Vacuum Casting (V Process) Casting of Alloy Steel and Cast Iron

The following metal could be cast by vacuum mould casting:

• Carbon Steel: Low Carbon Steel, Medium Carbon Steel, High Carbon Steel
• Alloy Steel: CrMo Alloy Steel, High Mn Alloy Steel, SiMn Alloy Steel etc
• Stainless Steel, Duplex Stainless Steel, Precipitation Hardening (PH) Stainless Steel
• Cast Iron: Grey Cast Iron, Ductile Cast Iron, Malleable Cast Iron etc.

V Process (Vacuum) Casting Procedures

• The pattern is covered tightly by a thin sheet of plastic.
• A flask is placed over the coated pattern and is filled with dry sand without bind.
• The second flak is then placed on top of the sand, and a vacuum draws the sand so that the pattern can be tight and withdrawn. Both halves of the mold are made and assembled in this way.
• During pouring, the mold remains under a vacuum but the casting cavity does not.
• When the metal has solidified, the vacuum is turned off and the sand falls away, releasing the casting.
• Vacuum molding produces casting with high-quality detail and dimensional accuracy.
• It is especially well suited for large, relatively flat castings.

The Advantages of V-Process Casting

• The vacuum castings have high dimensional accuracy, clear outline and smooth surface.
• There are no binders, water and additives in the molding sand, which makes the sand processing simple.
• It is simple to clean the vacuum castings. Less harmful gases are generated during the casting process.
• The vacuum castings could be used at a wide range of industries. It can be used for single-piece small batch production as well as mass production, especially large and medium-sized castings and thin-walled castings are more suitable for vacuum casting.
