[0002] Injection molding, also known as injection molding, is a method for producing industrial products, primarily plastics. During the process, raw materials are added to the barrel of the injection molding machine in pellet form. Heat and the screw melt the raw materials into a liquid state, which is then rapidly injected into a closed mold under pressure. After cooling and solidification, the mold is opened and removed, resulting in the desired plastic product, also known as an injection molded part.
