Cincinnati Extrusion GmbH said its KryoSys is a new system to make polyolefin pipe.
The machine combines a high-speed extruder with a newly developed pipe die, called the KryoS die, plus a very efficient cooling section and a heat-recovery system, according to the company in Vienna, Austria.
KryoSys lines are designed to produce smooth-wall single- and multilayer pipe from polyethylene or polypropylene, in dia¬meters from 4.4 inches to 80 inches. They also are suitable for the extrusion of corrugated pipes, Cincinnati Extrusion said.
A key component, the spiral-mandrel pipe die, features an innovation that begins cooling the melt inside the die. This cuts in half the length of the cooling section required and reduces energy consumption by up to 30 percent. The lower melt temperature also brings a significant increase in viscosity when the melt comes from the die, which counteracts the tendency to sag, especially in thick-wall pipe.
The KryS die also features a large internal aperture, which allows air cooling for the extruded melt.
The extruder maker's U.S. subsidiary, Cincinnati Extrusion Inc., is in McPherson, Kan.
