What is aluminum alloy die casting?
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. Aluminum die casting is that it creates lighter parts—with more surface finishing options than other die cast alloys. Aluminum can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast aluminum is versatile, corrosion resistant. It retains high dimensional stability with thin walls and can be used in almost any industry. Aluminum can also withstand the highest operating temperatures of all the die cast alloys.
How are Aluminum Die Castings Made?
The aluminum casting dies that are created using hardened tool steel must be made in at least two sections so that castings can be removed. The aluminum die casting process is able to produce mass aluminum castings in quick succession. The dies are firmly mounted in the die casting machine. The fixed half die is stationary. The other one, injector die half, is movable. Aluminum casting can be simple or complicated, with movable slides, cores or other parts, depending on the complexity of the casting. To begin the die casting process, the two die halves are clamped together by casting machine. High temperature liquid aluminum alloy is injected into the die cavity and rapidly solidified. Then the half movable die is opened and the aluminum die casting is ejected. Up to now, the aluminum die casting has been the fastest cycle to produce precision aluminum parts. This is in stark contrast to sand casting, which requires new sand molds for each casting. Although the permanent mold process uses iron or steel molds instead of sand, it is much slower and less precise than aluminum die castings.
