Abstract

A method of discriminating the quality of die-cast articles when casting an article by pressurizing and filling a molten metal into a die through an injecting sleeve by means of an injecting plunger, the method comprising the steps of: measuring at least one of the operational parameters of a die temperature, a gas pressure in a die cavity, a molten metal pressure in a die cavity, an injecting sleeve temperature, an injecting plunger travel speed, and an injection plunger displacement; and discriminating the quality of a die-cast article by comparing the measured parameter value with a reference value determined on the basis of a predetermined interrelationship between the operational parameter and an allowance limit of the amount of a casting defect. A die-casting process using the method is also disclosed.
