          The Irwin Model 52 Forming Station is state of the art in innovation and technology for solid sheet thermo-forming. Its Computer Adjustable Shut Height System (CASH) uses a measuring device to check loads on the frame, allowing the tonnage limits to match and not exceed the machine specifications. The system monitors former pressures and thermal variations which in turn keeps the shut height accurate to ±.001" on each corner.
          The Model 52 also has an advanced form air and vacuum system, utilziing the latest technology available, offering valves with 100 CV flow rate and a reaction time at 22ms and accuracy ± 1.0% full PSI, and an optional vacuum bleed servo valve with a full-scale reaction time of 180ms and an accuracy of .09°.
