Forging consists of forging and stamping. Forging can eliminate as-cast porosity defects and optimize the microstructure of gold during melting. At the same time, because the complete metal streamline is retained, the mechanical properties of forgings are generally better than those of castings of the same material. Forgings are mostly used for important parts with high load and bad working conditions in related machinery except for simple rolled plates, profiles or weldments.
The change of gold jewelry from raw materials to jewelry, its initial process has three parts:
1. Recycled old gold ornaments are used as raw materials and melted into the iron trough to form gold bars.
Secondly, the next step is forging, that is, pressing the gold bars into gold plates according to the thickness of the required profiles.
Thirdly, the gold plate is forged for the second time, that is, the corresponding profiles are made according to the needs.
Wherein the oil pressure part processes the product prototype. The prototype is sent to the mold holding department for shaping, so that the shape of gold ornaments such as rings and bracelets is closer to the finished product.
The material preparation department processes and produces the prototype of products according to the mold, that is, semi-finished products or accessories, including necklace accessories, beads or olive beads. Then, these semi-finished products will be transferred to the chain to connect the accessories of the necklace, thus forming a preliminary complete necklace.
4. Finally, make a composition for the semi-finished jewelry car and polish off the unnecessary parts. Surface treatment, such as re-polishing, finished product weighing and product specification label registration.
