Etching customization process

Step 1: Phototool Design / CAD Design

Our skilled engineers design precise phototools or utilize computer-aided design (CAD) to create digital blueprints for the desired metal component.

Step 2: Metal Selection & Prep

The appropriate metal material is selected based on project requirements, ensuring compatibility and optimal performance. The metal surface is meticulously cleaned and prepared for the photoresist coating.

Step 3: Photoresist Coating

A photoresist material is applied to the metal surface, forming a protective layer that will define the etching pattern.

Step 4: UV Exposure

The metal substrate is exposed to ultraviolet (UV) light through the phototool, which transfers the desired pattern onto the photoresist-coated surface.

Step 5: Development

The photoresist-coated metal is developed, removing the unexposed areas and revealing the etching pattern.

Step 6: Chemical Etching

The metal substrate undergoes chemical etching, where it is immersed in an etchant solution that selectively removes the exposed areas, leaving behind the desired etched pattern.

Step 7: Photoresist Stripping

The remaining photoresist is stripped from the etched metal surface, revealing the clean and precise etched features.

Step 8: Final Inspection

Each etched metal component undergoes a rigorous inspection process to ensure quality and accuracy before being released for delivery.
