Metal etching Complex, burr and stress-free components from any metal

What is metal etching?

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

At Precision Micro we use metal etching to offer 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.

The benefits of metal etching

Etching uses digital tooling, which means design changes can be carried out quickly. This process also means 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.

Full range of metal etching benefits:

  • 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
