DIE CASTING - PROS AND CONS

July 27, 2018

Die casting is really a process where molten metal needs under high pressure into mold cavities. The metal hardens to secure a desired shape. These days, plastic molded parts have replaced die-casting, as is also cheaper and lighter than die cast parts. Die-casting can be done employing a cold chamber or hot chamber process.

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

Good Die Casting. In the old times 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 over 4500 pounds per square inch. Initially, only tin and lead were die caste, however magnesium, copper and also other alloys may also be to cast using this highly popular process.



Die Casting Process. On this process molten metal or any other materials have no choice but, under underhand to the cavities from the steel mold. Dies are two part molds that are created from alloy tool steel - The fixer die half along with the ejector die half. The die or mold is fabricated with the idea of the ingredient that is usually to cast. You can find four kinds of dies:

Single cavity to generate one component
Multiple cavity to create a amount of identical parts
Unit die to create various parts previously
Combinations die to create several unique parts to have an assembly

The molten metal is injected in to the die under questionable and speed, which helps in creating a casting that is smooth and precise as the original mold. The pressure is maintained for the mold before the hot metal solidifies. Once the metal is hardened, the die is opened to get rid of the casting.
