Die Casting is the preferred manufacturing process for casting metal products. There are two main types of the die casting process and many process options. When thawed metal is pressed under high pressure into the cavities of the teeth of a mold, it is understood as die casting. The process is best suited for the rapid fabrication of bulky metal parts that require little post-production processing.
Various die casting methods
Most types of die casting processes are designed with the same purpose: die casting using die casting. Depending on the type of dissolved metal, the geometry of the components, and the scaling of the components, different die casting procedures can yield exceptional results compared to alternative approaches. The two main types are hot cells and cold cells. Varieties of these two types of die casting include low-pressure casting, vacuum casting, and semi-solid die casting.
Hot focus camera
In some cases, known as “gooseneck die casting, “the hot chamber is the most popular of the two die casting processes. In this process, the canister chamber of the casting mechanism is completely immersed in the molten metal bath. The gooseneck metal feed program draws the molten metal into the die cavity.
Although direct immersion in the molten bath allows for quick and convenient injection of the mold, it also increases susceptibility to spoilage. Because of this, the hot cell process is best suited for applications that use low melting points and high fluidity alloys. Suitable alloys for hot chamber die casting include copper, zinc, lead, and magnesium.
Cold chamber method
The cold chamber pressure die casting process is very similar to the previous one. In a style that aims to reduce equipment oxidation rather than production efficiency, molten metal is processed immediately or by hand. It eliminates the need to submerge the firing system in a molten metal bath.
The cold cell can be an excellent alternative for applications that are too aggressive for the immersion-type hot cell process. These things melt metals with high melting points, such as metal-aluminum alloys.
Vacuum die casting is a reasonably new die casting process that offers superior durability and low porosity. A vacuum can form in the cylinder chamber, requiring molten metal to enter the mold’s tooth cavity. The process is similar to low pressure casting, except that the sections of the die casting and the molten metal bath are swapped. Vacuum casting is beneficial for products intended for post-casting heat treatment.
Low pressure system
Low pressure die casting is the process best suited for rotationally symmetrical aluminum components. For example, car tires are often made from low-pressure molded parts. In this process, the mold is placed vertically above the molten metal bath and attached through a riser. As the chamber seals, the metal is pulled up and into shape.
The compression process has been developed as a convenient means of melting metals and materials with low fluidity. In this procedure, molten metal fills a wide-open die, compressed, forcing the metal to penetrate the recessed portions of the mold. The compression molding process makes it possible to obtain very dense products and is also a technological process.
