The thinner plates and foils become during rolling, the higher the likelihood that pinholes will arise. Pinholes are the reason for broken strips, particularly in the case of foils. With the use of unique global patented Camera-Cluster-Technology you are able to detect the smallest of perforations during the production.
Up to a strip speed of 1,400 m/min and almost unlimited strip width, the IMS pinhole detector achieves a never experienced detection rate and detects pinholes with a size from 5µm upwards.
Light emitted from the backlight unit passes through a pinhole is detected by a CMOS photosensor and further processed. An intelligent strip edge tracking combined with a respective light source control provides very small edge masking areas (blind zones). As a result, almost 100% of your strip can be inspected for pinholes.
SECURE THE ADVANTAGE OVER YOUR COMPETITORS!
100% be inspected for pinholes
»The Pinhole detector of IMS has a very low edge fading of three millimeters. Thus, the coil is examined to almost 100 percent to pinholes.«
