Correct use and protection of precision die casting molds: minimize rapid cooling and heating of the mold, maximize
continuous production, and prohibit high-speed injection under cold mold conditions. During the process of precision die
casting, the die casting mold has been changing back and forth between 160 degrees and 350 degrees. The hot expansion and
cold contraction of the return mold rapidly cools and heats up, resulting in mold fatigue damage. Therefore, during the
production of precision die casting, it is necessary to continuously produce as much as possible, reduce the rapid cooling and
heating of the mold, and extend the life of the mold.
