Abstract

The invention discloses a making method for metal zipper teeth. The making method includes the following steps: S1, a step of material selection, namely the step of selecting metal powder as a raw material; S2, a step of molding, namely the step of calculating required density and pressure during making according to the dimensions of metal zipper teeth, referring to the dimensions of the metal zipper teeth and the raw material characteristics of the metal powder to calculate a contraction ratio, and designing a mold with a required zipper teeth shape; S3, a step of pressing, namely the step ofperforming pressing on the metal powder through the mold so that pressed metal zipper teeth can be obtained; S4, a step of sintering, namely the step of performing sintering on the metal zipper teethobtained by the step S3 through a sintering furnace; and S5, a step of polishing, namely the step of selecting different grinding equipment and grinding materials to perform polishing according to the physical properties of the metal powder material, and finally obtaining a finished product of the metal zipper teeth. The metal zipper teeth made by the method has characteristics of corrosion resistance, exquisite appearance, ageing resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing, and more specifically relates to a method for manufacturing metal zipper elements. Background technique [0002] Metal zipper plays a pivotal role in the zipper industry. Due to its superior texture and high-grade metallic luster, it is often used in bags and clothing. [0003] With the increasingly stringent quality requirements for the appearance and performance of metal zippers for luxury luggage and clothing, the zippers of traditional crafts have short service life, rough appearance, and easy oxidation and corrosion of materials, which are not enough to meet the requirements of modern people. [0004] Therefore, how to provide a method for making metal zipper elements with corrosion resistance, beautiful appearance and long service life is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the present invention prov...
