Cold Chamber Machines vs. Hot Chamber Machines

The Concept

People who do not participate in this area usually have a general understanding of the gears. For many, you may only go as far as familiar with key terms, such as knowing that the template is referred to as death.

Expanding this concept may explain that the templates act as a variable element, and are injected with molten metal. This process is usually done under high pressure and exercise force to death. The molten metal can be injected in two different ways, and the difference between the two is referred to as hot and cold circuit processes.

Hot Chamber Machines

Hot room machines use a variety of metals, as long as they have a low melting point. The main factor of these alloys is that they will not destroy or weaken any part of the machine parts that come into contact with them during this process. When the metal is injected, it moves down the square and enters the hot chamber (usually a metal bowl hanging in a pool of molten metal). The port at the top of the device corresponds to the piston, dictating the amount of molten metal being poured.

When the port is closed, the metal settles into the cavity where it freezes, as soon as the piston retracts from the casting process to be ready for removal.

Materials Used: Alloys – Zinc, Copper, Magnesium, Lead

Temperature: Materials with low melting points

Chamber: Gooseneck

Closing System: Plunger

Process: Ongoing

Cold Chamber Machines

With molten alloy casting in the cylindrical screw, the hydraulic piston drives the alloy through the system and closes the hole in the cold chamber outlet. While the alloy is pasted, the molten metal is forced to the death cavity under high pressure. Depending on the product, the template may take a few seconds to stiffen, or even a few minutes (smaller products usually take a few seconds, while more complex products require longer waiting times, time depends on weight). The design of the refrigeration system contains multiple cavities that may contain multiple parts or different parts. This means that several parts, similar or different, can be made in one cycle.
