Embodiment 1

[0026] A kind of processing technique that purity is 999.99‰ inverted mold type gold jewelry, the steps are as follows:

[0027] (1) Plate making: divided into three types: manual plate making, 3D modeling laser resin forming machine plate making and eight-axis engraving machine plate making, the purpose of which is to make the original design into a silver plate;

[0028] (2) Open glue mold: Utilize the silver plate that step (1) makes, make the glue film that is used for injecting wax;

[0029] (3) Wax injection: Utilize the wax injection machine to align the wax injection holes with the film prepared in step (2) to obtain a wax model, and plant the wax film into a wax tree, and the mutual distance between the wax films is 5mm;

[0030] (4) Mold inversion: a. Take high-purity gold with a purity of 999.994‰ or more as a raw material, put the high-purity gold into a high-frequency furnace graphite pot to melt, pour it into a baked graphite tank, and use titanium as the gold ma...

Abstract

The invention belongs to the field of jewelry processing, and in particular relates to a processing technology for molded gold jewelry with a purity of 999.99‰. The present invention pays attention to the cleanliness of the environment in the preparation process, and uses the steel used in the process , Iron tools are replaced with diamonds, special tools, to avoid the reaction with the gold material, resulting in the loss of the purity of the gold material, and the gold jewelry with a purity of 999.99‰ is obtained, which greatly improves the quality, purity and ornamental value of the gold jewelry. user experience.

Description

technical field [0001] The invention belongs to the field of jewelry processing, and in particular relates to a processing technology for molded gold jewelry with a purity of 999.99‰. Background technique [0002] With the improvement of people's living standards, people's desire to buy gold jewelry is increasing day by day, and the requirements for the appearance, purity and quality of gold jewelry are also constantly improving. The existing jewelry processing technology uses molten gold with a purity of more than 999.994‰ as a raw material, but in the process of processing jewelry, the purity of molten gold is usually lost, resulting in the purity of the gold jewelry produced can only reach 99.99%. Manufacturers cause economic losses and cannot meet the needs of consumers. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a processing technology for molded gold jewelry with a purity of 999.99...
