Screen includes profibus connections.
Original Press Release:
KREYENBORG Integrated System Consisting of Backflush Screen Changer and Extrusion Gear Pump for Film Production
With their innovative product line, The KREYENBORG Group has secured its place among the world's leading manufacturers of plastics extrusion equipment. The KREYENBORG name has become associated with reliable, high performance solutions built to the tightest quality standards.
KREYENBORG is currently involved in a project for Polypropylene co-extruded flat film. Maintaining strict gauging tolerances and high visible clarity are critical in the final film product.
The material is extruded, filtered and run through a slot die. For further process stability, a KREYENBORG melt pump was installed to guarantee pressure consistency at the die.
- 700 kg/hr extrusion output
- 31 micrometer particle size filtration
- Long screen life
- Minimal operator input
- Strict gauge control and special visible clarity of film
The performance of the KREYENBORG back-flush screen changer far exceeded the customers' expectations in processing of different materials and has proven absolutely precise and very effective. Through repeated back-flush sequences, the filtration system demonstrated its ability to regain the desired differential pressure under production conditions. The automatic air ventilation action of the RS series screen changer and the metering effect of the GPE series melt pump provide the ability to run production through back-flush and screen change with no loss in quality. As part of this project development special screen packs with an innovative weave structure are being tested to significantly increase the clarity of the film.
As announced at K'2001, KREYENBORG back-flush screen changers are now fitted with our new profibus connections. Advantages of profibus are lower wiring costs and higher serviceability of the machines as well as cost savings in engineering and start-up.
