A technical device, such as an electromechanical deck for moving information carriers, includes a plastics function part molded into a deck plate by outsert-molding. The function part includes a bridge element, which traverses a hole in the deck plate, and retaining elements, which are situated at the deck plate surfaces and are interconnected by the bridge element, the plastics of said part being subject to shrinkage after injection-molding. The mobility of the function part as a rotatable or slidable part is obtained automatically despite shrinkage of the plastics part by positioning the retaining elements at each end of the bridge element so that they do not overlap, when viewed in the axial direction of the bridge, with a retaining element at the opposite end of the bridge.
