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.
