Die casting is a method of manufacturing a metal part by adding a molten metal to a cavity under high pressure. In general, these molds or cavities are made of hardened tool steel which is preformed into a net shape or a near net shape of a die cast. The die-casting process also produces small details, such as texture surfaces or names, without further processing.

The ability to produce high-precision and high-precision parts makes die casting an ideal choice for mass production. The moment you wake up is the product that is surrounded by the die-casting process. When you turn the faucet, you can open the door handle, and when you drive, almost every product or part of the product you use in your daily life is produced using this process.

The die-casting process typically uses the main non-ferrous metal to produce the parts. Over the years, many different alloys have been developed to meet certain types of requirements and requirements for each application.

Hot chamber die casting is the name of the process of immersing the injection system into the molten metal pool. After that, the mold will open and the parts will be ejected. The advantage of this process is its short cycle time because it does not require metal to be transported from a separate furnace. Unfortunately, this die-casting process is only suitable for alloys that do not erode injection cylinders such as zinc, magnesium and copper.

Cold chamber die casting is the use of ladle to transfer molten metal from the holding furnace to the unheated spray chamber or injection cylinder. The metal is then sprayed into the mold by using a hydraulic piston. The main drawback of this method is that it is slower than the hot chamber die casting process. However, this method is mainly used for the manufacture of aluminum parts because the molten aluminum alloy has a tendency to erode and erode metal cylinders, plungers and molds, which greatly shortens its service life.
