Abstract
An improved squeeze casting process is utilized to produce metal castings having superior mechanical properties. The process is particularly adapted for use in a vertical casting machine and is characterized by vacuum ladling, vacuum evacuated mold cavities, low metal temperatures, small metal feed gates and high gate velocities, application of high metal pressure on the metal filled cavity through the feed gate, and short processing times. When applied to aluminum alloy casting the squeeze casting process produces metal castings that can be heat treated at high temperatures to improve their mechanical characteristics.
