What technologies are involved in precision sheet metal processing?

2025-07-31

Precision sheet metal fabrication involves a variety of advanced technologies, primarily including the following core processes:

1. Laser Processing Technology

Fiber laser welding: Suitable for high-precision welds, but requires attention to material dependence and deformation control.
Tube laser processing: Reduces labor time and costs, enabling the processing of complex shapes.
5kW laser oscillator: Supports high-speed cutting of non-ferrous metals such as aluminum and copper.

2. Forming Technology

CNC bending: Uses a press machine and molds to precisely form parts, enhancing structural strength.
Stretch bending/cold bending/hot bending: Suitable for forming complex curved surfaces on hyperbolic sheet metal (such as aluminum and stainless steel).
Stamping and drawing: Used for mass production of high-precision parts (such as automotive panels).

3. Joining Technology

TIG/MAG welding: Suitable for welding three-dimensional objects from thin to thick sheets.
Robotic welding: Improves efficiency and consistency, and is used for the assembly of complex structures.
Riveting: Uses fasteners such as rivets and nuts to connect.

4. Surface Treatment

Includes processes such as powder coating, electroplating, and brushing to enhance appearance and corrosion resistance.

Hypercurved sheet metal requires special treatment to prevent surface dents or scratches.

5. Digital Assisted Technologies

3D modeling software (such as SolidWorks and Rhino): Used for nesting and CNC programming.
CNC cutting (laser/plasma): Enables high-precision cutting.

6. Special Processes

Laminating Technology: Patented mechanism allows for quick installation of laminating rollers, improving efficiency.
Copper Busbar Punching: Enhances tapping strength and is suitable for sheet metal thicknesses under 5mm.

This combination of technologies meets the diverse needs of precision sheet metal parts in the electronics, automotive, and construction industries.
