The STAHL Super-Mulde is a truly unique feature in trough technology. Only thanks to its raised feed area does STAHL’s dimensionally stable trough technology offer you an actual wrap angle of 180° under contact pressure. The use of this technology increases the flattening distance under contact pressure by up to 20 %. In addition, STAHL troughs made of gray cast iron or steel ensure excellent heat retention and even heat distribution. Unlike, for example, lower-quality heating bands or aluminum molds, STAHL molds remain absolutely dimensionally stable even under extreme temperature fluctuations and maintain the set ironing temperature much longer during ironing without the need for continuous reheating. In addition, steam-heated STAHL hot mangles feature a split steam distribution system within the machine. This ensures that only the first half of the trough, across the entire working width, receives a concentrated supply of fresh steam to maintain a constant ironing temperature. All of this promises you maximum performance with optimal energy efficiency and, above all, first-class finish quality.
