Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A tire mold or a tire mold segment can include an air compression cavity, which connects to multiple surface connection slots having dimensions between 10 and 300 microns, which can be suitable for selective removal of air in the mold. The air compression cavity, can be close to the outside ambient, allowing the air escaping the interior of the mold to be compressed, which can assist in preventing the rubber material from leaving the mold pattern surface.

A liquid-jet-guided laser system can be used to generate functional slots having different depth and sidewall profiles by applying active control of laser beam parameters. Blinds slots can be processed onto a workpiece, such as a tire mold or a turbine vane, for an insertion of a sipe or a sealing element, respectively. Through slots can also be processed onto a workpiece, such as a turbine element for cooling during operation or a semiconductor wafer for singulation purpose. The processing of the workpiece can include a two-step procedure, wherein the first step comprises a pre-cut. The pre-cut cuts a contour outline of a slot onto a workpiece corresponding to an element that is to be inserted into the slot. The second step comprises a removal cut to remove excess workpiece material in between the contour outline. The liquid-jet-guided laser system can employ multiple-wavelength processing of a multiple-material workpiece.

Provided is a turning and milling system, comprising: a work platform comprising a first drive mechanism; a rotating platform, said first drive driving said rotating platform to rotate on the said work platform and drive a workpiece to rotate about a vertical axis; a blade assembly comprising a blade and a second drive mechanism connected to the blade; said second drive mechanism drives the blade to move in the horizontal direction, changing the machining radius of the blade.

Methods and structures for forming anodization layers that protect and cosmetically enhance metal surfaces are described. In some embodiments, methods involve forming an anodization layer on an underlying metal that permits an underlying metal surface to be viewable. In some embodiments, methods involve forming a first anodization layer and an adjacent second anodization layer on an angled surface, the interface between the two anodization layers being regular and uniform. Described are photomasking techniques and tools for providing sharply defined corners on anodized and texturized patterns on metal surfaces. Also described are techniques and tools for providing anodizing resistant components in the manufacture of electronic devices.
