ABSTRACT:
A die-casting method in which a lubricant is heated to a temperature higher than a temperature of mold cavity surfaces before molten metal is injected into the mold cavity. The lubricant is heated when the mold cavity is formed by bringing a movable mold into contact with a stationary mold. The heated lubricant is introduced into the mold cavity and applied on the mold cavity surfaces, and the molten metal is then injected into the mold cavity. The molten metal is allowed to solidify in the mold cavity to become a solidified article. A die-casting device for carrying out this method is also provided according to the present invention.
