  • System and method for preventing warpage of metal components during manufacturing processes
    Patent number: 9283698
    Abstract: A method for manufacturing a component including a bi-metallic sheet includes performing a manufacturing process that heats the bi-metallic sheet and physically constraining the bi-metallic sheet from deformation during the cooling of the bi-metallic sheet. Optionally, the method additionally includes physically constraining the bi-metallic sheet from deformation during the manufacturing process that heats the bi-metallic sheet. A constraining apparatus is also disclosed and includes a first constraining component having a first thermally conductive contact surface adapted to abut a first surface of a metal sheet, a second constraining component having a second contact surface adapted to abut a second surface of the metal sheet, and an engaging device operative to fix the first constraining component and the second constraining component in position relative to one another. The metal sheet is constrained between the first contact surface and the second contact surface during heating and/or cooling.

  • Enclosure of anodized multi-layer metallic shell with molded plastic scaffolding and method of manufacture
    Patent number: 8681485
    Abstract: A device enclosure includes a clad metal shell having a plurality of mounting structures attached thereto. Methods for manufacturing the device enclosure are also disclosed. In a particular method, the mounting structures are formed on a surface of the clad metal shell by nano molding technology. Alternatively, the mounting structures are formed by molding before being attached to the clad metal shell by an adhesive.
