Precision Micro has developed an improved chemical etching process for aluminium that delivers better edge uniformity, tighter tolerances and high repeatability for complex aerospace components. The technique avoids mechanical stress, burrs and heat-affected zones while enabling intricate geometries such as heat-exchanger plates, helicopter air-intake grilles and UAV parts. The innovation addresses aluminium’s reactivity challenges and supports the strict quality demands of the AS9100 standard amid growing aircraft demand forecast by Airbus.
