Stamp / Die Marking
Stamp / die marking is a process that uses hardened steel dies to permanently imprint identification, part numbers, or other information onto metal surfaces. This method is valued for its durability and legibility in industrial applications.
Description
Overview of Stamp / Die Marking
Stamp / die marking is a mechanical process used to create permanent marks on metal parts and products. The process involves pressing a custom-designed die or stamp, typically made from hardened steel, into the surface of a workpiece. This creates an indentation that can include alphanumeric characters, logos, serial numbers, or other identifying marks.
Process Details
- Materials: Most commonly used on metals such as steel, aluminum, brass, and copper.
- Methods: Can be performed manually with hand stamps and hammers, or with powered presses for higher volume and consistency.
- Applications: Used for part identification, traceability, compliance marking, and branding.
Advantages of Stamp / Die Marking
- Permanence: Indented marks are highly resistant to wear, heat, and corrosion.
- Legibility: Produces clear, readable characters that remain visible throughout the product’s life.
- Versatility: Suitable for a range of part sizes and geometries.
Considerations
- Best suited for materials that can withstand deformation without cracking.
- May not be ideal for thin or brittle materials due to the force applied.
Common Industrial Uses
- Automotive part identification
- Metal fabrication traceability
- Tool and die marking
- Compliance and safety labeling
Summary
Stamp / die marking remains a reliable method for permanent part identification in industrial environments, offering durability and clarity for a wide range of metal products.
