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 »

Shrinkage rate of die casting refers to the relative change rate of die forming size and actual size of die casting at room temperatureThe shrinkage rate of die casting includes liquid volume shrinkage of metal liquid, solidification phase transformation shrinkage and solid volume shrinkageThe more Read More »

After the metal liquid fills the cavity, the time required under the action of pressurization and specific pressure until the internal gate is completely set is called holding time.The effect of holding time is to crystallize the solidifying liquid metal under pressure, thus obtaining a die casting Read More »

The casting hot spot refers to the isolated area where the metal liquid cools and solidifies at some local locations during solidification in the mold cavity.The formation of hot spots usually depends mainly on the casting structure and wall thickness distribution (internal causes), and the local he Read More »

The slow injection velocity collects the first stage injection velocity in the three-stage injection system. After the metal liquid is poured into the pressure chamber, the filling degree of the metal liquid in the chamber is generally controlled at 50%-80%, and the rest space is filled with air.
