A method for infiltrating a water-proof material into a zipper, includes the steps of combining an upper mold with a lower mold, filling a liquid polyurethane (PU) rubber into the mold cave of the upper mold, drawing the zipper through the underside of the mold cave such that the liquid PU rubber will infiltrate into the fabric of the zipper tapes, passing the zipper through a scrapper portion formed at the lower edge of the upper mold to remove surplus liquid PU rubber, and forming a laminate on the zipper tapes, so as to accomplish a water-proof zipper.
