Die cast machines have two general types:
1- Cold chamber machines: In this type, the injection cylinder is outside the melt, and metals such as AL, Cu, and Mg are injected, and the molten material is transferred into the injection cylinder by hand.
2- Hot chamber machines: In this type, the injection cylinder is inside the melt and the furnace, and metals such as dry lead and zinc are injected and the melt is injected automatically.
