Extrusion International 4-2019

PREVIEW 58 Extrusion International 4/2019 At K 2019, SIKORA presents a broad portfolio of innovative systems for quality control and process optimization for hose and tube, sheets as well as plastics industries. Visitors have the possibility to bring along plastic pellets for a live and on the spot inspection and analysis with the laboratory testing sys- tem PURITY CONCEPT V. In the “Innovation Corner”, visitors are cordially invited to contribute their ideas regarding mea- suring technology for hose and tube as well as plastics appli- cations. The appearance of the company from Bremen at K promises pure innovation. World premiere of the CENTERWAVE 6000 for dimension measurement of hose and tubes of up to 1,600 mm diame- ter: With theworld premiere of the CENTERWAVE 6000/1600, SIKORApresents ameasuring systemof a newdimension. The system was developed especially for quality control of plastic tubes and pipes during extrusion. Due to its design, the sys- tem offers a precise measurement of tubes with a diameter from630 to 1,600mm. The CENTERWAVE 6000 is based on in- novative millimeter wave technology and measures continu- ously and completely over 360 degrees of the circumference of the pipe the wall thickness, the diameter, the ovality, the inner profile and the sagging. “The CENTERWAVE 6000 does not only impress because of its dimensions,” says Christian Schalich, Head of Sales Business Unit Hose & Tube at SIKORA, “but foremost due to its benefits resulting from the technolo- gy for the extrusion process.” Nominal dimensions are quickly reached, start-up scrap is avoided, the highest quality guar- anteed and processes are optimally controlled. Furthermore, the system does not require any coupling media, it measures precisely and independently to external influences, such as temperature or plastics material, and does not require calibra- Numerous Premieres at the Booth tion. “Furthermore, the device determines automatically the exact refractive index”, says Schalich. It defines the intensity and how fast radiation travels through the material and is therefore decisive for the measuring accuracy. Manual input of modifications of the production conditions is not required. “The operator benefits from a system that, integrated in the line, delivers reliable and reproducible measurement values directly after start-up”, adds Schalich. Thickness measurement in the sheet extrusion with the PLANOWAVE 6000: SIKORA’s PLANOWAVE 6000 is a non- contact measuring system that is used for non-destructive thickness measurement during the extrusion of plastic sheets. The system measures sheets made from engineering plastics like POM and high-performance plastics like PEEK. The PLA- NOWAVE 6000 is also suitable for the measurement of trans- parent and synthetic plastics like PMMA and PVC-FOAM as well as for glass. Themeasuringmethod is basedonmillimeter wave technology for thehighestmeasuringaccuracy indepen- dent of material and temperature of the sheets. A calibration on the material is also not needed. The PLANOWAVE 6000 can be integrated directly into the production line at the hot or cold position. The visualization of the measuring values is done in real time at the monitor of the processor system ECO- CONTROL 6000. Besides a numerical display of the measuring values at any number of measuring points over the width of the sheet, the operator also receives a graphical display with extensive trend and statistical functions. Premiere: Optical laboratory testing system PURITY CON- CEPTVwith color detection: With the Kpremiere of the PURI- TY CONCEPT V, SIKORA presents an optical laboratory testing system for plastic material. The system is an automated light table where plastic pellets, placed onto a sample tray, are be- ing moved through the inspection area. Within seconds, the material is inspected by a color camera. A projector optically marks all contaminated pellets directly on the sample tray. By evaluating the images, contamination, like black specks, from The CENTERWAVE 6000 measures big pipes by millimeter wave technology The PLANOWAVE 6000 measures the thickness of sheets made of technical plastics such as POM and high-performance plastics like PEEK as well as transparent and advertising plastics like PMMA and PVC-FOAMand glass
