Abstract: A mold core package for forming a molding tool includes a plurality of stacked particulate layers having a binding agent. The plurality of stacked particulate layers form sacrificial walls defining a mold cavity. A sacrificial displacement line and a sacrificial displacement body extend from the mold core package and are adapted to displace a molten material applied to the mold core package.

Abstract: A mold core package for forming a molding tool includes a plurality of stacked particulate layers having a binding agent. The plurality of stacked particulate layers form sacrificial walls. An elongate sacrificial displacement line extends through the mold core package adjacent a forming surface of the mold core package. A mold cavity is defined by the stacked particulate layers.

Abstract: A method comprising the use of additive manufacturing techniques for creating molds and pattern parts for subsequent use in the casting of die components and die shoes for use in die stamping processes.

Abstract: A powder slush molding tool having heating and cooling features cast as part of the tool, wherein the tool created using molds formed by additive manufacturing techniques, and wherein the tool is further used for making a flexible polymeric soft skin for use in a vehicle interior.

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.
