Testing system "HeiDetect (fully automatic x-ray testing)"

Portfolio: Measurement and Test Engineering
Industries: Automotive


HEITEC subsidiary Erhardt + Abt develops and constructs the world’s fastest fully automatic wheel testing system.


Implementation HeiDetect Wheel Robot is a fully automatic wheel testing system that uses the ISAR image evaluation software and the XEye detector, developed by the Fraunhofer Development Center for X-ray Technology (EZRT), to produce an evaluation with stable image quality and almost no false negatives.

Powerful image processing enables casting flaws like shrink holes, pores, cavities, and foreign objects to be identified and classified. Defects making up as little as three percent of the irradiated wall thickness can be identified. Large oxides can be detected from just one percent of the wall thickness.

The options of automatic wheel recognition and incorporating bar codes offer additional advantages. This makes it possible to determine wheel orientation and follow up on the test results.

The HeiDetect Wheel Robot wheel testing system meets the latest wheel specification requirements and can accommodate wheel sizes of 13 to 24 inches. The ISAR evaluation software offers an ergonomic, Windows-based user interface that allows testing parameters to be set in accordance with customer requirements.

Important data can be transmitted to an existing data acquisition or PPC system. Specially prepared test results are transmitted to Production in real time, allowing trends to be monitored and product quality to be continuously optimized to keep waste to a minimum.

Customer benefits

  • Evaluation with no false negatives
  • Stable image quality
  • Shorter testing time for each wheel
