Professional Engineering & Quality Control
Electrical terminals are small components, but their dimensional requirements can be highly demanding. A small deviation in contact width, insertion height, hole position, bending angle or terminal pitch can affect assembly performance or electrical contact reliability.
Our engineering approach therefore focuses on the complete production chain:
Material → Tooling → Stamping → Forming → Surface Treatment → Inspection → Assembly
Critical Quality Points
- Material composition
- Material thickness
- Terminal pitch
- Hole position
- Contact width
- Bending angle
- Flatness
- Burr height
- Surface condition
- Plating coverage
- Dimensional repeatability
For high-volume electrical terminal production, progressive tooling can integrate piercing, blanking, bending and forming operations into a continuous process, improving production efficiency and consistency.
Cooperation Cases

- Optional plating
Professional Marketing Description
Precision Where Electrical Performance Begins
An electrical terminal may be a small component, but it plays a critical role in the reliability of the entire electrical connection. The quality of the terminal directly influences contact resistance, insertion force, connection stability, current transmission and long-term reliability.
That is why our approach goes beyond simply stamping brass into shape. We engineer the complete manufacturing process around the terminal's functional requirements. From selecting the appropriate copper alloy to designing the progressive die, controlling forming operations and optimizing the final surface treatment, every stage is considered to achieve consistent production performance.
