ABSTRACT:
A method of cleaning a vulcanizing mold including the steps of providing, independently from a vacuum processing bath, a furnace for generating a plasma flow mainly containing neutral active species by a microwave discharge applied for a reactive gas; introducing the plasma flow in the processing bath and jetting it to the entire residue adhering surface of the mold positioned in the processing bath; and ashing residues by the jetted plasma gas. With this method, uniform ashing can be performed for residues adhering on the surface of a vulcanizing mold, without any adverse effect exerted on the mold.
