Rofin: Real-Time Monitoring Of Perforation Quality

  • Monday, 02 March 2015 02:05

Until now it has been difficult to monitor and ensure that micro holes of consistent quality and diameter have been laser perforated. Typically these holes have diameters less than 120 microns while the packaging film moves with some 100-400 m/min.

Rofin offers true real-time monitoring of perforation hole diameter and percentage roundness with the VisionPerfoControl. Each laser perforation head will be fitted with a camera and the output of each camera is processed using pattern recognition software to record accurately the dimensions of the holes. This allows for validation of the micro perforation process and eliminates the possibility of incorrect set up (eg: focus error) from spoiling the output from the perforation system. Furthermore, the recorded data documents 100 percent perforation quality of the processed material.
