The cold forging process is to forge the product at room temperature. The product has high shape and dimensional accuracy, good internal density, high strength of the workpiece, smooth surface, few processing procedures, and is convenient for mass production.

Cold forged heat sinks are widely used for heat dissipation of LED lamps. The shapes of cold forged heat sink include plate pin fin heat sinks, round pin heatsinks and oval fin heat sinks. Using cold forging heatsink will reduce the overall weight and volume of LED lamps to achieve The purpose of reducing the overall cost is to make the product more competitive!
