A vacuum system or Vaccum Technology in die casting refers to the equipment and technology used to create a vacuum in the cavity during the casting process. The vacuum system removes air and gasses from the mold cavity during filling, reducing the risk of defects in the final casting. The mold is sealed within the chamber, and the air is removed through channels and valves.
Benefits: The benefits of using a vacuum system in die casting include improved casting quality, reduced porosity, and improved mechanical properties of the finished casting. Additionally, the vacuum system allows for the casting of complex shapes with thin walls and intricate details, which would otherwise be difficult to achieve using conventional casting methods.
A vacuum system can also reduce casting cycle times and improve overall productivity.
Application: Vacuum systems can be used in a variety of die-casting processes, including high-pressure die casting, low-pressure die casting, and gravity die casting. However, the specific design and operation of the vacuum system may vary depending on the particular die-casting process and the requirements of the final product.
Here are some new developments in the vacuum technology field:
This involves vacuuming from both mold and shot sleeve. It shows a considerable reduction of gas porosity, especially in the gate area. It also improves shot velocity consistency by reducing resistance.
This is for critical and safety-sensitive castings that have very stringent porosity requirements. You need to maintain a vacuum of sub-50 millibar levels within the cavity. All points in the mold and leakage points must be sealed thoroughly for it to be effective.
Actuation of vacuum is required nearest to the mold for large die-casting machines. This reduces actuation time and losses in creating a vacuum. Some makers like Fondarex and Raga Group have come up with solutions for modular vacuuming. The modular or extension units are mounted on the platen. The units actuate vacuum and also take inputs through measurement of gas sucked.
