The invention relates to a one-step forming manufacturing method of a bracelet, comprising the following steps of: enabling a manually carved
water channel to pass through two designed bracelet silver frame accessories, forming a glue film with a
wax injecting port in the middle of a surface through gluing pressure, and taking out silver frames; placing the glue film into a double-faced clamp plate with a through hole in the middle of the surface, injecting liquid
wax, condensing and then taking out formed
wax patterns, splicing the wax patterns together to form an integral bracelet wax pattern; repeating the front two steps to produce the bracelet wax pattern with multiple pattern types, and
welding liquid wax channels of a plurality of bracelet wax patterns together by using an electric
soldering iron; sleeving the plurality of bracelet wax patterns with iron bell models, injecting liquid
gypsum, and carrying out vacuum condensation; placing the
gypsum models into a high temperature furnace for thorough burning so as to form hollow
gypsum models; placing the hollow gypsum models into an air suction
machine, injecting
liquid metal, cooling, and then forming; and smashing gypsum to obtain finished products. The method has the
advantage that the bracelet is cast in one step, thereby not only saving time and cost, but also manufacturing bracelets with uniform patterns.
