Function
Flex FormTM
To obtain a complete system the following data is required:
• Number of pressure points
(maximum six CFF to one FFG)
• Needed tonnage for the system
• Production rate parts/minute
• Max high before stroked (L max)
• Used stroke length
• Max press velocity during stroke length (m/s)
• Needed return force
Requirements
Flex FormTM
• High Force Hydraulic System up to 12 ton with a single cylinder• Low Contact and Return Force
System provides a soft hit and very low reverse force to decrease press wear.
• Constant Force System has no pressure rise which
provides constant force through entire stroke for better control of part quality.
• Flexible Orientation Flex Form system can be used in upper
or lower applications.• Delayed Return Option Cylinders can be delayed Applied stroke length optionally
• Self Contained Option
The system can be provided
fully filled, bled, and ready to
be installed.
