METHOD FOR MANUFACTURING JEWELRY HAVING ANION AND FAR INFRARED RAY EMITTING FUNCTION BY COATING TREATMENT USING SPRAY NOZZLE

摘要

PURPOSE: A method for manufacturing a functional jewelry is provided to be economically and massively capable of producing a jewelry having delicate and various design and size with anion and far infrared ray emitting effect. CONSTITUTION: The method for manufacturing a functional jewelry comprises the steps of: forming a hollow product by press process; mixing a powder which emits anion and far infrared ray and a coating agent; injecting the mixture onto the hollow product through a nozzle of a compressed piston; and heat treatment of the mixture.
