Method of manufacturing color metal zipper and apparatus therefor

Abstract

Method and apparatus of manufacturing color metal zipper are disclosed. The method includes washing half-finished metal zipper; overlaying a thin film on the upper surface of half-finished metal zipper; feeding color transfer paper; overlaying the half-finished metal zipper on the color transfer paper and positioning same; intermittently advancing the overlaid half-finished metal zipper and the color transfer paper; heating and pressing the overlaid half-finished metal zipper and the color transfer paper in an interval when the advancing stops for uniformly transferring color of the color transfer paper to a portion of the half-finished metal zipper; intermittently advancing the half-finished metal zipper and the color transfer paper again; separating the finished color metal zipper from the color transfer paper while intermittently advancing; and cooling and storing the finished color metal zipper and color transfer paper.

Description

technical field [0001] The present invention relates to a forming method and device for drawing colored metal. Background technique [0002] It is known that the zipper or refining rack made of metal materials can only show the color of the metal material, such as a single color such as metal color or gold, but in the current zipper application, it is not only It only provides the function of refining and closing the two separated objects into one or opening. It also pays attention to the integrity and color matching between the attached objects. Therefore, the zipper or refining rack with color will improve the overall decoration and matching. Novel visual effects. [0003] The known technology applied to the color zipper or its manufacturing method or its manufacturing structure can be roughly divided into the following types: [0004] 1. Manufacturing methods by injection molding, such as Taiwan Patent Gazette Nos. 36447, 286494, 379170 and 489013 and other patent cases...

AI Technical Summary

Problems solved by technology

[0004] 1. Manufacturing method by injection molding, such as Chinese Taiwan Patent Publication No. 36447, 286494, 379170 and 489013 and other patent cases, the above-mentioned patent cases all use the addition of color pigments to the materials used in injection molding, or use light Plastic materials mixed with sensitive or temperature-sensitive discoloration materials to form colorful colored zippers or chain racks, or more suitable for secondary processing surface color pouring or stuffing production, but the above-mentioned colored raw materials The injection method needs to reach a certain batch size before it can be put into production, otherwise the production cost will be very high, and when the production is completed or the color needs to be changed, it is necessary to completely clean the mold, injection machine, material cylinder, etc. without any material residue To avoid defective products that cause color mixing of some materials, which consumes a lot of cleaning time and labor costs

[0005] 2. Utilize printing and dyeing, spray dyeing, transfer printing or color coating manufacturing methods, such as patent cases such as China Taiwan Patent Publication No. 413621, 162482 and 150513, which are mainly used in zipper teeth made of nylon or plastic steel materials or Chain racks, using processes such as printing and dyeing, spray dyeing, transfer printing or color coating to produce metallic or colored surfaces, but the above methods are only applicable to chain teeth or chain racks made of non-metallic materials

[0006] 3. Utilize the manufacturing method of embedding coating, such as the new patent of "pitch type color zipper structure" in Taiwan Patent Publication No. 524064, the core that has been made into color is coated on the transparent color with the injection process. The inside of the tooth is refined to form a zipper structure. However, the core is mostly a thick yarn mixed with cotton and artificial fibers, which is soft and lacks rigidity. The inside of the chain, so the chain needs to be made of transparent materials. However, if the plastic zipper is made of PC material, it is easy to crack when it is cleaned with chemicals, and the polyester zipper needs to be used on the chain. It is sewn on the cloth belt with sutures. Although the sutures can also be made of transparent yarns, the color of the core must be covered by the transparency of the sutures and the chain itself, so that the visual effect of the colored zipper is not good. Of course, the production cost is also higher

However, the segmented etching treatment of chemical liquid can only produce the difference between dark and light colors, and cannot produce color vision, and the corrosive chemical liquid has problems such as waste liquid treatment and environmental protection.
