The working principle of aluminum alloy die castings for new-energy vehicle die-cast parts

It requires a molding process that involves the integrated use of die casting machines and aluminum alloy components. The principle behind die casting technology is to inject molten metal at high speed into a precision metal mold cavity under high pressure, where the metal solidifies into a casting as it cools under pressure. Cold chamber and hot chamber die casting represent the two fundamental approaches in this technology. In cold chamber die casting, the molten metal is manually or automatically poured into the injection chamber, after which the plunger advances, forcing the molten metal into the mold cavity. In contrast, in hot chamber die casting, the injection chamber is positioned vertically above the mold cavity, allowing the molten metal to flow automatically through an inlet located on the chamber into the mold. A pressurized plunger then moves downward, pushing the molten metal through a gooseneck tube and into the mold cavity. Once the metal has solidified, the mold is opened.
