Machines and systems for surface coating - Import export

The new QuellTech Q5 Laser Scanner Series combines the advantages of small form factors with both high resolution and scan rate. The sensor disposes of different set-up possibilities with respect to the analysis algorithm. Measurement results are delivered via Ethernet, calibrated in the X / Z plane. Special adjustable algorithms can be selected, extremely useful particularly also for optically most demanding surfaces. Time-consuming calibration tasks for the user are no more required, as the calibration routine runs on board. High Scan Rate with up to 14,000 Profiles per Second Due to an appropriate limitation of the image range (AOI) in X and Z direction, the scan rate could considerably be increased. High resolution and detection frequency with up to 14.000 profiles and 28 Mio. points per second •X measuring range from 10 to 1022 mm •Z measuring range (height) from 5 to 878 mm •Laser wave length blue 405/450nm, red 650nm

Particular Challenges: In the course of the production, endless cables are running at a considerable speed, and supervision has to be carried out nearly under real-time conditions. The size of the objects to be determined, i.e. of the flaws to be discovered, is in the range of only some hundredths of a mm. Another difficulty is the fact that surfaces with very different reflectivity and roughness are involved. In order to be able to check the cables all around, several laser scanners must be in place, mounted at different angles, thus covering the entire range of 360°. Quelltech Solution: The solution consists in a configuration of four Q6 laser scanners, mutually displaced by 90°, so the entire surface of the cables is in the field of view. On the basis of the 100% inline inspection, the position of defects can precisely be determined, without losing too much time.

Functional and decorative coating systems In addition to coatings for Coil Coating applications and related areas, SI-Coatings GmbH develops and produces individual paints and varnishes for any application. These are technical, functional and decorative coatings.

high performance coating of sophisticated parts

This coating system is mainly used for the coating of cold rolled strip, but can also be applied to other metals. It is applied in the last processing step and enables a special gliding ability and heat resistance on coated surfaces.
