Do you know what Die casting technology is?
In metal processing today, various casting processes are used to transform molten metals into specific shapes for commercial and industrial use.In each casting process, a cavity is formed.Liquid metal cast ED under gravity or high pressure.After a few seconds, the metal solidifies and the newly hardened casting is released from the mold or shape.
Die casting technology is most often employed to make intricate metal objects that would otherwise be complicated and much costlier to produce with different methods.
Die casting technology has been around since ancient times.Today, some of the earliest examples of metal casting exist in the form of jewelry, tools, and sculptures that have been excavated from archaeological sites and displayed in museums around the world.Early casting methods included gypsum mold casting and wax loss casting.
Today, the methods of casting fall into the non-expendable and expendable categories. Other variants of the two categories include the methods used to fill cavities — including pressure and gravity — and the material used to form a particular mold.
There’s the non-expendable type of casting, which would account for any method in which the mold can be used again. Examples of non-expendable casting include permanent mold and die casting methods, in which the molding cavities are made of metal. Non-expendable casting is often favored for its ability to produce uniform parts at high volumes.
Expendable die casting accounts for any method in which the mold is discarded after a single use. Examples in this category include sand and plaster die casting, in which molten metal is poured into a cavity that is then broken away to reveal a finished casting. A further example of expendable casting is investment casting, a modern version of lost wax casting, in which molds are formed around wax patterns, which are then melted away to reveal hard ceramic cavities for subsequent metal molding.
