Die casting is done by introducing molten metal into the mold at high or low pressure. Molds are well designed to give complex products with stunning accuracy and smooth finishing. They are made of high quality steel as steel has higher melting point. You can reuse these molds for almost thousands of times. Casts can be single cavity that produces only a single component, multiple cavity that produces multiple identical parts at a time, unit die that produces different parts and combination die that produces different parts in one go. Usually zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys are used for die casting.

Using die casting we can make products with pore-free products that do not allow gas to pass though them and making them strong. Two types of machines are used for die-casting. Cold-chamber and hot-chamber die-casting.

Die casting is an economical yet effective process of creating a broad range of shapes. It is better than other manufacturing technique and is durable and aesthetic, merging seamlessly with the other parts of the machinery of which it is a component. Die casting can deliver complex shapes with high levels of tolerance than any other mass production methods. Identical castings can be mass produced in thousands before you are required to add any new casting tools.

Having the metals in high pressure is the most common way to cast many other metal alloys, representing about 50% of all production. The low method, on the other hand is used only about 20% of the time for only special products, yet its usefulness increases within time. Other methods are gravity die casting - which amounts to the remaining percentage of production with only a little less left for recently introduced processes - squeeze die casting and vacuum die casting.

Die casting provides parts that are durable and dimensionally stable in nature. While providing complex shapes of industrial parts within closer tolerances, it eliminates or reduces secondary machining operations. Die cast parts have greater resistance to temperature extremes. Marked as one of the fastest and most cost effective method for producing a wide range of components, it has become the most commended force of metal industry. Being vital to many manufacturing industries like automotive, whitegoods, hardware, electrical and electronics, computers and many others it provides components in aluminum, zinc and magnesium alloys efficiently, accurately with good mechanical properties and consumer appeal.
