What is Die Casting Machine?

Die casting is a metal molding process that forms castings of a certain shape and size by pressing molten metal into a mold. This process has the advantages of high productivity, low manufacturing cost, and high product accuracy, so it is widely used in the industrial field. Hot chamber die casting machine and cold chamber die casting machine are two types of die casting machine.


Hot Chamber Die Casting Machine

Die casting machine body, heating system, mold, control system, and additional parts make up a hot chamber die casting machine. Die casting cylinders, injection cylinders, ejector cylinders, and other parts make up the die casting machine's main body. The heating system heats the die casting material, the mold is the essential die casting component, and the control system is in charge of the automatic control of the entire die casting process. The hot chamber die casting machine operates on the principle of injecting molten metal into a closed hot chamber, heating it to a specific temperature using a heating system, and then using high pressure to inject the metal into the mold to form a variety of product shapes. 

Due to its high metal utilization rate, high production efficiency, and high-quality output, the hot chamber die casting machine is extensively utilized in the manufacturing of a wide range of metal products, including architectural hardware, machinery and equipment parts, automotive and electrical parts, and so forth. The hot chamber die casting machine is a significant piece of equipment for the production of metal products. Its development prospects are wide as it will continue to find applications in the manufacturing industry and the advancement of technology.


Cold Chamber Die Casting Machine

A cold chamber die casting machine quickly hardens liquid metal under high pressure and forms it into objects with predetermined dimensions. This machine is distinguished by its sophisticated high-precision inspection system, effective automated manufacturing, and die-casting technology. Its cold chamber design may offer a steady die-casting environment to guarantee the liquid metal's even distribution and quick solidification. The automated control system of the machine can achieve precise die casting control and high efficiency production capacity simultaneously, resulting in a significant increase in production efficiency. Furthermore, the cold chamber die casting machine's inspection system is excellent.
