What Is High Pressure Die Casting?
High pressure die casting is a
manufacturing process that the molten metal is forced by high pressure into a
metal die cavity. A powerful press holds it until the metal solidifies. When
the metal solidifies, the die is unlocked and opened, the casting ejected.
After the casting is removed, the die is closed and locked aging for the next
round run. In high pressure die casting process, molten metal is injected by
high speed and high pressure into the mold. Horizontal High Pressure Die Casting machines ensure that the die is closed. The closing force can apply
ranging from 550 to 5700 tones.
Two types of system that used for injecting
the molten metal into the die include the hot chamber system and the cold
chamber system. Depending on the type of metal being used, the injection unite
can be either hot chamber or color chamber. The hot chamber system is normally
used with metals like zinc, lead and magnesium. The injection system of the hot
chamber machines is immersed in the molten metal. It forces metal through the
nozzle and into the die as the shot plunger moves. The cold chamber system is
used for metals which is melt in high temperatures such as aluminum, magnesium
and brass. Magnesium parts could be created by using the hot and the cold
chamber system. Cold chamber high pressure die casting is an ideal process to
produce a vast range of aluminum and magnesium automotive casting like gearbox
casing, engine blocks, engine mounts, structural parts, oil sumps. As hot
chamber machines have size limitation, small magnesium parts are produced in
hot chamber machines and large magnesium parts in cold chamber machines. Two
injection system used in the cold chamber process is horizontal and vertical
injection.
With high Pressure Die Casting, large light
alloy parts can be produced in large volume and high speeds. High pressure die
casting machines deliver light alloy parts with high precision, high quality
surface finish and excellent mechanical properties. High pressure die casting
process is able to build parts with thin walls and co-cast parts like screw and
liners.
