A tool for stamp-forming thermoplastic components may include a frame reinforced by an infill material. The infill material (e.g., cast ceramic) is configured to provide compression resistance to the frame and to insulate the frame from heat. A forming plate is coupled to the frame, and the plate has a front face defining a forming surface of the tool. One or more inductive heating elements are configured to heat the plate, wherein each of the one or more inductive heating elements comprises a conductor (e.g., Litz wire) coupled to a susceptor material (e.g., Invar<sup>®</sup>), and the one or more inductive heating elements are configured to be self-regulating with respect to temperature.
