Injection molding is one of the important ways of material forming. Compared with mechanical processing, it has less processing technology, high material utilization rate, low energy consumption, easy production and high efficiency. Therefore, in the automotive, energy, machinery, electronics, information, aerospace and other industries, the production of necessities of life has been widely used. According to statistics, 75% of the roughly processed parts, 50% of industrial products, 80% of household appliances and electromechanical industries also need to account for more than 70% after processing. Mould industry is often able to drive the development of its related industries, so the mold industry is often called benefit amplifier. The development trend of mold and plastic products industry. Step by step with the transformation and upgrading of the industrial structure, low proportion of high-grade products, and gradually increase and continuous improvement, the basic formation of a complete set of service functions, plastic production growth has slowed down, but its value is still a large space, production can maintain rapid growth, we can see that the plastic processing industry is still in the ascending stage. As a measure of a country's development in the plastic industry, China's science and technology ratio is only "0, less than the world average 50:50, far more than Germany, 63:37, 70 and other developed countries: 30". Therefore, with the progress of technology and the upgrading of consumption, China's plastics industry will continue to develop steadily. Mold industry belongs to the basic industry of national economy, including machinery, automobile, light industry, electronics, chemical industry, metallurgy, building materials and other industries. The rapid development of China's industry, including automobile manufacturing, IT manufacturing and medical equipment development, has brought development opportunities to the entire mold industry. At present, China is in the period of industrial restructuring. The goal of planning emerging industrial countries is: by 2020, the added value of strategic emerging industries will account for about 15% of GDP. In order to achieve the target of 15%, in seven strategic emerging industries, high-end equipment manufacturing industry as the future pillar industry will be the development of national economy, as the mother of modern industrial mold industry, will benefit from the development of high-end equipment manufacturing industry.
