Online quality control of optical fibers in the drawing tower
By means of a drawing tower model, SIKORA presents live its broad portfolio of measuring systems for quality control of optical fibers at different positions. There will be systems presented for the measurement of the diameter and the position of the naked and coated fiber as well for the determination of the tension.
Furthermore, gauge heads are displayed for the measurement of the fiber temperature at the hot position of the drawing process, to determine the fiber temperature for the control of the furnace, and at the cold end, to exactly dose the Helium used for the cooling, and therefore, to save costs.
In addition, a gauge head for the measurement of the concentricity of the coating as well as for the detection of lumps on the surface of the coated fiber is exhibited. Online inspection and sorting of XLPE and semiconductor pellets
A further highlight at the wire is the PURITY SCANNER for online inspection and sorting of plastic pellets that are used for the insulation of medium, high and extra-high voltage cables as well as onshore and offshore cables.
The unique combination of an X-ray camera with an optical camera system is currently the only technology that reliably detects contamination on the surface as well as inside of plastic pellets. Contaminated pellets are automatically sorted out. Offline inspection and analysis of pellets, flakes, and films/tapes
SIKORA engineers developed the PURITY CONCEPT Systems for small material throughputs and applications where sample testing or an incoming goods inspection is sufficient. These analysis devices are alternatively equipped with X-ray technology, optical cameras or infrared sensors and detect contamination in pellets, flakes, and tapes.
For example, the PURITY CONCEPT Systems are used to analyze pellets that have been detected and sorted out by the PURITY SCANNER. Another typical application is the testing of tapes that are used when manufacturing factory joints.
The interplay of online and offline inspection and analysis provides an absolute control of the material purity as well as the development of a database to further improve processes and avoid future contamination.
