Automated Inspection system for continuous webs

It is essential to find defects early in the manufacturing process to avoid waste and deliver high quality products. Increasing demands are being placed on manufacturers to boost efficiency and improve quality for defect-free product.

QVision Surface Inspection System is an optical quality inspection system that can be installed on a production line to detect surface defects in real time. The system enables manufacturers to reduce waste and downtime on their production lines and also to take corrective action to eliminate defective material before it is sent to customers.

QVision Web Inspection System offers a Wide Range of Benefits


Globally used In High Quality Manufacturing

Any material that is continuously manufactured in flat and wide form factor can be scanned for surface defects using a web inspection system. These systems are widely used on extrusion lines, sheet lines and coating lines that manufacture films and sheets of the highest quality.

  • Extruded Film Inspection
  • Speciality and Hygiene Film Inspection
  • Medical and Pharmaceutical Film Inspection
  • Metal Inspection
  • Paper Inspection
  • Solar Cell(PV) Backing Sheet Inspection
  • Laminates and Coated Substrate Inspection
  • Woven fabric (functional textiles) Inspection

We understand the need to evaluate the inspection system for a specific application. Therefore we have set up a demo system in our lab on a doctoring machine. Send us a sample roll to arrange a live demo and validate defect detection on the target substrate
