CNC Die Casting Engine Processing Shell Body / Die Casting Molds
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is
created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.
Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter and tin-based alloys. Depending
on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of
parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a
large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings
are characterized by a very good surface finish (by casting standards) and dimensional consistency.
Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc
castings to reduce scrap and increase yield.
Hot-chamber die casting
Hot-chamber die casting, also known as gooseneck machines, rely upon a pool of molten metal to feed the die. At the beginning of the cycle the
piston of the machine is retracted, which allows the molten metal to fill the "gooseneck". The pneumatic- or hydraulic-powered piston then forces this
metal out of the gooseneck into the die. The advantages of this system include fast cycle times (approximately 15 cycles a minute) and the
convenience of melting the metal in the casting machine. The disadvantages of this system are that it is limited to use with low-melting point metals
and that aluminium cannot be used because it picks up some of the iron while in the molten pool. Therefore, hot-chamber machines are primarily
ued with zinc-, tin-, and lead-based alloys.
