Features of Photochemical Etching:

1. High Accuracy: Achieve intricate and detailed digital designs that are not possible with traditional machining.
2. Flexibility:Easily accommodate design changes and modifications without the need for expensive tooling.
3. Material Efficiency: Save money by reducing waste and optimizing materials.
4. No Mechanical Stress:Maintain material integrity by avoiding mechanical deformation during etching.
5. Scalability:Efficiently scale from prototype to high-volume production.
6. Cost effective:Eliminates the need for expensive and time-consuming tooling
7. Cost efficient:Part complexity does not affect the production time
8. Rapid prototyping:Produce different designs at the same time without added effort.

How is the photochemical etching process?

FAQ:

Q1: What is photochemical etching?

A: A subtractive manufacturing process using UV light and etchants to dissolve unprotected metal areas, creating precise, complex parts without mechanical force or heat.

Q2: Why choose etching over laser/stamping?
A:

• No thermal distortion (vs. laser)

• No tooling wear (vs. stamping)

• Burr-free edges and micro-feature capability (down to 0.01mm details)

Q3: What metals can be etched?
A: Stainless steel (most common), brass, copper, aluminum, nickel alloys (Inconel, Hastelloy), titanium, and specialty metals like beryllium copper. Thickness range: 0.01–1.5mm.

Q4: What tolerances are achievable?
A:

• Standard: ±0.05mm

• High-precision: ±0.025mm (for critical clock components like escapement wheels)

Q5: How fast is prototyping?
A: Digital tooling enables:

• Prototypes: 24–48 hours

• Mass production: 3–7 days (for 10k+ units)
