A vertical type pressure die casting process which is expected to have high accuracy, high reliability and high productivity was developed by the authors on the basis of the squeeze casting process. Aluminum castings made by this process have fine appearance, no internal defect and excellent strength. Heat treatment is possible. The high quality of the products is realized by the monitoring equipment installed in the system. Productivity and cost of this process are comparable to the conventional high pressure die casting process. By using this process, it is possible to manufacture aluminum die castings for pressure-tight parts and high strength components with sufficient reliability which was impossible with the conventional die casting process.
