Precision tubes are produced in a multi-step cold drawing process. they are primarily used in the automotive sector for the production of hydraulic cylinders, airbags, and drive shafts. Medical technology uses particularly small precision tubes for stents, etc.
Diligent material testing is crucial due to the high quality requirements for precision tubes:

DEFECTOMAT: The DEFECTOMAT test systems are used for testing  precision tubes for point and transverse defects in the material surface.

DEFECTOMINI: The DEFECTOMINI was developed for precision tubes with particularly small material diameters. It can detect even the smallest surface defects.

CIRCOGRAPH: The CIRCOGRAPH product family was developed for the testing of longitudinal surface defects. The system are contactless and uses rotating test heads.

MAGNATEST D-HZP: The MAGNATEST D-HZP test system can be used for performing material identification checking and hardness checking on the test material. The system uses the magnetic-inductive method for this purpose.
