Aluminum Die Casting 03

详情

Hot chamber machines are used primarily for zinc copper, magnesium, lead and other low melting point alloys that do not readily attack and erode metal pots, cyliners and ***** injection mechanism of a hot chamber machine is immersed in the molten metal bath of a metal holding furnace .The furnace is attached to the machine by a metal feed system called a gooseneck.As the injection cylinder plunger rises, a port in the injection cylinder opens, allowing molten metal to fill the cylinder.As the plunger moves downward it seals the port and forces molten metal through the gooseneck and nozzle into the die cavity After the metal has solidified in the die cavity , the plunger is withdrawin, the die opens and the casting is ejected.
