Die Casting – Advantages and Disadvantages

Die casting is a process in which molten metal is forced under high pressure into mold cavities. The metal hardens to get a desired shape. In recent times, plastic molded parts have replaced die-casting, as they are cheaper and lighter than die cast parts. Die-casting can be done using a cold chamber or hot chamber process.China Continuous Casting Production Line for Billet/Round/Slab Caster -  China Rolling Mills, Steckel Mill

Die casting is a widespread non-expendable technique in which metal are forced into the mold cavity under high pressure. Die casting mold that are known as dies can be used repeatedly to produce castings in a variety of sizes, shapes and wall thickness sand casting company. The mold cavities are designed with intricate designs that enables in producing complex shapes with accuracy, surface finish and attractiveness..

In the early days of die casting only low-pressure injection method was used, but today high-pressure casting techniques like squeeze casting and semi-solid die casting methods are use to cast more than 4500 pounds per square inch. Initially, only tin and lead were die caste, but now magnesium, copper and other alloys are also to cast using this highly popular process.

In this process molten metal or other materials are forced, under high pressure into the cavities of the steel mold. Dies are two part molds that are made of alloy tool steel – The fixer die half and the ejector die half. The die or mold is fabricated with the impression of the component that is to cast. There are four types of dies:

Die casting is most suitable for casting medium sized parts with complex details. Die-casting is the largest casting technique that is used to manufacture consumer, commercial and industrial products like automobiles, toys, parts of sink faucet, connector housing, gears, etc. Most die castings are done from non-ferrous metals like aluminum, magnesium, etc.
