The production process of gold-plated jewelry typically involves several steps. Here is a general outline of the process:
- Design: The jewelry design is created by a designer or a team of designers. This involves creating sketches, computer-aided design (CAD) models, or using specialized jewelry design software.
- Wax model or 3D printing: In some cases, a wax model of the jewelry piece is created using traditional carving techniques or 3D printing. This model will serve as the basis for the mold.
- Mold making: A mold is created based on the wax model or the 3D printed model. The mold can be made from materials like silicone, rubber, or metal. The mold ensures that the final jewelry piece is accurately replicated.
- Wax injection: The mold is used to create wax replicas of the jewelry piece through a process called wax injection. Molten wax is injected into the mold, filling its cavities and creating an exact replica of the original design.
- Tree assembly: Multiple wax replicas are attached to a wax rod, forming a tree-like structure. This assembly simplifies the later steps of the process by allowing multiple pieces to be processed simultaneously.
- Investment casting: The wax tree is then coated with a ceramic shell through a process called investment casting. The ceramic shell is built up layer by layer, creating a solid mold around the wax replicas.
- Burnout: The ceramic shell, with the wax replicas inside, is heated in a furnace. The high temperatures cause the wax to melt and evaporate, leaving behind a cavity in the shape of the jewelry piece within the ceramic shell.
- Quality control: The final step involves inspecting the jewelry piece for any defects, ensuring that it meets the desired quality standards. This may include checking for uniform gold plating, proper finishing, and overall aesthetic appeal.
