Our Mission

Our customer, a medical equipment supplier, located in the Midwest approached Neff Press to design two 15-ton high-speed hydraulic stamping presses. The platen dimensions were 20″ x28″ in between the pins and were nickel plated for anticorrosion purposes. Neff designed the hydraulic power unit around a special long lasting single stage pump (9.4 GPM) with a 20HP electric motor. Neff designed the press with a special RexRoth directional valve, which could tolerate the high flow rates required in this application. A positive stop cylinder was supplied for position control and to generate higher speeds. Eventually, both of these presses were integrated with a roll feed system.
 
The customer required a remote power unit (on casters), and control enclosure. All hydraulic connections from the power unit (3 total) to the crown of the press were to be quick disconnect. The electrical connection, both main power supply and the control wiring were integrated into a mixed power connector to make changeover and maintenance time minimal. These presses can be disconnected from the main control enclosure and the power unit, and another power unit/control center back on line in less than 2 minutes. The presses were designed to run (3) 7-hour shifts, 7 days a week.
 
This customer had bought two similar presses from Neff over 8 years ago and came back for this second application. Neff designed the new presses to achieve 100 Strokes Per Minute, with a ¾” total stroke and ¼” of it being full tonnage (higher speed presses are available). These presses replaced mechanical presses that were not producing the required part quality. Neff’s hydraulic presses and the unique control of hydraulic presses offered this customer higher overall productivity.
