As a plastic injection molding manufacturer and supplier, specializing in thermoplastic injection molding technology. Our expertise also includes gas injection molding technology, high gloss and electronic molding. Our injection molded automotive exterior and interior parts for the automotive industry are mainly made of: - Polystyrene (PS), - Polypropylene (PP), - ABS, - PC, - PC / ABS, - PC / PMMA. Advantages of injection molding in automotive applications Injection molding is a well-established production process in which an automotive mold maker injects molten plastic material into a mold cavity. The molten plastic then cools and hardens, and the manufacturer removes the finished part. While the mold design process is critical and challenging (poorly designed molds can lead to defects), injection molding itself is a reliable method for producing solid plastic parts with a high-quality finish. Here are a few reasons why the process is beneficial for the production of automotive plastic parts: 1. Repeatability In the automotive industry, repeatability - or the ability to consistently produce the same part - is critical. Because automotive plastic injection molding typically relies on a robust metal mold, the final molded automotive part produced using that mold is virtually identical. Some factors can affect injection molding, but if the mold has good design and finishing, injection molding is a highly repeatable process. 2. Size and Cost The injection molding process can be an expensive process due to the cost of the mold. However, it is still a highly scalable process, and as manufacturers make more parts, their overall cost decreases. Therefore, for mass production applications, injection molding can be beneficial to the manufacturer. However, for any non-mass-produced product, injection molding tooling costs may limit the cost efficiency of the process. 3. Material Availability A significant advantage of using injection molding in automotive production is the wide variety of rigid, flexible and rubber plastics that the process is compatible with. Manufacturers use a variety of different polymers for various applications in the automotive industry, including ABS, polypropylene, acrylic, acetal, nylon, polycarbonate and more.
