Neff Press Custom Applications: High Speed Stamping
Final Product: Medical Device
 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.
Neff has over 40 years of experience manufacturing, engineering
and integrating industry standard components to solve customers
manufacturing needs. Contact Neff at 800-325-8612 for further details
