The definition and classification of injection molding industry mention that injection molding is divided into 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 barrel into the mold for vulcanization. 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 show that 2. Plastic injection molding: plastic injection molding is a method of plastic products. Molten plastic is injected into the plastic product mold by using pressure, and the desired plastic parts are obtained by cooling molding. There are mechanical injection molding machines specially used for injection molding. At present, polystyrene is the most commonly used plastic.
The definition and classification of injection molding industry show that 3. Injection molding: the shape obtained is often the final product, and no other processing is required before installation or use as the final product. Many details, such as bulge, rib and thread, can be formed in one step of injection molding.
In recent years, with China’s continuous technological breakthrough in the injection molding machine industry, China’s import and export trade of injection molding machines has been in a favorable situation. In terms of export, according to the definition and classification of the injection molding industry, the export scale of China’s injection molding machines has shown an upward trend since 2015. In 2021, the national export volume of injection molding machines will be 49294, down 31.6% year on year; 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 downward trend of shock. In 2018, the average export price of the national injection molding machine products was 16000 dollars/set, the lowest in recent years, and then the price rebounded. By 2021, the average export price of the national injection molding machine products was 34400 dollars/set, 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 modeling. With the development of the injection molding market, the technology of China’s injection molding machine industry is constantly improving.
