HASSFURT, GERMANY (Oct. 3, 11:10 a.m. EDT) — Unicor GmbH, which makes pipe corrugators in Hassfurt, will present its new Unicor compact die head at K 2007.
The die-head systems are designed for pipe with diameters of 10-24 inches. The technology improves pipe quality and reduces tooling changeovers to different sizes of pipe, according to the company. 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 compact die head reduces that changeover because the recentering step can be omitted, 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.
