristics of plastic parts, the continuous expansion of new application fields will bring incremental market space for plastic parts. At present, under the trend of global energy conservation and environmental protection, plastic parts are gradually replacing traditional metal parts in downstream industries such as automobiles and household appliances with their "lightweight" characteristics; In addition, due to the low density of plastic parts, corrosion resistance to acid, alkali and organic solvents, good insulation, wear resistance, shock absorption and noise reduction and self-lubrication, plastic parts can be used in many places where metal and non-metallic materials are not competent, so the application and development potential of plastic parts is huge. With the development of polymer material technology and the improvement of plastic processing technology, the application and development of plastic parts in industry, agriculture, construction, transportation, national defense and military industry, aerospace and other fields will be further deepened.
