| Message: | Copper can be die-cast, and the floor socket on the electrical appliance is copper die-cast. The mold material and heat treatment must be good, and the general life is okay. Do not use 3cr2w8v and do not nitride. Conventional hot work die steel can be, for example, H13, SKD61, DH-31S, 8407, W302. Due to the high temperature of the alloy liquid during the production of copper alloy die-casting, the thermal shock to the mold is greater, and the mold is more prone to thermal fatigue and cracks and cracks. Some heat shock-resistant materials are better now. url:http://www.mnwparts.com |
