Chemical Etching Overview

Chemical etching, also known as photochemical machining, uses acidic solutions to selectively remove material from metal sheets. The process involves coating the metal with a photoresist, exposing it to a pattern, developing, and then etching. DRAGON ETCHING's state-of-the-art facilities and rigorous quality control ensure each component meets the highest standards of accuracy and reliability. From prototype development to large-scale production, the company works closely with clients to transform complex designs into precise, functional metal parts.

Etching Stainless Steel

Stainless steel is valued for its corrosion resistance and strength. Etching stainless steel requires careful control of etchant composition and temperature. Common etchants include ferric chloride and nitric acid mixtures. Key considerations include grain structure and passivation layer removal. Applications include medical devices, automotive components, and decorative panels. DRAGON ETCHING's expertise ensures burr-free edges and tight tolerances.

Process Considerations

• Surface preparation: cleaning and degreasing.

• Photoresist application and exposure.

• Etching parameters: time, temperature, agitation.

• Stripping and inspection.

Etching Copper

Copper is widely used in electronics due to its electrical conductivity. Etching copper is relatively fast, but requires precise control to avoid undercutting. Ferric chloride is the typical etchant. Applications include printed circuit boards, heat sinks, and decorative items. DRAGON ETCHING's advanced facilities enable high-volume production with consistent quality.

Advantages of Chemical Etching for Copper

• No burrs or stress.

• Fine detail resolution.

• Cost-effective for complex designs.

Etching Aluminum

Aluminum is lightweight and corrosion-resistant, but its oxide layer can complicate etching. Alkaline or acidic etchants may be used, with careful handling to avoid pitting. Applications include aerospace components, nameplates, and filtration screens. DRAGON ETCHING's rigorous quality control ensures repeatable results.

Challenges and Solutions

• Oxide removal: pre-etching with caustic soda.

• Temperature control to prevent excessive reaction.

• Post-etching passivation for corrosion resistance.
