Metal etching is a subtractive sheet metal machining process which uses etchant chemistry to produce complex, highly accurate metal components.
At Precision Micro we offer a market-leading metal etching service that can manufacture feature dense, high precision components faster and more economically than traditional stamping, laser and water jet cutting.
→ Get in touchEtching 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:
The metal etching process works by ‘printing’ a component design onto photoresist which is laminated onto metal. The areas of photoresist which have not been printed are removed, exposing the metal, which is subsequently etched away.
Almost any metal can be etched. Select a material below to get started:
We also work with customer supplied material. Please contact us for more information.
Precision Micro has pioneered photo etching for over half a century, setting the standard for accuracy and repeatability. Our 10-strong technical team includes PhD and degree-qualified engineers, metallurgists and chemists, pioneers of advanced production techniques for components and materials once thought too difficult —even impossible —to photo etch.
We are the only photo etching company accredited to AS 9100, IATF 16949, ISO 9001 and ISO 14001, so you can rely on the stability and capability of our processes. Our robust quality systems are underpinned by a continuous quality improvement programme which ensures repeatability levels approaching Six Sigma standards.
At 44,000 sq ft, our state-of-the-art photo etching plant offers the largest sheet etching capacity in Europe. Key technologies include a class 10,000 clean room, cut-sheet lamination for blemish-free components, laser direct imaging for finer components, product-specific manufacturing cells and a best-in-class in-house metrology facility.
We specialise in etching proprietary super-alloys which exhibit excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation.
We stock the widest range of standard and specialist material types and grades in thicknesses from 0.010mm-1.5mm and in sheet sizes to 600mm x 1500mm.
We have sales offices and partners in locations that enable us to respond quickly to customer requirements. Our sales engineering team has first-hand knowledge of photo etching and can advise on design parameters which lower manufacturing costs.
We offer a number of additional in-house services which can be combined with photo etching to produce components with greater accuracy, unique characteristics and improved functionality, reducing customers’ supplier base and time-to-market.
Precision Micro is well-invested, enabling us to deliver the levels of product quality, productivity and competitiveness expected by major international companies.
