Embodiment Construction
[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] The present invention is a method for making hollow metal jewelry. In this embodiment, a method for making a hollow ring is adopted, and the method includes the following steps:
[0017] Pre-design and manufacture wax injection molds. The wax injection molds are made of steel molds. The wax injection molds include a shape wax injection mold and a hollow wax injection mold. Ring shape grooves are made on the shape wax injection molds. Ring shape grooves can be designed for various rings Shape, making ring hollow die groove on hollow wax injection mould, the diameter of ring hollow die groove is smaller than the diameter of ring shape die groove.
[0018] The water-soluble wax is injected into the hollow mold cavity of the ring on the hollow wax injection mold to obtain the water-soluble wax mold of the hollow part....
