Etching Services

Processing Overview

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.

• 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.

• 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.
