Abstract
In a method for making a cast product by squeeze casting using an AZ91D alloy, the AZ91D alloy is heated to a liquid state, a shot sleeve is filled with the liquid AZ91D alloy, and a seal is formed between the shot sleeve and a die. In addition, the liquid alloy is injected into the die with an injection unit at a pressure of greater than about 69 Mega Pascal (Mpa) and a gate velocity of less than about 500 millimeters per second (mm/sec) and the AZ91D alloy is solidified in the die to generate the cast product.
