As an AS 9100 accredited photochemical etching company, Precision Micro is one of the few chemical etching suppliers approved to deliver safe, reliable components to the aerospace, defence and space sectors.
Chemical etching aerospace materials
Our chemical etching service is suitable for metals that are often challenging to profile using conventional sheet metalworking.
Etching produces 100% stress, burr and distortion-free components. This makes it ideal for aerospace parts that require subsequent stacking and bonding, or actuation with little to no wear.
Specialists in ice protection systems
Precision Micro is the world’s leading supplier of ultra-thin photo-etched resistive heating elements used in electro-thermal ice protection systems.
We photo-etch defect-free elements from copper and nickel alloys to extremely tight resistance tolerances in lengths up to 1500mm. Competing technologies would be unable to offer the repeatability and accuracy required over such a large area.
Pioneering compact heat exchanger plate design and manufacture
We manufacture compact, lightweight heat exchanger plates for use in aircraft dehumidifiers and engines.
Unlike single-point machining processes, we machine plates with intricate channels simultaneously, maximising thermal efficiency and reducing cost.
Miniaturised UAV components
Surveillance drones benefit from our miniaturised motor laminations, etched to ±0.020mm accuracy.
We can bond electrical steel laminations using the photoresist protecting the metal surface during etching, often improving performance versus punched, riveted and welded laminations.
Sundry and specialist photo-etched aerospace components
The versatile nature of chemical etching makes is suitable for a wide range of aerospace components.
Precision parts we produce for the aerospace sector include:
- Precision metal shims and washers
- Flat springs
- EMI/RFI shielding cans and components
- Air intake grilles and filtration meshes
- Decorative components for instrument panels and aircraft cabins
Quality, traceability and compliance
Precision Micro is one of the few chemical etching companies accredited to AS 9100, the quality management system required to supply the world’s leading aerospace, space and defence companies.
We analyse our aerospace materials using X-ray fluorescence to ensure elemental composition conforms to material certificates.
We are committed to maintaining full legal compliance with global export and import regulations, including International Traffic in Arms Regulations (ITAR).
