Extrusion International 3-2019

26 Extrusion International 3/2019 PIPE EXTRUSION The adjustable calibration sleeves for the pipe diameters 14 to 2.500 mm are patented products for practical solu- tions to optimize complex production processes. They are developed to precisely match the customers‘ production requirements. And the sleeves are continuously adapted to the latest state-of-the-art technology in order to im- prove the calibration speeds and to reduce the costs. Adjustable calibration sleeves with easy and robust ad- justment By means of the CCA adjustment unit, the calibration sleeve can be adjusted. During ongoing production, you are able to • Compensate differences in the shrinking characteristics of various materials and wall thicknesses • Improve the pipe tolerances • Shorten the retooling time considerably • And thus increase the availability of the extrusion lines, improve the pipe quality, save material Ovality adjustment Four adjustment points allow the adjustment of both the diameter and the ovality of the calibration sleeve. In this way it is possible to counteract the ovality during the pipe production so that a „round“ pipe can be manufactured. CCA looks forward to presenting their adjustable calibra- tion sleeves at the K 2019 in Düsseldorf, Germany – booth G58, hall 10. CCA GmbH Werkstr. 10, 32584 Löhne, Germany www.ccagmbh.de CCA GmbH, based in Löhne, Germany, develops reliable high-performance solutions for plastic pipe extrusion. The high-quality calibration sleeves are used successfully all over the world. Quality and Innovation for Plastic Pipe Extrusion
