What is Car fog lamp frame ?

● Material and function of fog lamp frame

The plastic shell next to the fog lamp is often called the "fog lamp frame", which is a shell used to protect the fog lamp. The material of fog lamp frame is generally ABS plastic, which has the characteristics of wear resistance, impact resistance, high temperature resistance, etc. which can effectively protect the fog lamp frame and extend the service life of the fog lamp frame.

Its main function is to protect the fog lights from collisions or other damage, while also beautifying the appearance of the vehicle.

●Process flow and process principle of fog lamp frame

The fog lamp frame injection molding process mainly includes four stages: filling, pressure packing, cooling and demolding. The principle of injection molding process refers to the process of manufacturing semi-finished products with a certain shape through pressurization, injection, cooling, separation and other operations.

①Injection molding process: The injection molding process is from the beginning of injection molding to the clamping of the mold until the mold cavity is filled to about 95%. The function of the holding stage is to continuously apply pressure to compress the melt and increase the density of the plastic to compensate for the shrinkage behavior of the plastic. Driven by pressure, the plastic melt enters the vertical runner, main stream and diverter channels of the mold through the nozzle of the injection molding machine, and then enters the mold cavity through the gate, which is the process.

② Injection molding process principle: The injection molding machine uses the thrust of the screw (or plunger) to heat the raw materials, so that the plastic melts in the flow state and injects into the closed mold core. Under the drive of the screw or plunger of the injection machine, the injection system of the nozzle and the mold enters the mold cavity, and the product is obtained after drying and setting.
