Metal stamping is a manufacturing process that uses a stamping press and dies to transform flat sheet metal into various complex shapes. This process involves applying pressure to a metal sheet, forcing it into a die to create a specific shape or cut. It's commonly used to produce parts for a wide range of products, from small electronic components to large automotive parts.
Common Metal Stamping Techniques
| Technique | Description | Applications |
| Blanking | Cutting a piece out of sheet metal to create a blank for further processing. | Used as a precursor to other stamping operations. |
| Punching | Creating holes or cutouts in sheet metal using a punch tool. | Common in progressive or transfer stamping; can also be a standalone operation. |
| Coining | Compressing metal between a punch and die to create detailed features or patterns. | Used for adding logos or trademarks to components. |
| Embossing | Raising an area on the surface of sheet metal using a machine or die set. | Applied in various industries, including automotive and decorative items. |
| Deep Drawing | Shaping sheet metal into three-dimensional forms, typically cylindrical components like cups. | Common in manufacturing automotive parts, kitchen sinks, and metal containers. |
