Abstract: This is directed to connecting two or more elements using an intermediate element constructed from a material that changes between states. An electronic device can include one or more components constructed by connecting several elements. To provide a connection having a reduced or small size or cross-section and construct a component having high tolerances, a material can be provided in a first state in which it flows between the elements before changing to a second state in which it adheres to the elements and provides a structurally sound connection. For example, a plastic can be molded between the elements. As another example, a composite material can be brazed between the elements. In some cases, internal surfaces of the elements can include one or more features for enhancing a bond between the elements and the material providing the interface between the elements.

Abstract: This is directed to providing a cosmetic finish on a component constructed by connecting several elements. A single manufacturing process, such as machining or grinding, can be applied to the connected elements to remove material from some or all of the elements and to form a smooth and continuous surface across interfaces between the individual elements of the component. In some cases, settings of the material removal process can be adjusted based on the material of the component elements. For example, the settings can be adjusted based on the manufacturing or mechanical properties of each element material.
