Injection molding is a method of manufacturing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding and die-casting. Injection molding machine (hereinafter referred to as injection molding machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is realized through injection molding machines and molds.

According to the definition and classification of the injection molding industry, injection molding is divided into three categories: rubber injection molding, plastic injection molding and molding injection molding: 1. Rubber injection molding: rubber injection molding is a production method that directly injects rubber from the machine barrel into the mold for curing. The advantages of rubber injection molding are: although it is intermittent operation, the molding cycle is short, the production efficiency is high, the embryo preparation process is canceled, the labor intensity is small, and the product quality is excellent.

The definition and classification of the injection molding industry shows that 2. Plastic injection molding: plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, and the desired plastic parts are obtained by cooling molding. There are mechanical injection molding machines specially used for injection molding. At present, the most commonly used plastic is polystyrene.

The definition and classification of the injection molding industry shows that 3. Injection molding: the resulting shape is often the final product, and no other processing is required before installation or use as the final product. Many details, such as bulges, ribs and threads, can be formed in one step of injection molding.

In recent years, with China's continuous technological breakthroughs in the injection molding machine industry, China's import and export trade of injection molding machines has been in a trade surplus. In terms of export, according to the relevant statistical data of the definition and classification of the injection molding industry, the export scale of China's injection molding machines has shown a fluctuating upward trend since 2015. In 2021, the export volume of China's injection molding machines was 49294, a year-on-year decrease of 31.6%; The export volume was US $1.693 billion, up 39.6% year on year.

From the perspective of the export price trend of injection molding machine products, since 2015, the export price of China's injection molding machine products has shown a fluctuating downward trend. In 2018, the average export price of China's injection molding machine products was 16000 US dollars per unit, the lowest in recent years, and then the price rebounded. By 2021, the average export price of China's injection molding machine products was 34400 US dollars per unit, a significant increase over the same period last year.

Injection molding is mainly used in the industrial field, which is the method of industrial product production molding. With the development of the injection molding market, China's injection molding machine industry technology is also constantly improving.
