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.
