Extrusion International 5-2021

43 Extrusion International 5/2021 SIKORAAG www.sikora.net SIKORA A6-6110 SIKORA will present innovative mea- suring and control technologies for the tube, hose and pipe industry as well as online and of fl ine systems for the inspection, sorting and analysis of plastic pellets at this years Fakuma. In the area of online inspection and sorting of plastic pellets SIKORA presents the PURITY SCANNER AD- VANCED. The system combines in a unique way an X-ray with up to three optical cameras. Thus, even the small- est metal inclusions in the raw mate- rial from a size down to 50 μ m can be detected. In addition, the optical cam- eras detect black specks and burns on the pellet surface. Defective pellets are separated immediately after de- tection by means of compressed air. At the Fakuma, SIKORA offers cus- tomers free live material tests with the PURITY CONCEPT V. The system is typically used for of fl ine laboratory testing and random sample inspec- tion. Interested customers are invited to bring small pellet samples (approx. 100 g) to the SIKORA booth to have them tested. The automated light ta- ble automatically inspects the test ma- terial placed on a sample tray within a few seconds by using a color camera and evaluates the image recordings. The system detects black specks and color deviations down to a size of 50 μ m and highlights contamination in color on the monitor image and in parallel via a projector on the sample carrier. A clear assignment of the con- tamination and a follow-up control are thus possible at any time. For a 100 % quality control during pipe extrusion SIKORA presents the CENTERWAVE 6000, which is basedon millimeter wave technology. The de- vice precisely measures the diameter, ovality, wall thickness, inner pro fi le as well as sagging of the pipe. The mea- suring method does not require any coupling media or calibration and is free from in fl uences such as tempera- ture or the plastic material. Another highlight at the SIKORA booth is the X-RAY 6000 PRO. The X- ray based system measures the wall thickness, eccentricity, inner and out- er diameter and ovality of tubes and hoses from 0.65 mm diameter. The thickness of up to three different ma- terial layers is measured. Automatic control of the line speed or extruder rpm ensures maximum productivity. SIKORA’s presentation at Fakuma is rounded off by reliable diameter mea- suring systems of the LASER Series 2000 and 6000. The 2-axis or 3-axis gauge heads are predestined for diameter measurement of transparent as well as non-transparent tubes and hoses.
