Die castings are formed by injecting molten aluminum under high pressure into steel molds called "dies". This process can provide a wide range of products because close tolerances can be consistently held and metal parts can be produced efficiently and at high rates of production. The die casting process produces parts that are cost-efficient and highly engineered.It brings flexible sizes and close tolerances. Die castings are used in a wide variety of industries, including Agriculture,Mining,Construction Equipment,Commercial Machinery and Tools,Communications, Office Equipment,Military,Aerospace,Railroad,Automotive,Lighting and Medical;etc.
A steel die is mounted to a die cast machine. The mating die halves are tightly locked together to withstand the high injection pressure of the molten metal. The molten metal is then injected into the die, the metal solidifies quickly and the part is ejected from the machine. Gates and flash are removed, and other secondary operations are performed as required. The process is repeated in rapid succession thus producing high quantities of accurate parts in a short period of time.
*Offering a broader range of shapes & sizes than other manufacturing technique: small to large, light to heavy and simple to complex.
*High-speed production: High production efficiency and labor costs are lower compared to other manufacturing processes.
*Dimensional accuracy and stability: Be durable and dimensionally stable, while maintaining close tolerances.
*Strength and Weight: Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.
*Multiple finishing techniques: Be produced with smooth or textured surfaces and they are easily plated or finished with surface preparation.
*Simplified assembly: Holes can be cored and made to tap drill sizes, or external threads can be cast. Cored holes and other features can be sized in a way to minimize or even eliminate machining and other secondary operations. In addition, various types of inserts can be cast in.
*Visual appeal: Die cast parts are aesthetically pleasing, have a long service life and may be designed to complement the visual appeal of the surrounding part. Designers can gain a number of advantages and benefits by specifying die cast parts.
