Die Casting Manufacturing Services
Die casting process uses a split metal tool die where molten metal is injected at high pressure. The cast part is ejected from the tool die by ejector pins on one of the tool die halves. Die casting is best where high production, accuracy, smooth surfaces and intricate small parts are desired. Only non-ferrous materials are die cast, such as aluminum-, zinc-, magnesium, and copper-based alloys.
Manufacturing production rates of 20-200 pieces/hr-mold are typical. The maximum mass limits for magnesium, zinc, and aluminum parts are roughly 4.5 kg, 18 kg, and 45 kg, respectively; the lower limit in all cases is about 30 g. Die injection machines are generally large (up to 3 X 8 m) and operate at high pressures - 1000 kg/cm2 and higher, although aluminum usually is processed at lower pressure. Set-up or lead time for die tools ranges from 6 to 10 weeks, after which a properly designed die tool set can produce over 500,000 castings during the production lifetime.
Die casting is a process commonly used in the mass production of non-ferrous metal parts. The most notable of products manufactured using the die casting process is match-box cars and other toys.
