Rofin has unveiled the VisionPerfoControl, a device for real-time monitoring of perforation quality.
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 is the first supplier to offer 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 from spoiling the output from the perforation system.
Furthermore, the recorded data documents 100 per cent perforation quality of the processed material.
