Method of manufacturing anti-allergy alloy earring needles with excellent heat dissipation properties and high hardness without discoloration

摘要

The present invention relates to a method for manufacturing earring needles, and more particularly, in manufacturing earring needles using an alloy material having excellent heat dissipation properties and anti-allergic components, the material is manufactured in the form of an ingot and processed into a plate shape through rolling. It can be manufactured quickly without post-processing by forging plate-shaped material to increase strength and press-processing using a mold so that the edges are rounded on both sides of the earring needle after heat treatment. An object of the present invention is to provide a method for manufacturing anti-allergic alloy earring needles without discoloration of high hardness. To this end, the method for manufacturing an anti-allergy alloy earring needle having excellent heat dissipation characteristics and high hardness and no discoloration according to an embodiment of the present invention includes an ingot manufacturing step of manufacturing an ingot with a material for manufacturing the earring needle, in the ingot manufacturing step A rolling step of rolling the manufactured ingot-shaped material into a plate, a forging step of forging by striking the rolled material, a heat treatment step of heating the forged material to increase its ductility, and a double-sided press method of a material whose ductility is increased by heat treatment It includes a double-sided no-edge pressing step of cutting so that the corners are rounded using
