Cold forging + stirring welding radiator

        Due to the limitation of mold and equipment, high-power cold forging products can not be processed in one time. The traditional process cost is too high, and multiple modules need to be spliced, resulting in a relatively low thermal conductivity, and the structural strength is only 70% of the base metal. The stability and strength are Declined. The friction stir welding process can solve the above problems well.
