Hose die head for lower costs and higher quality

The new hose die head from KraussMaffei Berstorff for the manufacture of rubber hoses satisfies the requirements of processors: Increased productivity with higher product quality and lower raw material consumption. KraussMaffei Berstorff is presenting this product at K 2016, 19. – 26.10.2016, Duesseldorf, hall 15, Stand B27/C24/C27/D24

Extremely precise
The special features of the new hose die head are not immediately obvious. The classic configuration has the wall thicknesses in the front head area adjusted via a nozzle that moves axially. The die head attains maximum performance in conjunction with an X-ray measurement system. By implementing it, the user can replace the process of manually readjusting the head with an automated process. The system constantly measures the wall thickness, eccentricity, and outer diameter of the rubber hoses, then adjusts the hydraulic wall thickness centering device exactly to the hundredth of a millimeter by means of digital controllers. The automatic radial centering significantly reduces the adjustment effort at startup and during production – in terms of both time and material consumption. The die head is available for hose diameters of 3 to 100 millimeters.

Optimal quality with high production batches
"The system is excellently suited for manufacturers who want to produce hoses with a uniform wall thickness reliably over a long period, cost-effectively, and with the highest quality," explains Peter Roos, President of the Extrusion Technology segment of the KraussMaffei Group and Managing Director of KraussMaffei Berstorff.

The system provides the hose manufacturer with substantial advantages in quality control as well as operation. Thanks to the continuous, automatic production monitoring, the manufacturer can substantially reduce the time required to adjust the system. This boosts system utilization and cuts personnel costs. Moreover, the reduced thickness tolerance of the wall thickness also brings noticeable material savings, since safety surcharges are largely obsolete. This means that considerable sums can be saved on material costs year after year with consistent quality. The investment in the system pays off in almost no time.
