Cold chamber die casting is a preferred manufacturing process for metals that have high melting points, and it’s used by most of the top parts manufacturers in the industry. Typically, this will include metal alloys of aluminum, brass and copper. Cold chamber machinery requires additional equipment — usually an outside furnace and a ladle to pour the metal into the machine — for die casting. However, this allows the process to use materials that may be stronger and have versatile industry applications.
Molten metal must be ladled into the chamber directly, either through a ladle system or manually. Once the molten metal is loaded to a sufficient volume, it will be injected into the die through a high-pressure hydraulic plunger. Pressure requirements for cold chamber castings are typically higher than those of hot chamber die castings.
Cold chamber die casting can also take as short as seconds for the die to solidify, though other simple designs take just a few minutes. Cold chambers are typically built to contain multiple cavities, so different machine parts can be created at the same time — either duplicates or a variety of different parts in the same mold.
