Problems solved by technology

[0002] With the development of modern industry and high technology, the scope and style of jewelry, ornaments and decorations made of gold continue to expand and deepen. People have higher and higher requirements for the quality, appearance, and volume of gold ornaments. , the electro-gold process is a key stage. In the current electro-gold process, due to problems such as the gold content in the bath, the pH value in the bath, and the working temperature of the bath, the distribution of gold plating is uneven, the forming time is long, and the thickness Large, polarized bright suede often appears, the product is small in size, heavy in weight, and low in hardness

Embodiment Construction

[0008] The present invention specifically comprises the following steps:

[0009] 1. Carved wax plate

[0010] Make a physical model with wax clay according to the requirements of the drawing, requiring clear and distinct lines, fine products, and appropriate proportions;

[0011] 2. Open the plastic mold

[0012] After covering the surface of the physical model with silica gel, let it dry naturally, which is the rubber mold. Finally, the physical model is taken out from the rubber mold. During processing, the surface layer is required to be smooth and the joints are flat;

[0013] 3. Wax connection

[0014] Inject liquid wax into the rubber mold and fill it to the full. There is no space in the rubber mold until it solidifies and becomes solid wax. After peeling off the rubber mold, it is a wax piece;

[0015] 4. Waxing

[0016] Repair the surface of the wax piece with a repairing crayon, requiring careful selection to ensure that the repaired wax piece is consistent with...

Abstract

The invention relates to a processing technology of hard gold ornaments with the purity of 99.999 percent, the processing technology consists of the following steps of: wax plate carving, wax mold opening, wax connecting, wax repairing, oiling, gold plating, wax removing and quality inspection. The technique differs from the prior art of gold plating in that: LJJAS auxiliary agent is added into an electrolyte; the electroforming temperature is 50 to 60 DEG C, the electroforming speed is 0.05g / h, the pH value of the plating solution is between 7.0 and 70.5. Therefore, the gilt produced by the technology has the advantages of uniform distribution, strong covering capability, thin plating layer, short molding time, large volume, small weight, and high hardness, and is especially applicable for the gold ornament processing industry.

Description

technical field [0001] The invention relates to a gold processing technology, in particular to a processing technology of hard pure gold gold ornaments. Background technique [0002] With the development of modern industry and high technology, the scope and style of jewelry, ornaments and decorations made of gold continue to expand and deepen. People have higher and higher requirements for the quality, appearance, and volume of gold ornaments. , the electro-gold process is a key stage. In the current electro-gold process, due to problems such as the gold content in the bath, the pH value in the bath, and the working temperature of the bath, the distribution of gold plating is uneven, the forming time is long, and the thickness Large, polarized bright suede often appears, the product is small in size, heavy in weight, and low in hardness. Contents of the invention [0003] The purpose of the present invention is to provide a hard pure gold jewelry processing technology tha...
