  • Publication number: 20150072110
    Abstract: The present invention is a method that (i) allows for creating micro and/or nanostructures on either planar or non-planar three-dimensional surfaces in a single molding step, and (ii) allows for the molded production of complex high-aspect ratio micro and/or nanostructures including but not limited to cylinders, conical structures, low aspect-ratio channels, bumps, or posts. An example of such a complex structure are high aspect ratio pillars with enlarged “mushroom-shaped” or undercut tips which demonstrate enhanced, repeatable adhesion and shear strength on a variety of substrates when compared with other micro and/or nanostructures and unstructured materials. The mold of such a material requires an “undercut” feature that cannot be produced using typical micro/nano-molding processing techniques.

  • Patent number: 7780891
    Abstract: A tire mold having a substantially elliptical base surface and a method for making a tire mold are provided. In one embodiment, a user selects a major axis length for the tire mold, then selects a ratio of the major axis length to a minor axis length. The tire mold is then formed with a substantially elliptical base surface defined by the first major axis and the selected ratio.

  • Patent number: 7666336
    Abstract: The invention relates to a method for producing monolithic molded elements e.g. as sorbents for chromatographic columns or capillary vessels. The aim of the invention is for said molded elements to be able to remain directly in the gel mold thereof following the production process. Said aim is achieved by the inventive method, according to which the surface of the gel mold is activated by etching, increasing the surface, or chemically modifying the surface before the gelling mold is filled with the monomer sol.

  • Patent number: 7648661
    Abstract: A system and method for making and using a reconfigurable composite part mandrel operable in the manufacture of composite parts. The system may comprise an assembly fixture, a generic mandrel, a reconfigurable simulated skin, a reconfigurable frame portion, and state-changing material operable to harden into a desired configuration for forming a particular composite part. The method of forming and using the reconfigurable composite part mandrel may comprise: inserting the simulated skin within the assembly fixture, inserting or assembling the frame portion within the assembly fixture; inserting the generic mandrel into the assembly fixture; filling a cavity between the generic mandrel and the assembly fixture with the state-changing mixture to encapsulate the frame portion; hardening the state-changing mixture; and removing the assembly fixture and the simulated skin.

  • Publication number: 20090108491
    Abstract: A mold image assembly includes a plurality of contact elements assembled in a defined space such that the contact elements are independently movable, with a first end of the contact elements collectively forming a first surface and a second end of the contact elements collectively forming a second surface. The first surface is adapted to be brought into contact with an object such that the first surface assumes an altered contour that substantially conforms to a contour of the object, and the second surface assumes a correspondingly altered contour. The contact elements are further adapted to be joined together to thereby secure the altered contour of the second surface as a mold image.
