In the case of cast aluminum components, blowholes on functional surfaces can be visible after machining. As a result, the part is scrap or the quality for subsequent processes is not achieved and rework is necessary. To ensure that only high-quality products are delivered, Alpine Metal Tech offers a fully automatic optical inspection cell for 100% control during production.

Workpieces are manufactured with different surface finishes, where also different tolerances are needed; e.g. liquid sealing area (rough surface), solid sealing area (smooth surface), water connections (very fine surface), complex manufactured functional surfaces. The optical test system checks these surfaces for damage, blowholes, ...
