Method for Manufacturing A Watertight Zipper

Abstract

The present disclosure provides a method for manufacturing a watertight zipper for solving the problem of production difficulties. A method for manufacturing a watertight zipper according to the present disclosure includes: forming a waterproof tape by extruding a polymeric material in melted state wrapping around an outer surface of a cloth tape, cutting a side of the waterproof tape that is covered by the thick waterproof layer by laser to form a side surface of the thick waterproof layer in a plane form as an abutting surface, forming a plurality of apertures at the waterproof tape, wherein each of the plurality of apertures extends through the cloth tape and the thick waterproof layer, and forming a plurality of scoops corresponding to the plurality of apertures by injection molding. The waterproof tape includes a thick waterproof layer and a thin waterproof layer both formed by the polymeric material in solidified state. The thick waterproof layer covers a side surface, an upper surface and a lower surface of the cloth tape. The thin waterproof layer connects with the thick waterproof layer. Each of the plurality of scoops spaces from the thin waterproof layer. An end of each of the plurality of scoops extends beyond the abutting surface of the thick waterproof layer.
