Xinhaisen specializes in manufacturing custom metallic encoder discs using advanced photo chemical etching technology. We produce precision encoder discs with various pattern types including capacitive, optical, reflective, and magnetic encoder discs according to customer specifications.

The chemical etching method involves transferring component patterns onto light-sensitive resist material bonded to metal sheets. The unexposed photoresist portions are chemically stripped, exposing the underlying metal surface that is then dissolved using etchant chemicals.

1. Material Selection: Choose materials based on customer requirements
2. Material Cutting: Cut materials to required dimensions
3. Cleaning: Chemically clean the material surface
4. Printing: Apply photosensitive resist automatically on both material sides
5. Drying: Remove all water stains from the sheet
6. Exposure: Selectively remove photoresist to expose metal areas
7. Developing: Remove unexposed resist areas to leave exposed metal
8. Etching: Spray chemical etchant onto sheet to dissolve exposed metal
9. Stripping: Remove photoresist to reveal finished metal parts
10. Data Inspection: 100% quality inspection to meet customer specifications
11. Packing: Dust-free packaging for protection
