Quality Checker

Precise inspection of glass quality and dimensions

The Quality Checker takes over the final inspection within your glass production and verifies optical glass quality and glass dimensions. At the same time, the machine documents all quality relevant results. This efficient final quality control can be integrated within the tempered glass production as well as at the end of the insulated glass production line. This allows you to further reduce your claim costs, secure your in time delivery and to be always prepared for the worst case scenario.

Machine summary:

The individual adaptable Quality Checker is positioned at the end of your production line, directly behind an IG press or tempering furnace. Once installed it guarantees the glass quality you desire. The scanner measures glass width and height, as well as hole positions and diameters, or the exact position of the spacers and Georgian bars – no matter if you are working at normal standards or attempting to meet a higher quality.

The speed and illumination of the device adapts automatically to the speed of your production line. Thanks to the patented telecentric illumination, the various inspection tasks can be combined perfectly. And all without production time delay.

Your benefits:

  • Reduced complaint ratios
  • Ensure the required delivery quality
  • Decreased cycle time in glass production
  • Establish your own level of quality
  • Documentation of all quality relevant results
  • Statistical quality analysis
  • Improved overall quality within production
  • Quick pay back
