Die Casting - Pros And Disadvantages

July 27, 2018

Die casting is often a process through which molten metal needs under high pressure into mold cavities. The metal hardens to get a desired shape. Recently, plastic molded parts have replaced die-casting, since they are cheaper and lighter than die cast parts. Die-casting is possible employing a cold chamber or hot chamber process.

About Die Casting Process. Die casting is a widespread non-expendable technique by which metal have no choice but in the mold cavity under underhand. Die casting mold which are generally known as dies can be used repeatedly to produce castings in several sizes, shapes and wall thickness. The mold cavities are designed with intricate designs that permits in producing complex shapes with accuracy, surface finish and attractiveness..

Good Die Casting. In the past of die casting only low-pressure injection method was applied, however nowadays high-pressure casting techniques like squeeze casting and semi-solid die casting methods are use to cast more than 4500 pounds per sq . inch. Initially, only tin and lead were die caste, but now magnesium, copper and also other alloys can also be to cast applying this highly popular process.



Die Casting Process. With this process molten metal or another materials have, under ruthless into the cavities in the steel mold. Dies are a couple of part molds which can be created from alloy tool steel - The fixer die half and also the ejector die half. The die or mold is fabricated believing of the component that would be to cast. There are four varieties of dies:

Single cavity to produce one component
Multiple cavity to make a number of identical parts
Unit die to produce different parts at once
Combinations die to produce several unique parts for an assembly

The molten metal is injected in to the die under high pressure as well as speed, which assists in creating a casting that’s smooth and precise because original mold. Pressure is maintained about the mold before the hot metal solidifies. If the metal is hardened, the die is opened to eliminate the casting.
