250 Ton Gap Frame Stamping Press – FP 250P
The FP 250P is the largest and highest-tonnage gap frame stamping press in our range, rated at 2,500 kN (281 US tons). Its 0 - 7.87 in stroke and 35.43 x 51.18 in bolster - the largest in the lineup - are built for the most demanding metal forming work. As with every model in the heavy-tonnage range, the 8-point gib-guided slide's contact surface closely matches the bolster's size even at this scale, distributing force evenly and allowing considerably larger progressive dies. Motorized slide adjustment and a hydraulic overload protector are standard here too. Like every Fresan press, it's backed by over 40 years of press manufacturing experience and built for years of continuous production use.
