temperatures up to 260°C. The first one has already been commissioned, and started up during 2017. The customer has already ordered a second line, for delivery in 2018.
Data integration NDC Technologies will debut several new measurement systems at Plast – which have data integration and connectivity down to the gauge level. The company will showcase its latest
FilmPro infrared gauge for the film, sheet and coating industries. It uses advanced optical techniques to measure a wide range of film and sheet properties with high precision. The modular device can measure the thickness of clear, voided, pigmented, cavitated, porous, translucent coloured and even black-tinted films. The measure- ment capability extends to single- or multi-layer products including thin, biaxially-orientated films, cast films and CPE stretch films. It can simultane- ously measure the individual thicknesses of up to six different layers in co-extruded films. At Plast, the gauge will be running on NDC’s
Mini-Trak O-Frame Scanner and
Pro.Net TDi Web Gauging System platform which includes NDC’s latest iView Pro Operator Work Station (OWS). At the same time, NDC’s new Low Energy X-Ray Sensor is aimed at thickness and basis weight measurements of lightweight extruded film and sheet products and offers good narrow streak resolution. A stable, precisely tuned power supply runs at or below 5keV providing high signal-to- noise characteristics and optimum measurement performance.
Offline inspection Sikora will showcase its new optical offline inspec- tion and analysing system called Purity Concept V – which combines a light table with automatic material control. The system analyses transparent and coloured plastic pellets. The material to be tested moves automatically through the system and contamina- tion such as black specks are visualised. The system is suitable for sample testing of produced material and for incoming goods inspection. Until now, sample testing of pellets has been carried out mainly by optically illuminating it on a light table, followed by manual inspection, says

Sikora. This relies on the examiner, and provides limited repeatability. Other limitations are: the size of the contaminants; and, their classification by size. Alternative systems feed the test material into a hopper and through a channel into the inspection area. This records images successively, and sorts out contaminated material. Due to the blending of the sorted out material, a clear allocation of the con- tamination to the graphic material as well as a follow-up inspection are impossible. Purity Concept V combines the advantages of a light table with automatic offline material control. The system moves the test material on a tray through the inspection area. Within seconds, it is inspected automatically by the colour camera – and contaminated material is marked directly on the sample tray by a beamer. By analysing the record- ed images, surface contamination of transparent and coloured material is automatically detected, visualised and evaluated. A clear allocation of the contamination and follow-up inspection are possible at any time, so the system helps quality control and process optimisation, says Sikora.
