ABSTRACT:
The present invention relates to a novel method of venting a spray metal molding surface. More particularly the invention relates to a method of manufacturing a mold using a thermal spray process to produce a metal surface containing passages in the spray metal to vent fluid or gas from the forming surface. The present invention is primarily intended for mold tools, such as vacuum molds, injection molds or blow molds having vents or a multiplicity of holes in the forming surface to evacuate or supply gas in a mold.
