  Description of Precision Forging Contact
Application applied in megavolt ultra-high voltage grid (highest voltage level in the world) and exported to Toshiba (Japan)
Client Problem Toshiba sets high standard on the performance, dimension, accuracy and surface smoothness of the contact finger while manufacturers can hardly meet the standard QINHAN Solution with full understanding of the demands of Toshiba, QinHan realizes once forming by cold forging process
Benefits the hardness is HB80; the rate of finished products is up to 100% and the cost is reduced by more than 50%.
