COLD CHAMBER DIE CASTING

cold chamber casting is extremely suitable for metals with high melting points
such as aluminum. In this process, the metal is liquefied in an extremely high
temperature furnace, and then sent into the cold room to be formed into the
mold.

In the cold chamber process, the content of molten metal should exceed the
required amount of the casting body, and the metal is pushed into the mold by a
hydraulically operated piston.

Cold Chamber Die Casting Capability
The earliest cold chamber die casting machine can be traced back to 1920, which
was first invented and manufactured by Carl Roehri. This cold chamber die
casting machine was separated from the furnace and the machine. When the molten
metal in the furnace was poured into the pressure chamber by hand (charging
barrel), there is a punch immediately to inject the molten metal into the mold.
Then, while the casting is ejected, the remaining biscuit formed by the excess
metal in a cold chamber die casting machine is taken out with the casting. It
can be seen that even with the current standards, this is completely a typical
cold chamber die casting process.

Advantages of cold chamber die casting
Three aspects: Dimensional accuracy, surface accuracy, thin wall. The
dimensional accuracy of castings is high.

Mass production: High productivity. Easy to realize mechanization and
automation.

Surface treatment: Easy to do various surface treatments, such as
electroplating, spraying.

Advantages of cold chamber die casting
Cold Chamber Die Casting Alloy
Cold chamber die casting can be used when die-casting metals that cannot be
used in the hot-chamber die-casting process, like aluminum alloys. In this
process, the metal needs to be melted first in a separate crucible. Then a
certain amount of molten metal is transferred to an unheated chamber or nozzle.

Quality Control of Cold Chamber Die Casting
In the production process, a strict quality control system and a perfect defect
management process must be established to ensure that various process elements
are within the normal range.

It is especially important to establish a quality information system, implement
priority processes for quality control, and improve product quality records,
statistics, analysis and feedback.


FAQs of Cold Chamber Die Casting
Q: What is the difference between cold chamber die casting and hot chamber die
casting?
The difference between hot chamber die casting and cold chamber die casting is
only in the pouring mechanism. The pressure chamber of the hot chamber die
casting machine is connected to the furnace, while the pressure chamber of the
cold chamber die casting machine and the furnace are separate.

Q: What is the Role of Cold Chamber Die Casting?
Cold chamber die casting can die-cast all kinds of castings from simple to
quite complex. Die-casting products are widely used in automobiles, aerospace,
telecommunications equipment, medical equipment, electrical instruments, and
daily hardware.

Q: Which Metals are Suitable for Cold Chamber Die Casting
Cold chamber die casting technology is suitable for metal die casting of
aluminum lloys. The press chamber is placed vertically. After the molten metal
is poured into the press chamber, the gas is on the top of the molten metal,
and less gas is involved during the molding process.
