  • Publication number: 20140272121
    Abstract: A replica 3D structure is fabricated inside a multi-layered mold by patterning each mold layer to define a void/opening that matches a corresponding cross section of the structure's peripheral surface, and filling the patterned opening of each layer with a structural material (i.e., before depositing a subsequent layer of mold material). The mold material (e.g., photoresist or another dissolvable sacrificial material) is blanket deposited (e.g., by slot-die, spray coating) and then patterned using a laser or a printed mask. Each layer of modeling material (e.g., polymer, ceramic or metal, or a combination thereof) is electro-plated or otherwise deposited on the previously formed modeling material layer. High vertical resolution is achieved by utilizing relatively thin mold layers. The mold layer deposition, patterning and modeling material deposition is repeated until the replica 3D structure is entirely formed inside the multi-layered mold, and then the mold is dissolved or otherwise removed.

The mold has a barrier coating intimately bonded to one or more surfaces of the mold that repels the attraction of the embedding material to the one or more mold surfaces and produces a positive meniscus of the embedding material in the mold. The barrier coating permits the mold to be re-used without needing to manually re-apply a release agent to the mold before using the mold. Further, the barrier coating permits the use of more aggressive draft angles than conventional molds by reducing the frictional engagement between the embedding material and the mold cavity surfaces.

    Abstract: A method for making a master mold used to nanoimprint patterned magnetic recording disks that have chevron servo patterns with minimal defects uses directed self-assembly of block copolymers. A pattern of chemically modified polymer brush material is formed on the master mold substrate. The pattern includes sets of slanted stripes and interface strips between the sets of slanted stripes. A block copolymer material is deposited on the pattern, which results in directed self-assembly of the block copolymer as lamellae perpendicular to the substrate that are formed into alternating slanted stripes of alternating first and second components of the block copolymer. This component also forms on the interface strips, but as a lamella parallel to the substrate. One of the components is then removed, leaving the remaining component as a grid that acts as a mask for etching the substrate to form the master mold.

  • Patent number: 8808794
    Abstract: The present invention relates in general to a method of manufacturing fibre-reinforced parts for a wind power plant, such as a blade, in an open mould. More specifically the invention relates to a process step of applying at least one layer of gelcoat on a interior surface of said open mould prior to arranging at least one layer of material comprising fibre and to an arrangement that can be used in performing said method. The process step comprises to apply the gelcoat from a first end portion of the mould and to a second end portion of the mould and to cover the open mould from said first end portion to said second end portion gradually as gelcoat is applied. The arrangement comprises means for applying gelcoat to the interior surface of the mould (1) and a covering means (6) arranged to gradually cover the open mould (1) as gelcoat is applied.

    Abstract: A multi-layer coating for a glass-shaping mold is disclosed. The multi-layer coating may include a glass-contacting layer and a diffusion barrier layer. The glass-contacting layer may make contact with glass during glass-shaping and may include titanium oxide, aluminium oxide, or combinations thereof. The diffusion barrier layer may be positioned between the glass-contacting layer and a mold body and may restrict diffusion of base metals from the mold body to the glass-contacting layer and diffusion of glass materials from the glass-contacting layer to the mold body.

  • Patent number: 8778452
    Abstract: A mold for the formation of an over cladding layer in an optical waveguide is integrally produced from a light-transmissive resin and a light-transmissive support plate by molding using a mold member identical in shape with the over cladding layer. In the production of the mold, a hollow resulting from the removal of the mold member serves as a cavity for the formation of the over cladding layer. For the formation of the over cladding layer, the cavity of the mold is filled with a photosensitive resin for the formation of the over cladding layer, and the photosensitive resin is cured by being exposed to light through the mold while cores formed in a pattern on a surface of an under cladding layer are immersed in the photosensitive resin.

  • Patent number: 8778451
    Abstract: A method of manufacturing an optical waveguide is provided in which a mold that prevents fins or burrs from being formed is used for the formation of an over cladding layer in the optical waveguide. The mold for the formation of the over cladding layer is produced from a light-transmissive resin by molding using a mold member including a protruding portion identical in shape with the over cladding layer and a ridge portion provided around the protruding portion. For the formation of the over cladding layer, the cavity is filled with a photosensitive resin for the formation of the over cladding layer, and the photosensitive resin is cured by being exposed to light through the mold while cores formed on a surface of an under cladding layer are immersed in the photosensitive resin and part of the photosensitive resin spilling out of the cavity is collected in the groove.
