20 Ton Gap Frame Stamping Press – FP 20P
The FP 20P sits third in our five-model flywheel-driven range of gap frame stamping presses, rated at 200 kN (22 US tons). Its continuous-operation speed steps down slightly from the smaller models, to 160 strokes per minute, with a 0 - 1.97 in stroke range and a 14.17 x 21.65 in bolster. It's well matched to light-tonnage, high-volume punching and blanking work, and its frame accommodates noticeably larger dies than the FP 10P or FP 15P. Like every Fresan press, it's backed by over 40 years of press manufacturing experience, ready for sheet-feeder integration and years of continuous use.
