40 Extrusion International 2/2019 MEASURING TECHNOLOGY Inline Measurement of the Inner Cross- Section Geometry of Extruded Products Measurement of inner cross-section geometrywithProfilControl 7 ICSM: New inline systemfromPixargus is thefirst to alsomeasure the rateof recycledmaterial ProfilControl 7 ICSMfromPixargus keeps aneyeonmaximizing the rateof recycled material in cut plastic profiles produced by co-extrusion. The inline inspection system illuminates the complete internal geometryof theprofiles andmeasures the coating layers andwall thicknesses ina continuous process. In thisway it is possible tomaximize theuseof recycled plastics inprofile cores. As a result, productionbecomesmore cost-efficient and theproductsmore sustainable Today’s high-grade recycled plastics are suitable materials for use in the cores of high-tech profiles. While be- ing virtually just as robust and long- lasting as virgin plastics, recycled plastics are more favourable in terms Today’s high-grade recycled plastics are suitable materials for use in the cores of high-tech profiles.

This is because recycled plastics can be produced with less energy – re- ducing the CO 2 footprint – and they are relatively low-priced. ProfilControl 7 ICSM (PC7 ICSM) is the first system able to measure the rate of recycled plastics in extrusion processes. Highly specialized measuring algorithms: up to the limits of the feasible In order to get a grip on the inside geometry of profiles, Pixargus has merged special measuring algorithms into an entirely new measuring con- cept. Highly specialized algorithms measure not only the coating layers and wall thicknesses, but also the rate of recycled material used. “It has now become possible to increase the rate of recycled material in profile production up to the ultimate limit because the rate is being continuously checked as the profile leaves the cutter,” explains Michael Frohn, Sales Manager at Pixar- gus. The ICSM system is already being used for the inspection of cut window andmetal profiles. It is also the solution of choice for the inspectionof extruded hoses and tubes, where it can be used in place of conventional ultrasonic measuring systems.
