Working together to understand the unique requirements for the company’s conveyor application, the engineering team at Avient developed customized flat springs that provide more consistent quality and longer fatigue life than the original components, improving conveyor performance and longevity. THE IMPACT Not only did the Gordon Composites vibratory springs outperform the company’s originally specified spring components, they provided a number of additional benefits: Ready-to-install springs reduced labor and simplified installation Unlike alternative springs, Gordon Composites springs are factory machined to the required size and pre- drilled for a significant reduction in cutting and drilling processes and allowing valuable labor time to be allocated elsewhere.
