What are the characteristics of the casting solidification produced by the casting machine?
The characteristics of heat exchange during solidification of castings by die casting machine: Once the molten metal enters the cavity, heat is transferred to the metal wall. The liquid metal dissipates heat through the wall, solidifies and shrinks, and the wall expands while obtaining heat and raising the temperature, resulting in a "gap" between the casting and the wall. Before the "casting-gap-metal" system does not reach the same temperature, the casting can be considered to be cooled in the "gap" and the metal-shaped wall is heated by the "gap".
The metal type hinders the effect of shrinkage on the casting: the metal or metal core has no retractability during the solidification of the casting and hinders the shrinkage of the casting, which is another feature of it.
