What is V Process Casting?
The V process, short for vacuum process, is a cutting-edge sand casting technique that uses vacuum pressure to hold sand molds together without the need for chemical binders. This unique method offers a cleaner, more sustainable approach to casting and is ideal for producing components with complex geometries and smooth finishes.
Key Steps in the V Process Casting
- Pattern Preparation: A thin plastic film is placed over the pattern and heated to conform to its shape.
- Vacuum Application: Sand is packed tightly around the film, and vacuum pressure holds the mold together.
- Metal Pouring: Molten metal is poured into the cavity, and the vacuum ensures the mold’s stability.
- Cooling and Removal: Once the metal solidifies, the vacuum is released, and the mold collapses, leaving a high-quality casting.
This process results in fewer defects, smoother surfaces, and greater dimensional accuracy compared to traditional sand casting.
