FlexPLY spring Composiflex designs and manufactures a variety of E-glass/epoxy, carbon/epoxy, and high-temperature glass/epoxy FlexPLY® springs for numerous industrial equipment applications. These flat springs are most commonly employed within the drive systems of vibratory equipment where they are loaded in bending and excited at their natural frequency. This provides the maximum deflection of the springs which translates to the maximum rate for transfer of bulk material through the vibratory conveyor or feeder. It also requires a highly fatigue-resistant material that can sustain tens of millions of load cycles without failure. Further, applications that are tuned to a particular spring performance require spring rate stability over cycle life. When designed within target stress limits, FlexPLY® springs provide exceptionally long fatigue life, typically with 5% or less change in spring rate over time.

FlexPLY spring Because of its high fatigue resistance, FlexPLY® material is well-suited for components other than springs. This material is a candidate for any component in which fatigue is an issue and/or maintaining consistent stiffness is important. The material can be laid up in sheet form, cured, and cut to final shape using our 5-axis CNC router or 3-axis abrasive waterjet cutter.  It can also be laid up into complex molds to produce a near net shape component right out of the tool.
