How Injection Molding Is Used in Automotive Manufacturing

The plastic injection molding process is very important in the automotive industry because consistency, safety, and quality are important parts of accident prevention. Molten plastic is injected into existing molds for signal lights, interior lights, and other automotive lights and lenses, then cooled and hardened. After the plastic solidifies, the manufacturer removes the product and checks its quality before shipping it to the customer.

The challenge of the plastic injection molding process in automotive and other industries is to create reliable, well-designed molds. Poorly designed molds can cause defects and create errors during assembly. Before manufacturing begins, each mold is checked for integrity and quality to prevent this from happening.

Materials

Polycarbonate (PC) is used in automotive headlights because it has an 80% to 90% light transmittance. In addition, PC maintains its properties over a wide temperature range. Acrylic (PMMA) is also used in automotive lighting because of its optical clarity, strength, and resistance to ultraviolet (UV) light.

Surface Finish

Plastic covers for interior lighting fixtures require a high-gloss finish. At the end of the moldmaking process, the moldmaker applies the appropriate injection molding surface finish to the mold. This finish is then transferred from the mold to the surface of the molded part during the molding process. High-gloss finish standards used in the automotive industry, as defined by two associations, the Society of the Plastics Industry (SPI) and the Association of German Engineers (VDI), are required. Especially in North America, high-gloss finishes that meet SPI standards A-1, A-2, and A-3 are required.

Advantages of Injection Molding in the Automotive Lighting Industry

  • Precision and Repeatability: High precision and repeatability are crucial in automotive manufacturing, which is the core reason why the automotive industry favors injection molding.
  • Complex Shape Design: Injection molding produces complex parts through a process called “screw injection”, which helps to manufacture delicate and complex parts.
  • Fast and Efficient Manufacturing: The fast production process ensures that automotive manufacturers can meet their component needs efficiently.
  • High Surface Finish Quality: Parts produced through injection molding have excellent surface finish quality, providing a smooth and flawless surface.
  • Color Variety: Injection molding allows the production of parts with a variety of textures and colors without the need for post-molding coloring processes.

Automotive lighting injection molding application

Both interior and exterior automotive lighting applications are best accomplished using lenses, covers, and housings made through the plastic injection molding manufacturing process, with each molded plastic lens being made from a resin to meet color and optical specifications, typically including clear, red, amber, or yellow. Of course, many of these lighting applications are now using LED lamps. LED lenses do not need to meet the more stringent plastic lens requirements, and more traditional MAPs can generate a lot of heat, but the industry is constantly pushing the boundaries of lens performance. Temperature and clarity are always factors that must be carefully considered when developing automotive lighting product specifications and selecting the appropriate plastic resin. Common resin choices for automotive lighting include polycarbonate and acrylic, but each resin comes in a variety of formulations depending on the product requirements. The molds used to make clear automotive lighting parts are highly polished and require special care to keep them in optimal condition.
