ABSTRACT:
Molten metal is prevented from cooling too quickly when supplied to an injection sleeve of a casting device by applying a heat insulating powder onto an inner surface of the injection sleeve between each supply of molten metal. The heat insulating powder can be applied to the inner surface of the injection sleeve by way of an electrostatic field created between an electrode which has been inserted into the injection sleeve and the injection sleeve itself.
