Tire inspection machine
INTACT®
Steinbichler Optotechnik
The shearography tire test systems INTACT from Steinbichler Optotechnik have been developed for the non-destructive testing of new tires in R&D and quality control, as well as for the inspection of tire carcasses in the retreading industry. The technical basis of the systems is the TV shearography system.
During the test cycle, a low pressure (e.g., 50 mbar pressure difference) is generated in the vacuum chamber, thereby inducing deformations which are caused by the expansion of air pockets occuring in faulty areas in a tire carcass. With the TV shearography technique - a holographic measurement method which reliably detects material deformations in the range of microns - faulty areas can be localized clearly and reproducably.
The high flexibility of the tire testers allows testing of tires with a wide range of diameters and sizes without any system changes. With an optional tilting axis on the measuring head, the inspection of the bead and sidewall of the tire is also possible.
Owing to the fact that 95 % of the faults in a tire can be detected with the INTACT systems, high safety standards are achieved. Especially for the retreading business the systems offer a high economic potential because useless carcasses can already be rejected before further processing takes place. In comparison to ultrasound test system, the decisive advantage lies in the fact that the tires do not need to be put into a water tank.
The INTACT systems by Steinbichler Optotechnik have successfully proven their functionality in the worldwide car-, truck-, and aircraft industries, as well as in the Formula 1 racing tire business.
