POLYURETHANE SERIES
Polyurethane Round Flat (PRF)
» Large stroke and great flexibility, easy to fit close to workpiece with various shapes
» Large inner support structure to protect the sheet metal from deformation and
damage during
handling process
» Tread pattern efficiently increases the friction force between cups and workpiece in
order to
prevent the oily metal sheets from slipping during the handling process
» Modular structure design rated for quick evacuation and increasing strokes per minute
» Polyurethane material available in 70 durometer,
excellent wear resistance and oil resistance
» Round cups are ideal for sheet metal with different thickness and shapes
Application
» Ideal for sheet metal handling including oily stamping applications
» Applicable for glass, plywood and other stamping materials
