Vacuum Cold Chamber Die Casting Machine is a type of die casting equipment specifically designed to
produce high-quality metal castings under vacuum conditions. Here are some of its key features:
1.Cold Chamber Design: Unlike hot chamber die casting machines where the molten metal is stored in a
crucible within the machine, cold chamber machines have a separate furnace or melting furnace to melt
the metal before it is injected into the die.
2.Vacuum System: These machines are equipped with a vacuum system that removes air and gas from
the die cavity before and during the injection of molten metal. This helps in reducing porosity and gas
defects in the castings, leading to improved casting quality.
3.High Pressure Injection: Vacuum cold chamber die casting machines typically have high-pressure injection
systems to force the molten metal into the die cavity with precision and speed. This ensures that the cavity
is completely filled, resulting in accurate and detailed castings.
4.Temperature Control: Effective temperature control systems are employed to regulate the temperature
of the molten metal and the die during the casting process. This helps in achieving consistent casting
quality and reducing thermal stress on the die.
5.Automation and Control: Modern vacuum cold chamber die casting machines are often equipped with
advanced automation and control systems. These systems enable precise control over the casting process
parameters such as injection pressure, injection speed, die temperature, and vacuum level, ensuring
consistent and repeatable casting results.
6.Versatility: Vacuum cold chamber die casting machines are capable of casting a wide range of metal
alloys, including aluminum, magnesium, and zinc alloys. This makes them suitable for various industrial
applications where high-quality castings are required.
7.Quality Assurance: Vacuum cold chamber die casting machines are designed to produce high-quality
castings with minimal defects. The vacuum system helps in reducing gas porosity and shrinkage defects,
resulting in castings with improved mechanical properties and surface finish.
