Methods and systems for forming a dual layer housing

摘要

Methods and apparatus for applying internal features or complex mechanical structures to a surface of a metal part are disclosed. According to one aspect of the present invention, a method for creating an assembly that includes a substrate and a molded piece involves obtaining the substrate, and forming at least one binding feature on a surface of the substrate. The method also includes molding on a surface of the binding feature and the surface of the substrate. Molding on the surface of the binding feature and the surface of the substrate mechanically binds the molded piece to the substrate.

主权项

1. A method for creating an assembly that includes a substrate and a molded piece, the method comprising:
adding a layer of material over the substrate such that the layer of material includes perforations through an exterior surface of the layer of material; and extruding molten material onto the exterior surface and into the perforations such that the molten material engages with binding surfaces within the perforations, wherein the molten material hardens as the molded piece secured to the substrate.
