Metal etchingComplex, burr and stress-free components from any metal

What is metal etching?

Metal etching, also known as photo etching, chemical etching or chemical milling, is a subtractive metal machining process which uses etchant chemistry to produce complex, highly accurate metal components.

Metal etching offers a fast, economical alternative to stamping, punching, laser and water jet cutting when machining feature dense, tight tolerance components from almost any thin gauge metal to 1.5mm thick.

Metal etching benefits

The tooling for metal etching is digital, meaning design changes can be carried out quickly and design optimisation is risk-free without financial penalty.

No mechanical force or heat is used during the metal etching process, ensuring material properties are unaltered and components are free from stresses and burrs.

As component features are machined simultaneously almost limitless part complexity is achievable, with accuracy to ±0.025mm.

Benefits at a glance:

  • Unlimited complexity – you only pay for the first hole
  • No expensive hard tooling required
  • Low-cost design iterations – fast
  • Burr and stress-free – metal properties unaffected
  • Lead-times in days, not months
  • Virtually any metal
  • Accuracy to ±0.025mm
