Your AS 9100-accredited photo etching partner
Aerospace design for manufacture is driven by safety, reliability and cost. Environmental sustainability is also a key consideration.
As an AS 9100-accredited company, Precision Micro is one of the few photo etching suppliers approved to deliver safe, reliable components to the sector. We are also pioneering new technologies which will improve the efficiency of next generation aircraft engines and electro-thermal ice protection systems.
Photo etching aerospace materials
Photo etching is suitable for all metals, including aerospace-grade aluminium and titanium. These metals are challenging to machine using conventional sheet metalworking and often require costly rework to remove undesirable recast layers, stresses and burrs.
As a non-contact, non-heat inducing machining process, photo etching produces stress, burr-and distortion-free components. This makes it ideal for aerospace parts which require subsequent stacking and bonding, or actuation with little to no wear.
Precision Micro is the world’s leading supplier of ultra-thin chemically-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 and in lengths up to 1500mm. Competing technologies would be unable to offer the repeatability and accuracy required over such a large area.
A pocket-sized surveillance drone measuring less than 1 ounce operates using miniaturised motor laminations photo etched to ±0.020mm accuracy. Laminations are bonded using the photo-resist protecting the metal surface during etching, improving performance versus punched, riveted and welded laminations.
Weight and space saving solutions
Complex channels and geometries can be photo etched onto individual heat exchanger plates, maximising thermal efficiency. Unlike single-point machining processes, we etch intricate channels simultaneously, meaning costs do no increase with part complexity.
Lightweight aluminium heater plates stacked and used in aircraft dehumidifiers require multiple designs which can be set up cost-effectively with photo etching and include smooth channels to improve air flow.
Quality, traceability and compliance
Precision Micro is one of few photo etching companies accredited to AS 9100, the quality management system standard required to supply the world’s leading aerospace, space and defence businesses.
We analyse our materials using X-ray fluorescence to ensure elemental compositions conform to material certificates.
We are committed to maintaining full legal compliance with global export and import regulations, including International Traffic in Arms Regulations (ITAR).
