During the establishment of various raw material inspection systems, OCS was confronted with the increasing interest of polymer processing companies, to ensure the same excellent product quality for their customers as well as their subcontractors.

At first, a challenge was posed to develop a detection system for contamination, degradation and other impurities in transparent, opaque and coloured films during the production process.

The FSP600 is used for 100% surface control of films for running speeds up to 1000m/min and resolutions from 25 µm and allows the detection of every defect-type that often appears in film production and is feared by manufacturers, because it reduces the film quality enormously. The fast defect analysis with its representation of the inspection results during the production process is essential and applicable in all fields of film production and converting. With the aid of precision cameras, in conjunction with high performance heavy duty industrial equipment and devices, even the smallest defects in polymer products can be detected, located and analysed in detail. 

The used lighting technologies transmission or reflection mode consist of high frequent fluorescence lamps with a special designed focussing rod or high power blue/red/ white LED`s with chip on board technology (COB) and passive cooling management.

The Extended Hole Detection (EHD), a sophisticated type of software, enables the detection of holes in white or opaque films. The Representative Mosaic Container (RMC) displays the 100 most representative defect photos in one container.

The defects are classified according to customised defect classes such as flies, fibres, gels, black specks, scratches, etc. The images taken of these defects are stored for further analysis. The operator has the possibility to evaluate the defect image with 3-D analyser, moreover, the film test evaluation software enables the customer to reanalyze the defect information according to other specifications – this leads to whole roll quality analysis with the possibility of printing out customised quality protocols.
