Manufacturing methods that combine molding processes and shaping processes are described. The systems and methods described can be used to form composite parts using a single manufacturing process. In some embodiments, the methods involve positioning a workpiece within a mold cavity, then injecting a moldable material within the cavity at pressures sufficient to deform the workpiece such that features, such as protrusions or cavities, are formed within the workpiece. The resultant composite part includes the workpiece molded to a molded material. In some embodiments, the workpiece is a layer of metal material and the molded material is a structurally rigid plastic material, such that the composite part is a structurally rigid plastic with a metal coating. In some embodiments, multiple workpieces are molded within a composite part.
