Explore VT machining's Chemical Etching capability by metal. Photochemical etching uses a patterned resist and etchant to dissolve metal precisely, with no mechanical force, burrs or induced stress.
Chemical Etching by Metal
Process Capability
- Foil thickness 0.02–1.0 mm
- Minimum feature ≈ 0.8 × metal thickness
- Burr-free, stress-free edges
- Tooling-free: revise artwork digitally
Frequently Asked Questions
Can VT machining make custom parts to my drawing?
Yes. Chemical Etching is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
How clean are the edges produced by Chemical Etching on ?
Chemical etching removes the metal without mechanical force, so edges are completely burr-free and stress-free — no secondary deburring needed.
What is the finest feature you can etch in ?
As a guide, the minimum reliable feature size is roughly 0.8 × the metal thickness, so thinner foil yields finer apertures and detail — all produced burr-free and stress-free.
What is Chemical Etching and how is it done?
Chemical Etching refers to photochemical etching uses a patterned resist and etchant to dissolve metal precisely, with no mechanical force, burrs or induced stress. VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
