aluminum pressure die casting machine
Aluminum pressure die casting is ideal for metals such as aluminum which have a high melting point. During this process, metal is liquefied in a furnace at extremely high temperatures and then ladled into a cold chamber to be injected into the die.
Aluminum pressure die castings are used when working with alloys with high melting points, such as aluminum, brass, and magnesium. The transport of molten material is typically done using a ladle, which can be handled automatically or manually. Afterward, a hydraulically operated plunger seals off the pressure compartment and forces the metal into a die. These machines minimize the amount of heat, reducing the chance of corrosion in the plunger and its associated components.Casting cycles can range from 10 seconds for small die casting machines up to two minutes for larger units.
During aluminum pressure die casting, the molten charge, which consists of more material than is required to fill the casting, is ladled from the crucible into a shot sleeve where a hydraulically operated plunger pushes the metal into the die. The extra material is used to force additional metal into the die cavity to compensate for shrinkage, which takes place during solidification.
