Blown film lines Hosokawa Alpine has upgraded the ExVis controllers for its blown film lines. The controllers are now supplied by Siemens AG, Munich. Besides being included with new Hosokawa Alpine lines, they are also available as retrofits to older machines from the company.
What's new? Control of as many as 120 temperature zones to a variation of less than 1 degree Fahrenheit. The system includes a new Profinet communication platform, motors, drives, PLC and HMI, as well as the new Box PC, a high-performance Siemens computer, with full automation and visualization software.
Benefits Greater control and accuracy, and faster changes in recipe and data acquisition, allowing immediate adjustments for greater performance. In addition, compared to earlier controllers, the Siemens system is equipped with a PC with a wider screen and greater connectivity, with faster data communication speeds. The control system is easy to set up, adjust and use, especially for operators familiar with Siemens systems.
