Part 1: Introduction to V-Process Casting and ASUZAC ACM’s Expertise
In modern foundry technology, achieving precision, surface quality, and environmental responsibility has become a global challenge. Traditional casting methods—such as green sand or chemically bonded sand—have limitations when it comes to dimensional accuracy, surface finish, and environmental impact. To overcome these constraints, the V-process (Vacuum Process Casting) was developed.
Today, the V-process is recognized worldwide as a reliable and sustainable solution. At the forefront of this innovation is ASUZAC ACM, a global leader in aluminum casting manufacturing. With advanced facilities in Vietnam and strong Japanese engineering roots, ASUZAC ACM has become a pioneer in applying V-process technology to deliver precision aluminum castings for industries across Asia, Europe, and beyond.
This article provides an in-depth introduction to V-process casting, its fundamental principles, advantages over traditional methods, and the reasons why ASUZAC ACM has emerged as a trusted partner for high-quality aluminum castings.

What is V-Process Casting?
V-process casting is a molding method that uses vacuum pressure to form sand molds without chemical binders. Instead of relying on water or resins to bind the sand, the V-process employs:
- Dry, unbonded silica sand.
- Thin EVA plastic films, heated and vacuum-sealed over patterns.
- Vacuum pressure to harden the sand mold.
This process eliminates the need for chemical binders and produces molds with exceptional stability. The result: castings with excellent surface quality (Ra 12.5) and high dimensional accuracy.
Historical Context and Evolution
The V-process originated in Japan in the 1970s and was quickly adopted in industries that required large, precise, and environmentally friendly castings. Its binder-free nature made it especially attractive in markets facing stricter environmental regulations.
ASUZAC ACM, leveraging its Japanese technology background, introduced and refined the V-process in Vietnam to serve a rapidly industrializing Asian market. Today, ASUZAC ACM is one of the few foundries in Southeast Asia capable of high-volume aluminum V-process casting, positioning itself as an industry leader.

Advantages of V-Process Casting
1.Superior Surface Finish and Dimensional Accuracy
The tight adhesion of film to the pattern creates molds with excellent surface smoothness and sharp edges. Typical surface roughness achieved is Ra 12.5, significantly better than green sand molds.
Dimensional tolerances are also more consistent, reducing the need for secondary machining. This translates into lower costs and shorter lead times for customers.
2. Environmentally Friendly Process
Unlike resin-bonded or chemically hardened sand systems, V-process uses no chemical binders. The sand remains clean and can be recycled almost indefinitely. This drastically reduces waste and eliminates harmful emissions, aligning with modern environmental regulations.
For ASUZAC ACM’s clients, this ensures compliance with international sustainability standards and contributes to green manufacturing goals.
3. Flexibility in Design and Materials
V-process is suitable for all metal types—including steel, iron, and non-ferrous alloys. However, ASUZAC ACM focuses on aluminum alloys, due to their lightweight strength and corrosion resistance.
This allows ASUZAC ACM to support industries where reducing weight is critical, such as:
- Automotive manufacturing.
- Railway components.
- Industrial machinery.
- Consumer products.
4. Economic Benefits
- Reduced binder and material costs: no need for resins or chemicals.
- High yield rates: reduced scrap and rework.
- Sand reusability: significant savings in raw material consumption.
In addition, ASUZAC ACM provides pattern design optimization and CAE simulation analysis to improve gating systems, shrinkage compensation, and yield efficiency—ensuring customers receive cost-effective yet precise castings.
