주입 형 are mainly used for the molding of thermoplastic products, and more and more of them are used for molding thermosetting plastics in recent years. Injection molding occupies a large proportion in the molding of plastic products, and thus about half of the production of plastic molding molds are injection molds.

However, with the intense competition in the home appliance market, housing design has become an important part of the new requirements for the color, feel, accuracy, and wall thickness of home appliances. Industry insiders generally believe that large-scale, precise, and well-designed (mainly thin-walled products) injection molds will be welcomed in the market in the future. It is understood that the household electrical appliance industry expects the annual growth rate of mold products for the household appliance industry during the “12th Five-Year Plan” period. About 10%, which will also greatly promote the development of the domestic mold industry.

In addition, for the domestic auto and motorcycle industry, China’s total automobile output has exceeded 3.25 million in 2012, an increase of approximately 38.49% over the previous year, and the growth rate is alarming. As a result, the potential market for automobile molds is huge. At present, China's large-scale precision mold manufacturing capacity is still insufficient, and the cover models for domestic mid- to high-end cars are almost all imported products. Therefore, the development of its own large-scale precision automobile cover molds with high technological content is an important task in the future.
