Applications of Etched Encoder Discs:
The Encoder Discs we etched:
Using photo chemical etching machining technique, Hysen manufactures custom metallic encoder discs with customer’s drawings. So that we can fabricate metal encoder discs with a wide variety of precise patterns, such as, capacitive encoder disc, optical encoder disc, reflective encoder disc, and magnetic encoder disc etc.
Benefits of Chemical Etching:
1. Cost-effective: no expensive molding tool required.
2. Fast sampling: sample within 2-3 days, not weeks.
3. High precision, micro and complex.
4. No additional cost for complexity.
5. Burrs and stress free, no sharp edge.
6. Mass production within days, not month.
7. Various material options: stainless steel, copper, brass, aluminum, alloys, titanium and so on.
8. No effect on material temper or magnetism.
