Comparison of Die Casting, Cold Forging and Extrusion Forming Processes for LED Lamps_ Electronics/Circuits_ Engineering science and technology_ Professional data. For aluminum car, the aluminum profile drawing die needs to be opened. Die casting radiator needs to open die casting die Cold forging radiator needs to open forging die The LED lamp radiator is a heat dissipation structure composed of the matrix of the radiator and a number of heat sinks. The heat dissipation effect of the LED radiator mainly depends on the design of the heat sink lining plate and the heat sink in contact with the heating object. A well-designed LED radiator can achieve fast heat absorption, small thermal resistance and fast heat removal. The surface anodizing treatment also makes the wear resistance and corrosion resistance of the product greatly improved, and it can improve the service life of the product, improve the radiation capacity, and stabilize the heat dissipation effect.
