Although inspectors are able to recognise a high proportion of surface defects reliably and quickly, visual evaluation is often subjective and depends heavily on several factors, including tyredness, lack of concentration and varying light conditions. The aim of surface inspection is to achieve an objective, reproducible evaluation of surface deviations in order to quickly and reliably make decisions with respect to component tolerances.
Flawless surfaces with a uniform appearance are equally important in the aerospace industry. World-class inspection services are therefore needed, whereby small bumps and dents caused during fuselage mounting are only recognisable after the painting process and often lead to complaints during customer acceptance tests. Furthermore, flush rivet heads and the smallest possible rivet indentations in the outer skin of the aircraft are technically and aesthetically critical. In addition to versatile applications on the outer skin of an aircraft, the interior also offers a variety of potential applications including the inspection of flaps on hand luggage compartments, armrests and wall coverings.
Sophisticated smartphones, tablets and notebooks not only stand out as versatile, technical equipment but also due to their high quality housings and finish. In order to reduce weight and materials, the wall thickness is often reduced to a minimum. This could cause slight sink marks and other discontinuities on the surface, which become visible under certain lighting conditions.
An increasing number of sophisticated household appliances are now designed and equipped with high quality surfaces. For example, freestanding refrigerators are often a decorative eye-catcher in a modern kitchen. Washing machines also match modern interior designs with their flawless, attractive appearance. This is why an immaculate surface for domestic devices is becoming increasingly important.
