What is Etching Finish?
A subtractive manufacturing process where:
1.Chemical solutions selectively dissolve metal surfaces
2.Creates permanent features without mechanical stress
3.Achieves precision unattainable with traditional machining
Key parameters:
Etching depth: 0.01-2mm
Minimum feature size: 0.05mm
Tolerance: ±0.01-0.05mm
Surface roughness: Ra 0.1-3.2μm
Etching Advantages
- Burr-free edges - Eliminates secondary deburring operations
- No heat distortion - Preserves material metallurgical properties
- Rapid prototyping - 24-48hr lead time for design verification
- Cost efficiency - 60-80% lower tooling cost vs stamping
Notes
- Material compatibility: Stainless steel, aluminum, copper, titanium
- Design requirements: 1:1 aspect ratio recommended
