What is die casting?
Die casting is an automated casting process that forces liquid metal under high pressure (150 to 1200 bar) into a mold cavity at a high filling speed. This type of casting offers uniform quality to the component produced. it is typically used when a high volume of production and when quality, a consistent part is needed.
It is known as one of the quickest and most economical casting processes. And can produce a hundred of thousands of casting of the same item using one mold, offering equal quality to the items.

As earlier mentioned, the die-casting process is suitable for multiple and mass production of components. It is better and faster than sand casting, due to the demolition of mold when bringing out the casting.
Applications of die casting
The applications of die casting are most suitable for casting medium-sized parts with complex details. The technique is often performed on nonferrous metals like magnesium, aluminum, etc. Die casting is one of the largest casting methods that is used to manufacture consumer, commercial, and industrial products like automobiles, toys, parts of the sink faucet, connector housing, gears, etc.
