    What is Die Retention Time And What Effects Does It Have?
    Mold retention time: the time from the end of the hold-down stage to the release of the die casting. The purpose of this time is to ensure that the casting is fully solidified, cooled and has a certain strength in the die, so that the die casting will not be deformed or cracked during the release an Read More »

    The Role of Heating and Cooling Systems
    Before the die casting production, the mold should be fully preheated and kept within a certain temperature range during the die casting process. Its main functions are as follows:The die can achieve better heat balance and improve the solidification condition of casting sequence so that the solidif Read More »
