The electroplating process of 3D hard gold is mainly to use electroplating technology to plate gold on the mold, while the jewelry of hard gold is mainly to plate metal on the wax mold, and then put it into the electroplating instrument for electroplating.
After electroplating, 3D hard gold adopts high-precision wax pattern, advanced space dewaxing technology, no solder joints, one-step molding, and the surface lines are seamless, smooth, perfect and very three-dimensional. Therefore, the complexity of the process has also become the reason for the high unit price of 3D hard gold.
Traditional gold is soft in texture, so it has certain limitations in design. It can only do simple graphic design, but hollowing out and twisting are difficult to do. Handicrafts made of ordinary physical gold are small in size, heavy in weight and expensive, but inconvenient to wear. 3D hard gold broke through this limit.
Extended data
The difference between ordinary pure gold and pure gold bracelet 3D;
1, the manufacturing process is different. Thousands of pure gold, 999 gold and 99 gold are produced by traditional production technology, and 3D hard gold is produced by electroforming mode.
2. Hardness and toughness are different. The hardness of 3D hard gold is four times that of traditional pure gold, which is equivalent to 18K gold jewelry. High wear resistance, delicate and light, comfortable to wear. It breaks through the limitation of soft texture of gold jewelry, far exceeds the hardness of traditional gold, is not easy to wear, scratch and deform, has a stronger three-dimensional effect and is easier to maintain.
3. Comparison of styles and shapes. First of all, the difference between the starting mold. 3D hard gold jewelry is made from wax mold. Wax sculpture is exquisite and meticulous, and 3D modeling can be boldly used to make it fully play in 3D space, which is very stereoscopic. Traditional pure gold ornaments use low-temperature metals (such as lead and aluminum). ) to cultivate. Low-temperature metal is not easy to process and carve, and it is easy to leave solder joints and seams, so the shape is rough, almost all of them are near-plane reliefs, and the three-dimensional sense is poor.
