The invention relates to a metallic invisible zipper and a manufacturing process thereof. The metallic invisible zipper comprises cloth belts, wherein one side edge of each cloth belt is provided with a central line, and the cloth belts are provided with a plurality of chain teeth; each chain tooth comprises a main tooth body which is provided with a tooth ear; the main tooth body and the tooth ear are integrally connected with each other in a U shape; and the U-shaped chain teeth are arranged on the cloth belts in a manner of clamping the central lines. The metal invisible zipper is manufactured by the procedures of stamping, dotting, extruding, sewing, forming and the like. The chain teeth of the metallic invisible zipper are hidden on one surface of each cloth belt, so that the invisible function can be well realized; in addition, the structural strength of the metallic invisible zipper is higher than that of a nylon invisible zipper, and the metallic chain teeth are unlikely to fall; besides, the production of the metallic invisible zipper does not need a bending procedure, so that not only is the process step simplified and the production efficiency improved, but also the structure of zipper production equipment is simplified, the stability in product production is improved and the production cost is reduced.
Description
technical field [0001] The invention relates to an invisible zipper and its manufacturing process, in particular to a metal invisible zipper and its manufacturing process. Background technique [0002] The elements of invisible zippers currently on the market are all made of nylon. Metal elements and resin elements are limited by the way the elements attach to the zipper tape. The existing technology cannot produce metal zippers and resins with ideal invisible effects. Zipper: Because the structural strength of nylon zipper is smaller than that of metal zipper and resin zipper, the types of existing invisible zipper products cannot meet the needs of the market, especially the application on high-end products. [0003] In addition, the existing metal zipper manufacturing process mostly includes the following steps: feeding (element particles) → stamping (punching a gap along the middle of the long side of the element particles, so that the bent element particles fit better T...
