Precious metal machining method

Abstract

The invention discloses a precious metal machining method. The precious metal machining method comprises the following steps that (1) a drawing is drawn; (2) a hollowed component of jewelry is manufactured; (3) a wax piece is bonded; (4) electroforming is carried out; and (5) finishing treatment is carried out. According to the precious metal jewelry machining method, a precious metal raw material is carved and cut through high-energy lasers, a carved accessory and a wax mould piece are welded, and then the wax mould piece and a welded precious metal piece are placed in an electroforming cylinder together to produce the precious metal jewelry in an electroforming pure gold forming manner. The product quality is improved, and the process problem that fine hollowed portions cannot be formed for jewelry produced through traditional 3D hard gold electroforming is solved. The precious metal jewelry manufactured through the machining method is fine in process, attractive and elegant, and product market competitiveness is improved.

Description

technical field [0001] The invention relates to a metal processing method, in particular to a precious metal processing method. Background technique [0002] In the jewelry industry, the use and processing of precious metal materials, there is a technology that is to smear conductive silver oil on the wax piece, put the wax piece into the electroforming cylinder and form a certain thickness on the surface of the wax piece through chemical reaction. The gold layer is formed, and then dewaxed to dissolve all the wax in the middle of the jewelry to form a precious metal jewelry. The product shape of this craft is full and vivid, but the whole product cannot form a hollow shape, and the aesthetics is greatly reduced, because most manufacturers in the entire jewelry industry use traditional crafts to produce jewelry, so the homogeneity of styles is very serious, so The process that can be improved is also slightly perfected on the basis of the traditional process, and has failed...

Problems solved by technology

The product shape of this craft is full and vivid, but the whole product cannot form a hollow shape, and the aesthetics is greatly reduced, because most manufacturers in the entire jewelry industry use traditional crafts to produce jewelry, so the homogeneity of styles is very serious, so The process that can be improved is also slightly improved on the basis of the traditional process, and has failed to break through the production mode of the traditional process, so the existing technology needs to be improved and developed
