Before implementing the UFIBER solution, the customer manually removed burrs, which required approximately 15 minutes (900 seconds) per part or 25 hours per batch. With the UFIBER solution, the process time was reduced to just 60 seconds per part or 1.7 hours per batch, achieving a 93.33% time reduction or a 15-fold improvement in efficiency.
