Abstract
A die-casting method that eliminates the need to inject insulation. By injecting molten metal sufficiently quickly after injecting tip lubricant, die-cast products may be removed from the mold even without injecting isulation. To this end, a movable die may at least begin moving toward a fixed die before tip lubricant is injected. The tip lubricant may be injected from a molten metal pouring port in a shot sleeve or from the movable die toward the shot sleeve. Tip lubricant which has been introduced into the shot sleeve is conveyed into the die cavity by movement of the molten metal, thus coating the die cavity inner surface.
