Full Inspection
Optical & Roll Sorting
For automotive customers with special requirements, parts are 100% sorted before shipment to meet end-customer PPM targets.

Optical Sorting Machines
Reflected-light vision checks inner and outer diameter, eccentricity, missing material and surface defects. Recommended for customers with very low PPM requirements.

Roll Sorting Machines
By adjusting the gap as washers roll through, the machine separates parts by thickness and efficiently removes parts with poor flatness.

Multi-Line Capacity
Multiple sorting lines run in parallel, so 100% inspection does not slow down your delivery schedule.
Laboratory
Testing & Measuring Equipment
Spectrometer, CMM, tensile tester, Vickers and Rockwell hardness testers, salt-spray tester, height gauges, 2D vision measuring systems, digital micrometers and calipers cover every check from dimensions to material properties.








Process Control
Quality Control Flow
Our quality flow covers every stage — business acceptance, supplier assessment, incoming quality control, production, in-process inspection, outgoing quality control, storage and delivery — with corrective and preventive actions and customer satisfaction surveys closing the loop.
