PRODUCT SELECTION & INSTALLATION GUIDE COMPOSITE SPRINGS VIBRATORY CONVEYORS AND SEATING FEATURE BENEFIT • Exceptional fatigue resistance • Corrosion resistance • Creep resistance Fewer failures for longer spring life, less frequent replacement, and a more reliable end product • High strength-to-weight ratio—less than half the weight of steel • High spring rate and deep deflection • Custom designs to support off-axis loads Stronger springs can mean fewer are needed in an application for overall cost savings • Common sizes in inventory • Custom design and finishing capabilities Fast, dependable service, ready-to-install product and customization options to boost your manufacturing efficiency PRODUCT DESCRIPTION Thermoset composite springs from Avient are engineered with proprietary vinyl ester or epoxy resins and unidirectional fiber reinforcement technologies. Mechanical stop required: In chair installation and applications, a mechanical stop must be added to the chair design to prevent over-stressing of the spring. Processing conditions can cause material properties to shift from the values stated in the information.
