Welcome to FLYcncpart's etching service! Through chemical or electrolytic processes, we create fine patterns for your parts, and our Shenzhen team ensures high precision and durability.
Description: Etching uses an acidic solution (such as FeCl₃ or HNO₃) or an electrolyte to selectively etch a surface, creating a pattern with a depth of 0.01-0.5mm. The process includes pattern making, etching (5-30 minutes), and cleaning. It is suitable for flat or slightly curved surfaces.
Applicable Materials: Metals (such as stainless steel, copper, aluminum), glass.
Visual Appearance: A recessed pattern or texture with high surface contrast.
Advantage
High-Precision Patterning: Line widths up to 0.05mm are suitable for complex designs.
Durable: Etched patterns resist wear and provide permanent marking.
Stress-Free: The chemical process does not affect tolerances.
Multi-Material Compatibility: Suitable for metal and glass, offering high flexibility.
Cost-Effective: Suitable for medium-volume production with low platemaking costs.
Decorative Features: Unique textures or logos can be created.
Precautions
Acid Management: Use FeCl₃ or HNO₃, controlling the concentration (10-30%); test the etching rate.
Time Control: Avoid overetching for 5-30 minutes, and monitor the etching depth.
Surface Preparation: Keep the surface clean and free of oil and dirt that could affect pattern clarity.
Design Considerations: Plan the etching area to avoid critical structures.
Quality Standards: Comply with ISO 10110, checking for etching depth and uniformity.
Safety Measures: Wear protective clothing and gloves when handling acid waste.
