  • Patent number: 11951289
    Abstract: A piston having a longitudinal axis and opposing proximal and distal axial ends is manufactured by a method including molding a partially formed piston body and then molding the piston. The partially formed piston body is molded by placing a first rubber sheet and an inert film between die plates of a first forming tool, vulcanizing the first rubber sheet and the inert film between the die plates of the first forming tool, and blanking out the partially formed piston body from the first rubber sheet and the inert film. The piston is then molded by placing the partially formed piston body into a second forming tool, placing a second rubber sheet into the second forming tool, vulcanizing the second rubber sheet and the partially formed piston body together, and blanking out the piston from the second rubber sheet at a trim edge spaced apart from the inert film.
