哈希私彩During mold processing, some ordinary equipment cannot be completed, such as some inner cavities with small R angle, and the electrode is electric pulse processing. These are used, generally made of red copper or graphite. With the rapid development of automatic machining die manufacturing technology in Dalian, it has become an important part of modern manufacturing technology. Modern mold manufacturing technology is developing towards accelerating information driven, improving manufacturing flexibility, agile manufacturing and systematic integration. It is embodied in the CAD / CAM technology of the die, the laser rapid prototyping technology of the die, the precision forming technology of the die, the ultra precision machining technology of the die, the dynamic simulation technology of the flow, cooling and heat transfer process by using the finite element method and boundary element method in the design of the die, and the CIMS technology of the die, It has developed advanced manufacturing technologies such as die DNM technology and NC technology.
