Main features:

  • Recognizes defect sizes from 0,02 mm upwards
  • Inspection also under deformation (rip/tear recognition)
  • Complex geometries
  • Multiple inspections in one device
Function:

This system is designed for complex seals which have several inspection criteria.

The seals are carried in a pallet and can be examined from different views in high resolution, including: from above, from underneath, from the front or from the inside of the interior. For example with rotary shaft seals, not only is the seal's edge checked through deformation for edge breakage smaller than 0,02mm, but the surface of both sides of the seal (also for rips/tears), the spring seat, the dust protection lip and the exterior for all well-known surface defects are also simultaneously inspected.


Technical Details:

Our modern inspection systems have proven to be very successful in the quality control of seals made from rubber, ceramic, or other similar materials.
Surface and Geometric Inspections for:

  • Rotary Shaft Seals (Oil Seals)
  • Diaphragms, V-Seals
  • Ceramic Seals
  • Flat Gaskets
  • Plugs, Rubber-to-Metal Bonded Parts

These systems use state-of-the-art optical and contact-free inspection engineering techniques.  They are constructed with the newest algorithms in image processing, which guarantees a 100 percent inspection result along with user-friendly handling.

The image processing software contains progressive analytical processes for surface control, as well as an expert-system with fully-developed algorithms designed for artificial intelligence.  This not only ensures the most up-to-date software techniques, but also an outstanding inspection result.  The pattern recognition feature enables the system to assign different margins of error (tolerances) to specific defects, which also decreases the often high rate of pseudo-rejects.
