Unicor GmbH, which makes pipe corrugators in Hassfurt, will present its new Unicor compact die head at K 2007, set for Oct. 24-31 in Dusseldorf, Germany.
The die-head systems are designed for pipe with diameters of 10-24 inches. The technology reduces tooling changeovers to different sizes of pipe. Until now, Unicor said, a change of pipe dimension required demounting and remounting at the die head and the mouthpiece. That meant the die head had to be recentered.
The Unicor die head eliminates the need to recenter, since that is now a fixed element.
Unicor also developed a new spiral mandrel distributor, also delivered with fixed centering. The distributor improves qualities of the inner and outer pipe, eliminating unwanted striation, Unicor said.
