  • Method for back-molding cold-shaped glass components using plastic
    Patent number: 11826934
    Abstract: A method for continuously molding glass components with the aid of at least one plastic, at least one unshaped glass component being positioned between a first molding tool and a second molding tool, the at least one unshaped glass component being elastically shaped by pressing together the first molding tool and the second molding tool, the at least one elastically shaped glass component being secured in the shaped state by locking slides, and a plastic being applied to at least one side of the shaped glass component at least in areas.

  • TOOL FOR OVER-MOULDING AND/OR BACK-MOULDING A CURVED GLASS BODY, AND METHOD FOR OVER-MOULDING AND/OR BACK-MOULDING A CURVED GLASS BODY
    Publication number: 20220032514
    Abstract: A tool for overmoulding and/or backmoulding a curved glass body is proposed, the tool having a first surface for supporting the curved glass body. The tool comprises a plurality of pins, the pins each having a first end face at a first end of the pins, and at least one section of the first surface being formed by the first end faces of the pins. The pins are mounted to be displaceable in their longitudinal direction so that at least the section of the first surface can be adapted to a contour of the curved glass body.

  • METHOD FOR COATING A SUBSTRATE WITH ALUMINIUM-DOPED ZINC OXIDE
    Publication number: 20130203211
    Abstract: A method coats a substrate with an aluminum-doped zinc oxide. The method includes generating a nucleation coating between 5 nm and 400 nm thick and having zinc oxide or doped zinc oxide, in particular aluminum-doped zinc oxide, on a surface of a substrate by atomizing a solid target. A quasi-epitaxially propagating top coating is generated and contains an aluminum-doped zinc oxide on the nucleation coating and the top coating is wet chemically etched.
