Metal die casting is a manufacturing process where molten metal is injected into a mold under high pressure, solidifying and taking the shape of the mold cavity. This method is commonly used for creating various components, including parts for machinery, automotive parts, and, in your case, medals.
When it comes to creating a gold-plated metal die-cast medal with a ribbon, the process typically involves the following steps:
1. **Die Design**: A custom mold is designed for the medal shape, which includes the medal's relief, edge, and any engravings or designs. The mold might also have cavities for attaching the ribbon.
2. **Metalcasting**: The mold is made of steel or another durable material, and the chosen base metal (usually zinc or aluminum) is melted and poured into the mold. The metal solidifies quickly, forming a rough casting.
3. **Cleaning and Inspection**: After casting, the medal is cleaned to remove any excess metal, mold release agents, or impurities. Inspections ensure the medal meets quality standards.
4. **Gold Plating**: The medal undergoes electroplating, where a layer of gold is applied through an electrolytic process. The thickness of the gold layer can vary depending on the desired finish and value.
5. **Engraving and Finishing**: Any necessary engravings or text is added using laser or mechanical engraving techniques. The medal may then be polished or buffed to achieve a bright, shiny appearance.
6. **Ribbon Attachment**: A separate mold or machine is used to attach the ribbon to the medal. The ribbon can be sewn, glued, or snap-fastened to the back of the medal.
7. **Quality Control and Packaging**: Each medal is inspected again before being packaged for distribution or display.
The result is a high-quality, custom gold-plated metal die-cast medal with a ribbon attached, suitable for various events, awards, or collections.
