[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Automotive injection molding refers to plastic parts produced using injection molding technology during the automobile manufacturing process. Injection molding is a common processing method that injects molten plastic material into a mold and obtains the desired shape of the parts after cooling and solidification. Automotive injection molding parts have high plasticity and durability and are widely used in automotive interior and exterior trims, engine accessories, seat brackets, fenders and other parts. After the injection molding of automotive parts is completed, the finished product needs to be ejected to facilitate the removal of the finished product.
