  • Process for making reusable tooling
    Patent number: 8137607
    Abstract: A reusable, low investment tool for making parts is made by a process in which a mixture of sand and an activator is applied as a layer onto which a printed resin is deposited to form a base and a pattern. A plurality of sidewalls may also be provided on the base using the same process. The tool is coated with a curable resin to form a protective shell. The reusable tool may be used as a dump box or as a vacuum forming tool for forming parts. A stamping die may be formed by drawing a vacuum through the sand layer as the resin coating is applied to more fully permeate the stamping die.

  • Method of venting a spray metal mold
    Patent number: 7350558
    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.
