GDO BV is a Dutch-based machine builder and supplier

of custom-made vision technology solutions. We offer high-tech

technology to producers in the medical technical industry.

This project is sponsored by a contribute from the European foundation

for regional development under OP-Zuid

Stent manufacturers throughout the world come across the same dilemma every day: the manual stent inspection is not 100% reliable nor 100% objective. Result: the price paid for uncertainty is too high.

GDO was asked to think out a solution. Our engineers took the challenge and research was com-menced. Professionals from different backgrounds exchanged their experiences and opinions at the GDO Stent-Nuremberg conference in 2007. This basis was used to define the scope for the ideal automatic stent inspection. Three years of research and development, testing, measuring and close cooperation with stent manufacturers followed.

The result may be seen! The Nuremberg Stent Inspection – 7 or just NSI-7. A 100% stent inspec-tion system, 100% reliable and 100% objective. Flexibility is increased and costs are reduced.

Inspired by stent manufacturers, made by GDO. The ultimate stent inspection.

Machine compositionThe NSI-7 consists of three main modules:• Geometry measurement of the stent structure• 3D surface inspection of both the inner and outer surface• Contactless wall thickness measurement

Software

• Uniquely developed software for geometry measuring, 3D surface and thickness inspection

• Every inspection uses state of the art computers, to make sure that there is

no interference

• Every software module consists of:

• A measurement and assessment level for the inspection

• A preferences level to adjust the parameters

• Process analysis

• Calibration of the various measuring positions

• Linking to your ERP system

• Measuring tools

• Data logging to track and trace the stents

If you have a special wish, please let us know.

The NSI-7 is modular built, configurable for the customer and custom made delivered. No matter of the chosen configuration, complete objectivity and reliability are guaranteed at all times. The special developed software overtakes the decision making about stent quality, human errors will be reduced to zero and external disturbances won’t be of influence anymore.

The NSI-7 expands your flexibility. The machine can be equipped to any needs with different amounts of mandrels, or in other words, stents. The inspection is carried out automatically and completely independent of human interference at a speed of 2 stents per minute. Working 24/7 is no challenge for the NSI-7.

Throughout the development process, ease of use has always been one of the key requirements, which lead to a simple machine operation for both the operator and the quality manager.

The NSI-7 is a giant step forward for manufacturers in the medical industry. The European Union, Province Limburg and OP Zuid acknowledged the innovative character of this development and participated.

The advantages of the NSI-7 • Completely reliable • 100% automatic • Huge cost savings • Process analysis • Totally objective • Availability 24/7

Contactless wall thickness measurement

The technology enabling this inspection is a 3D spot measurement.

• Measurement accuracy: 0,00004 mm

• Process reliable accuracy: 0,0005 mm

• Contactless

• Chromatic principle

• Number of measurement spots is determined by the quality manager

• Assessment based on parameters fixed by the quality manager

Geometry measurement of the stent structure

The technology enabling this inspection is the linescan camera well known to GDO.

• Measurement accuracy: 0,001 mm

• Process reliable accuracy: 0,005 mm

• 360 degrees of the stent surface

• Pattern matching, every stent is compared to the perfect stent

• Strut width, damages, deformations and geometry defects

• Assessment based on parameters fixed by the quality manager

3D surface inspection of both the inside and outside surface

The technology enabling this inspection is a 3D line scan.

• Measurement accuracy: 0,00015 mm x 0,005 mm x 0,005 mm (ZXY)

• Process reliable accuracy: 0,0005 mm x 0,0001 mm² (Z-XY)

• 360 degrees of the outer surface

• 360 degrees of the inner surface

• Conversion to a 3D view

• Defect definition is shown in a 3D image, with defect depth.

• Detects pits, scratches, micro cracks, dents, foreign matter and cutting failures

• Assessment based on parameters fixed by the quality manager
