A Brief Analysis of V-Method Casting

V-method casting originated in Japan, and got a good development in the 1980s. Seven or eight second-hand production lines have been introduced into China. Today, there are still 64 production lines in Japan, large or small, engaged in V-method casting. The materials include cast steel, cast iron, cast aluminum and cast copper. The casting types are mainly hydraulic components, military products, precision castings and colored artworks.

V method has good surface finish, high dimensional accuracy, low production cost, energy conservation and environmental protection, but not all of these advantages are reflected in the same casting at the same time, so do not easily give the advantages of V method in some castings to any casting; For any casting, there are often many molding methods. How to choose it is often because of some special advantages of a certain process.

We have achieved certain results in the production of traditional counterweights, bathtubs, piano skeletons and other few castings. However, in the application of most other castings, such as railway castings, mine wear-resistant, automobile chassis accessories, engineering machinery casting steel, etc., the expected output target has not been achieved. Even in the whole process of our operation, the advantages of energy conservation, environmental protection and low cost that are widely believed have not been brought into play, so it is necessary to have a clear understanding and accurate positioning of V method. The constituent elements of V method casting project engineering are not only the two concepts of equipment and auxiliary materials, but also a complementary whole of equipment, materials, processes, products and management. How to ensure product quality, how to achieve production efficiency, how to select and customize auxiliary materials and auxiliary tooling, how to reduce costs, how to solve environmental impact, etc., we need to carry out the operation of the project from beginning to end with these problems.
