Injection molding of BMC plastics requires specialized equipment

When it comes to automotive plastics, Car Light Molding is an important part of the automotive manufacturing process. These parts are critical for the safety of a vehicle and must meet strict design requirements. The most common types of molds used for automotive lighting parts include the original body, the utility model, and the decorative model. These molding compounds are typically thermosetting, which means that they are heat resistant, flame retardant, and tough. Here are some advantages of using the Utility model to manufacture your next headlight:

Decorative Frame: The frame is part of the headlight assembly, and it can be seen through the lens from the outside of the car. Typical materials used to manufacture this type of mold are PC, PBT+GF, and PA + GF. To ensure that your molds are made from quality materials, they must undergo high-tech plating processes to create smooth surfaces without flow marks. Mold design and manufacturing are also important components in the process.

Transparent Taillight Cover: The exterior light covers of the MINI Superleggera Vision concept car are finished with a transparent PLEXIGLAS(r) taillight cover. Transparency in the taillight covers helps create a high-quality overall impression. Unlike LED taillights, which can cause hot spots, PLEXIGLAS taillights have a transparent surface. As a result, your vehicle's taillights will be a stunning feature of your vehicle.

Increasing the speed of plastic injection molding is a great advantage for automotive lighting manufacturing. Headlights are typically 30 millimeters thick and require a 20-minute cycle time. Multilayer injection processes have made this process possible, and promise to decrease the cycle time further. The benefits of reducing cycle time include faster production and lower manufacturing costs. Once the cycle time is reduced, the cost of manufacturing the Car Light will become more affordable.

Specialty Plastics: Injection molding of BMC plastics requires specialized equipment. A high-speed CNC machining machine and a special molding tool are needed. The temperature control system will greatly influence the molding cycle. Since the automotive headlight reflector is made of BMC material, the molds used for this process are very different from thermoplastic injection molding. For instance, the barrel portion of an injection molding machine will utilize a special freezer for cooling ice water, while the core will require electric heating.
