The Advantages and Applications of Vacuum Casting (V-Process Casting )

Vacuum casting process, also called V process casting, V-Process casting or vacuum moulding casting, is one type of dry sand casting and requires the use of air extraction equipment to extract the air inside the casting mold, and then use the pressure difference between the inside and outside of the mold to cover the heated plastic film on the patterns and the templates. The casting mold will become strong enough to withstand the molten metal during casting. After obtaining the vacuum casting mold, fill the sand box with dry sand without binder, and then seal the top surface of the sand mold with the plastic film, followed by vacuum to make the sand firm and tight. After that, remove the mold, put the sand cores, close the mold to make everthing ready for pouring. Finally, the casting is obtained after the molten metal is cooled and solidified.

The Advantages of V-Process Casting

The vacuum castings have high dimensional accuracy, clear outline and smooth surface.

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.

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.

Applications of Vacuum Castings

Parts made by vacuum casting are utilized to cast a wide variety of items, including high quality, high performance industrial parts of complex structures.

The application of the vacuum casting parts covers a wide range of industries, they are typically used in the following areas:

Rail Trains

Heavy Duty Trucks

Automotive

Agricultural Equipment

Hydraulics

Engine Systems

Construction Equipment

Logistics Equipment

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.
