Multi-colored zipper and manufacturing method thereof

Abstract

The invention discloses a multi-colored zipper and a manufacturing method thereof. The method comprises the steps that 1, first-time coloring treatment is conducted on the peripheral surfaces of a Y-shaped brass tooth thread by adopting an electroplating technology, and a first coloring treatment layer is formed on the tooth thread; 2, after zip arranging treatment is conducted on the Y-shaped brass tooth thread treated in the first step, multiple zip teeth are formed, the electroplated first coloring treatment layer is formed on the front side end face and two edge side end faces of a tooth holder of each zip tooth, and a brass inner core of the Y-shaped brass tooth thread forms the upper end face and a tooth head of the corresponding tooth holder; 3, second-time coloring treatment is conducted on the zip teeth treated in the second step by adopting an oxidation or chemical plating technology, a second coloring treatment layer is formed on the upper end face and the tooth head, formed in the brass inner core, of the corresponding tooth holder, and the color and luster of the first coloring treatment layer is different from that of the second coloring treatment layer. By means of the multi-color design of the zip teeth of the zipper, the appearance of the zipper is novel and exquisite, the zipper is a product manufactured through the simple technology, the color and luster are stable, the color fastness is good, and therefore the product is good in quality and high in grade.

Description

technical field [0001] The invention relates to a zipper structure and a manufacturing method thereof, in particular to a metal zipper with chain elements in various colors and a manufacturing method thereof. Background technique [0002] At present, most of the metal zippers in the zipper industry are colored by a single oxidation, which is characterized by the consistent color of the teeth of the entire zipper. In order to solve the problem of the single tooth color of the chain teeth, there is also a kind of colored slide fastener in the market, please refer to CN98126362.3 "colored slide fastener and its manufacturing method and device" disclosed in the Chinese patent document on 1999-11-17. This product separates the molding material delivery path from the molding material supply part of the forming unit joint element to the injection port of the metal mold and the molding material delivery path from the metal mold injection port to the forming groove of the unit engage...
