Embodiment Construction

[0022] The present invention will be further described in detail below in combination with specific embodiments.

[0023] The manufacturing method of the novel precious metal snow pattern of the present invention comprises as follows:

[0024] Step 1, melting the precious metal to make a precious metal block;

[0025] Step 2, using air pressure to mold the precious metal block;

[0026] Step 3, putting the cooled precious metal block into boiling sulfuric acid water for pickling, and cleaning the precious metal block after pickling;

[0027] Step 4, putting the cleaned precious metal block into boiling nitric acid water for pickling, and cleaning the precious metal block after pickling;

[0028] Step 5, performing electrolytic treatment on the surface of the cleaned precious metal block;

[0029] Step 6, cleaning the electrolyzed precious metal block.

[0030] Wherein, in order to further improve the manufacturing effect of the snow pattern, the snow pattern manufacturing ...

Abstract

The invention discloses a novel precious metal snowflake pattern manufacturing method. The novel precious metal snowflake pattern manufacturing method comprises the steps that precious metal is manufactured to be of the needed specification in a pneumatic casting forming mode, then acid pickling and electrolysis are carried out on the precious metal, and therefore the precious metal with snowflake patterns is formed. By means of the method, as the pneumatic casting forming is adopted directly on the precious metal, crystal lattices will not crack or regroup, namely the crystal lattices can maintain the basically consistent size, and the display effect of the snowflake patterns is greatly improved.

Description

technical field [0001] The invention relates to a method for manufacturing snow patterns, in particular to a method for manufacturing snow patterns of novel precious metals. Background technique [0002] Precious metal materials such as gold and silver are often used to make ornaments, but pure gold and silver jewelry will inevitably look tacky, so special processing is usually carried out. Among them, making snow patterns on the surface of gold and silver materials is a more common method; However, the existing snow pattern processing methods usually use one-time heating for heating. During the heating process, the crystal lattice of the precious metal will be broken and reorganized. However, due to various uncontrollability in the heating process, after reorganization The lattice size will be inconsistent, and the inconsistency of the lattice size will seriously affect the display effect of the snow pattern. Contents of the invention [0003] In order to overcome the de...
