　　Two major factors affecting the lifespan of die-casting molds

　　The factors involved in making the casting mold itself include:

　　Frequent mold repair and modification, major changes to the mold require the addition of wire cutting, welding, etc. After welding, the mold has a serious impact on production; Material factors, good imported mold steel has significant advantages in mold life, mainly reflected in the hardness of mold steel, which will not easily deform; Heat treatment processing and tempering are the key factors determining the strength and toughness of the mold, as well as eliminating residual stress.

　　Two die-casting operation methods and factors:

　　After the mold is installed on the machine, we should first preheat the mold to make its temperature almost the same as the temperature of the machine material; Whether it is machine sampling or mass production, molds need to be shipped with water, and the purpose of water transportation is to reduce the temperature of the molds.
