Problems solved by technology

[0003] At present, most gold ornaments are manufactured by casting, oil pressure and other methods. It is difficult to obtain three-dimensional shapes for gold ornaments processed according to these aspects. Especially when processing hollow ornaments, it is not only difficult to form, wastes raw materials, but also easy to deform. As a result, hollow gold ornaments will be deformed when subjected to slight pressure during daily wear and use, and it is difficult to return to the original shape after deformation, which affects wearing and use

Embodiment 1

[0023] A method for processing hollow gold jewelry, comprising the steps of:

[0024] (1), adopt tablet press machine to press gold bar into the gold flake that thickness is 0.2 millimeter;

[0025] (2), by the method for electrolysis, add potassium cyanide, the gold flake of step (1) is processed into potassium gold cyanide;

[0026] (3), by the method of centrifugal casting, make the low-temperature alloy of the shape of required jewelry;

[0027] (4) Put the low-temperature alloy in the electroforming cylinder, add potassium gold cyanide, and electroplate for 12 hours. After the weight required for the jewelry is electroplated on the outer layer of the alloy jewelry, open 2 small holes;

Abstract

The invention discloses a method for manufacturing hollow gold ornaments. Compared with traditional casting and oil pressing methods, the method has the advantages that the weight of gold ornaments manufactured with the method is reduced by two thirds, the size of manufactured gold ornaments is larger, and a three-dimensional shape can be obtained. Gold ornaments manufactured with the method have excellent compressive strength, can be assembled, worn and used conveniently and have a longer service life, and the gold ornament repair cost is reduced.

Description

technical field [0001] The invention relates to a processing method of jewelry, in particular to a processing method of hollow gold jewelry. Background technique [0002] Gold ornaments are one of the favorite ornaments of people. In order to increase the ornamental value of gold ornaments, it is necessary to process different angles on the surface of gold ornaments or process gold ornaments into different three-dimensional shapes, so that they can present the same color under different angles of light. Effect. [0003] At present, most gold ornaments are manufactured by casting, oil pressure and other methods. It is difficult to obtain three-dimensional shapes for gold ornaments processed according to these aspects. Especially when processing hollow ornaments, it is not only difficult to form, wastes raw materials, but also easy to deform. As a result, when the hollow gold jewelry is worn and used in daily life, it will be deformed under slight pressure, and it is difficul...
