It is understood that annealing to the workpiece heating, when heated to the appropriate temperature, depending on the choice of materials for casting cooled slowly, it has reached the metal close to balance within the organization. Normalizing the workpiece is heated to a suitable temperature in the air cooled mainly used to improve the material cutting function network casting molds can also be used for some needs are not high end with die-cast parts. After quenching is to build heat insulation, water, and other inorganic salt solution or the like by the quenching medium rapid cooling die-casting mold drawings, through this procedure, produced by the steel will harden, but also to make steel brittle. In order to reduce the brittleness of steel, quenched steel may be placed at 650 degrees Celsius higher than the normal temperature for a long time a certain temperature insulation, then cooled die-casting mold, which is called tempering. Die Casting is a pressure cast parts casting molds, and is a cast using installed pressure die casting mold casting machinery die-casting machine, the heating of copper, zinc, aluminum or aluminum alloy liquid metal is poured into the die casting machine spout, die-casting mold industry, Chang Technologies, Fugong casting molds provided by Chang Tong Technology Co., Chang Tong Technology Co., Ltd.
