What Are the Advantages That Vacuum Die Casting Can Provide?
Die casting is the process of injecting molten metal into the cavity of a metal mold, holding it long enough to fully solidify, and then releasing it; it is used in a wide variety of industries, most commonly the automotive and commercial industries. Most industries that require high-quality parts choose vacuum die casting over traditional die casting methods. Some of the major industries that like to apply vacuum die casting are automotive, aerospace, electronics, marine, military, telecommunications, medical, etc. Vacuum die casting is popular in leading industries with its numerous advantages. So what are the advantages that vacuum die casting can provide?
Ⅰ. Advantages of vacuum die casting process
1. Reduce defects. This is an important reason why the vacuum die casting process is superior to the traditional die casting method. Often many types of defects occur during the die casting process. Vacuum die casting can greatly reduce or even completely eliminate different types of casting defects and improve the quality of manufactured parts.
2. Improved mechanical properties. Vacuum die casting reduces defects and makes melt distribution uniform. This ensures better integrity of the part and improves mechanical strength. It also allows your parts to be heat treated to improve certain properties.
3. Better surface finish. Another charm of vacuum die casting is that the finished part has a very good finish. This minimizes the need for additional surface treatments and helps you reduce the production cost of your parts.
4. Dimensional stability. Traditional die casting often fails to correctly produce parts with undercuts and thin walls. Rayforce vacuum die casting can overcome these limitations and allow these critical geometric parameters to be provided.
5. Short cycle time. Vacuum die casting allows rapid casting at high pressure without compromising quality. This helps reduce production time as no other post-casting operations are required for vacuum die casting.
Ⅱ. How to reduce pores in vacuum die casting?
Porosity is the pores or voids formed during vacuum die casting. It is usually formed due to trapped air or gas in the mold cavity. This also happens when there is a lot of dissolved gas in the melt released during solidification. There are other reasons for the formation of pores in castings. Such as turbulence during melt casting or vacuum holes due to metal shrinkage. Vacuum die casting can greatly reduce the chance of voids due to trapped air in the mold cavity. Because the air and gas present in the cavity are removed using a vacuum pump.
