摘要

A method of manufacturing a shell element (13) for an electronic device, said shell element (13) having a front (5) and at least one part that is angled in relation to said front (5). The shell element (13) further comprises a formed sheet (6) that constitutes at least a part of the outer surface of said front (5) and at least a part of said part that is angled in relation to the front of the shell element (13). The method comprises the steps of first forming a sheet (1) to a desired shape including a part that is angled in relation to a front part (5) and then injection moulding a plastics material on the back of the formed sheet (6). At least one area of the angled part of the formed sheet (6) is provided with an undercut (7) at the latest during injection moulding of the plastics material on the back of the formed sheet (6). A shell element manufactured by this method is also disclosed.
