ABSTRACT:
A method of manufacturing a super-thin advertising and decorative zipper tab, comprising the following steps:1) casting the first mold with one end of a soft string disposed therein;2) providing a sprue on the first mold at a position under the soft string before closing the first mold and injecting plastic to conjunct the soft string within the first molding blank; and3) placing the molding blank into a second mold such that a sprue is provided at a position above the soft string before closing the second mold and injecting plastic to conjunct half of the second molding blank with the soft string, in order to manufacture a super-thin advertising and decorative tab.In the position switch of the respective sprues of the first and second molds, by way of the theory of high pressure generated at the time of injecting plastic into the first mold, the soft string (or bend) can be positioned and integrally combined with the molding blank as desired; and by way of second injection of plastic to conjunct the first and second molding blanks into one completed advertising and decorative zipper tab which tallies with the requirement of a super-thin zipper tab.
