The IGBT heat sink is adopted the friction welding process, the two pieces of aluminum heat sink friction welding together, so as to achieve the IGBT heat sink need cross section, Finally, the integrated appearance structure and uniform heat dissipation performance are formed after CNC processing, the friction welding process can reduce the cost of the mould, cycle time is long, high stability. Lori has developed a variety of standard aluminum heat sink materials and continuously enhanced the standard materials database to provide customers with more joint solutions to choose from. The IGBT heat sink processing process is as follows
