Aluminium and its alloys have always proved difficult to machine. Its ductility means it work-hardens when punched. Heat reflectivity makes it challenging to laser cut.
Similarly, with photo etching, the process is not straightforward. Aluminium releases heat energy during etching, resulting in a rough, granular edge.
100% tighter tolerances than the industry standard
To achieve smooth, accurate etch profiles, an innovative approach to etchant chemistry is required.
Precision Micro has developed a proprietary method for etching aluminium and its alloys, producing edge profiles comparable to those etched in stainless steel, to tolerances ±10% material thickness. That’s a 100% improvement on the industry standard for aluminium etching.
Aluminium’s light weight means greater fuel efficiency and lower carbon emissions. As the world’s only AS 9100- and IATF 16949-accredited photo etching company, Precision Micro specialises in photo etching aluminium components for automotive and aerospace.
- Photo etched helicopter air intake grilles are light weight and retain material properties during manufacture.
- 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.
- Compact, shaped heat exchanger plates can be photo etched with complex channel and pin arrays, reducing footprint and improving the thermal management of aircraft engines.
- Delicate, aluminium-clad Kapton ribbon tweeters can be etched with ultra-fine 0.025mm tracks, improving audio speaker frequency response.
- Aluminium car interior components, such as dials, dashboard fascias and instrument covers, are machined with high-definition logos, surface textures and profiles.
