A series of government requirements and regulations for vehicle fuel economy and emissions will directly promote the lightweight application of plastics in the automotive industry. At the same time, in the automotive industry, the application of LFT composites (long glass fiber modified plastics) in automobiles (front-end components, bumper brackets, seat frames, interior parts brackets, battery carriers, etc.) is increasing. With the development of the lightweight trend of the automotive industry, the relationship between automobiles and plastics is becoming closer and closer, and correspondingly, the connection between automobiles and injection molding technology and injection molding equipment is also getting deeper and deeper. The two complement each other, and it is obvious that automobile sales stimulate the injection molding machine industry and drive the development of the injection molding machine market.
