A method for manufacturing a resin molded stator may include: preparing a straight winding core in which neighboring partial core backs are coupled by a joint; bending the core at joints and causing distal ends of teeth to face an outer peripheral surface of a core metal to obtain a core metal assembly including a stator mounted on the core metal, arranging the core metal assembly in a mold; injecting resin into the mold, covering windings with resin, curing the resin; and removing the stator from the mold and the core metal. The core metal may include a plurality of ribs projecting outward from the outer peripheral surface, the number of the ribs being between three and the number of the teeth. Each rib may extend parallel to a center axis, and each rib may be located in a gap between the distal ends of adjacent teeth.

An article of manufacture having an in-molded resistive and/or shielding element and method of making the same are shown and described. In one disclosed method, a resistive and/or shielding element is printed on a film. The film is formed to a desired shape and put in an injection mold. A molten plastic material is introduced into the injection mold to form a rigid structure that retains the film.

A method for producing at least one plastic component (1), wherein in the method the following steps, preferably in the following sequence, preferably cyclically in the following sequence, are carried out: a) providing at least one film (2) and at least one sensor film (3), wherein the at least one film (2) and/or the at least one sensor film (3) has at least one thermoplastic material or at least one thermoplastic polymer; b) applying the at least one sensor film (3) to at least one first region of a surface of the at least one film (2); c) forming the at least one film (2) having the at least one sensor film (3), wherein one or more formed film bodies (4) are made; d) punching out one or more film elements (4a) made from at least one second region of the one or more formed film bodies (4), and a device (10) and a plastic component (1).
