Silicon products - made perfect with PC-based Automation
Different chemicals need to be dosed and mixed exactly in the manufacture of silicon products. A chemical reaction must be induced by adding heat, at the same time the process of exothermal reactions must be controlled by cooling. This requires great technological know-how and a flexible, efficient and reliable automation. The Hanse Chemie in Geesthacht relies on PC-based Automation from Siemens. SIMATIC WinAC and WinCC run on an industrial PC and are the best basis for further technological innovations.
Is the PET material cycle really closed!
PET (polyethyleneterephtalate) is one of the materials you can find everywhere in the modern household - usually in the form of bottles.
All the more important to return PET to the material cycle by recycling.
But the material cycle could never quite be closed despite the greatest
recycling efforts. A frequent source of annoyance for the Swiss Uzwiler
Bühler AG. The company has now solved this problem with its new
"bottle-to-bottle" process. The heart of this process is the PET ring
extruder: 12 screw conveyors, dosing unit, filter and cooling assemblies
operate with the SIMATIC WinAC software PLC.
This PC-based solution is not just a lot cheaper. It has also proven very reliable and supplies the PET raw material in a quality which is hardly distinguishable from new PET. The most pleasing thing for the customer is the high degree of automation. Just one press of a button - and the process runs automatically. |
