Air/water cooling die doubles PE, PP pipe output.The commercial version of the KryoS die from Cincinnati Extrusion GmbH in Austria (U.S. office in McPherson, Kan.) will be shown for the first time in Chicago next month. As we described last December, a prototype was shown at an open house in Vienna last year and was since installed at a customer for long-term production testing. The KryoS die is water-cooled to reduce the melt temperature in the die and also sucks ambient Surrounding. For example, ambient temperature and humidity are atmospheric conditions that exist at the moment. See ambient lighting. air through the pipe to cool it from the inside. The combination of cooler melt and internal air cooling a. 1.

HDPE HDPE abbr. high-density polyethylene pipe exits the die at 330 to 350 F, about 20% cooler than normal, so the pipe shrinks less and hardly sags.

In the days of punch cards, millions of cards were numerically or alphabetically organized by placing them into the hopper of a card sorter, taking them out of all the stackers and putting and reduce the energy
needed by the extruder.
The die will be available in five sizes for pipe diameters from 3.5 to 78 in. and outputs up to 7700 lb/ hr of HDPE. Overall energy savings of up to 30% are claimed. [ILLUSTRATION OMITTED] (620) 241-6843 * www.cet-us.com |
