56 Extrusion International 5/2023 FAKUMA 2023 Measurement of tubes and pipes by means of millimeter wave technology In the area of extrusion, SIKORA presents the CENTER - WAVE 6000/250 for the measurement of tubes in the diameter range from 32 to 250 mm during production based on millimeter wave technology. All dimensions of the tube, such as the diameter and the wall thickness, are determined and visualized in real time over 360 de- grees of the pipe circumference. The measurement data obtained enables automatic control of the minimum wall thickness, taking into account the standard devia - tion of the extrusion line. This allows potential savings to be exploited to the maximum. In the line, the system enables gapless, reliable quality control as well as auto - matic control. The model is characterized by its simple operation. At the push of a button, the operator imme - diately receives continuous and precise measured val- ues, without presetting the product parameters, with - out the influence of a coupling medium and without any calibration. The exhibited CENTERWAVE is only one model out of a comprehensive product family offered by SIKORA for the measurement of different product diameters from 32 to 3,200 mm. Measurement of tubes and hoses by means of X-ray technology for single-layer and multi-layer applications For more than 30 years SIKORA has been offering X-ray technolo- gies for quality control and en- ables manufacturers a reliable inline quality control of stranded products. How to reliably mea- sure different layers of tubes and hoses during the extrusion process is demonstrated at the SIKORA booth by the X-ray measuring sys- tem X-RAY 6000 PRO in combina- tion with the processor system ECOCONTROL 6000. At the 22" monitor the measuring values are displayed numerically as well as graphically as trend and statistical data. By default, the wall thick - ness is displayed at eight measuring points. In addition, an intelligent physical evaluation model determines the minimum wall thickness, i.e., the available value, which optimally supports the user in controlling the process. The physical model also allows the wall thickness to be visualized over the entire circumference of the tube or hose at any point. The user selects howmany points and at which position the values are to be displayed. The processor system is also used for au- tomatic control of the line speed and extruder rpm. It thus guarantees the compliance with the given specifica - tions as well as highest performance for a maximum of process optimiza- tion and productivity. The X-RAY 6000 PRO can be used for product diameters from 0.65 to 270 mm. For products where a single layer measurement is required, SIKORA presents the X-RAY 6000 PURE to the Faku- ma visitors. Also using X-ray technology, the device measures single-layer products as well as the total wall thickness of multi- layer products and covers with two models product diameters from 6 to 110 mm. The measured values are visualized on a 15" dis - play; if required, automatic control to mini - mum wall thickness is also possible. Ensur- ing quality while saving material leads to a significant increase in productivity and also contributes to save CO 2 and thus to protect the environment.
