costume jewelry wholesale uk Introduction to 3D hard -footed gold crafts
has always been cast with gold jewelry mainly using the Casting and stamping molding method. However, since 1993, China, Hong Kong, and Taiwan have adopted the use of electrical casting methods () to cast thinner jewelry. Comparing the above two casting methods, the advantage of the power casting is that less gold can be used to make more three -dimensional and larger volume proportions, so as to achieve the effect of light, low price and generous decent.
The power casting uses a current to restore the metal ions in the casting solution into metal atoms. During the golden power casting process, gold ions were restored to golden atoms by current chemistry by current, and were deposited on the surface of cathode waxy parts. You can take it out of the power casting solution, and then drill the holes in order to dissolve the wax and use the heat nitric acid to clean the power casting workers. After cleaning and cooking with water, it becomes a power casting product. Finally, it is processed to polish After that, you can become a power cast product.
3D hard gold technology is the improvement and invention of the golden power casting process. It mainly improves the gold content, pH value, working temperature, organic optical agent content and stirring speed in the casting solution. Improve the hardness and abrasion of gold. This process is unique that the hardness of the gold jewelry is high (4 times the hardness of Victoria's hardness), strong abrasion resistance, and the gold content can still ensure that it is more than 999th of thousands of thousands. , High hardness and abrasion -resistant hollow gold products.
