Quality Control

Fietz uses CAQ as QS Software. Through interfaces there is communication between SAP and the Measuring devices.

100% Quality Control is managed with equipment from Asentics and MRB.

Production assisted measurments and optically/tactile Analysis are generated with measuring devices from Mitutoyo.

Production assisted measurements and Analysis-mikroscopy is done with optical Equipment from Keyence.

Coordinate Measuring device from Wenzel LH65.
