ABSTRACT:
A method for outsert molding a movable plastic part on a metal plate, wherein the movability is obtained automatically through the shrinkage of the plastic. The plastic part consists of a bridge element which traverses a hole in the metal plate and is integrally connected to opposing retaining elements by a film element. The size, shape, and rigidity of the film, bridge, and retaining elements are such that the forces produced during the shrinkage process lift the retaining elements off the metal plate.
