friction stir welding heatsink
About Friction Stir Welding
Due to customers' special requirements for heat sink, if you want a heatsink more than 300mm wide , we can use the friction stir welding technologyto weld two or three parts together to be your desired width. We have several advanced friction stir welding equipments with very mature welding experience, which has high welding fastness,no auxiliary welding,no air bubbles, can also meet the welding requirements in aerospace industries, The surface of the substrate is smooth, welding line is not seen on baseplate surface .hide in the fins,and the welding area can do any surface treatment, This technology is very advanced technology in the domestic heatsink market. Solved the problem of high cost and difficulty in extruding ultrawide heatsink.
