Hot Chamber Vs Cold Chamber Die Casting

The die-casting process is so efficient that it is often used in large quantities to make parts of all shapes and sizes common in our lives and workplaces. The die casting process produces parts with smooth, textured surfaces that do not need to be polished. The two most common die casting methods are hot chamber and cold chamber. When you understand the differences between the two die casting methods, you can more specifically choose the right parts manufacturing partners to help you with the production and production of products. Let me introduce the advantages and disadvantages of each type of die casting for you.

Basic knowledge of die casting machine cold chamber

In general, cold chamber die-casting is preferred for high melting point metals, a method used by most of the industry's top parts manufacturers, including common metal alloys such as aluminum, brass, and copper. Die casting machine has aluminum cold chamber die casting machine, brass vertical die casting machine, alloy die casting machine and so on. Cold chamber machinery requires additional equipment - usually an external furnace and a ladle to pour metal into the machine - for die casting. This special process can use high strength materials and has a wide range of industrial applications.

The molten metal must be poured into the chamber either through a ladle system or manually directly using the ladle. Once the molten metal has been loaded in sufficient quantities, it will be plugged into the mold via a high-pressure hydraulic cylinder. In general, the pressure requirements of cold chamber die castings are usually higher than those of hot chamber die castings.

Compared with the cheap aluminum die casting machine, our lead die casting machine can solidify the mold in a shorter time. Cold cavities are usually built to contain multiple cavities, so that different machine parts can be made at the same time -- either duplicated in the same mold, or different parts made separately in different cavities.

Understand hot chamber die casting

The hot chamber die casting machine uses an alloy crucible as part of the machine, and at the same time uses a goosenc to inject material from the crucible into the mold. The internal mechanism of the machine pairs the plunger and port to control the amount of molten metal.

When the end is sealed, the metal cools and solidifies in the chamber. When the mold is opened, the plunger retracted to remove the casting. This design makes the hot chamber die casting a continuous process.

Hot chamber die casting machine is suitable for materials with low melting point. Materials selected are also limited to those that do not corrode or dissolve machine metals at high temperatures or pressures. The materials used in hot chamber die casting are usually zinc, lead and magnesium alloys.
