ü FSW & Extrusion 

Suitable for using extrusion technology to directly shape the cold plate flow channel, and opening the cycle through machining. The liquid cooling plate components are assembled using friction welding technology for welding and sealing. The surface of this type of liquid cooling plate is not suitable for too many screw holes.

ü FSW C&  Die casting

Die casting followed by friction stir welding: The water chamber is formed using die casting technology, which controls issues such as impurities and pores in the process. Further use friction welding for connection, which needs to improve reliability to avoid water leakage issues.
