Vacu-Grip vacuum fixtures are ideal production tools. Many have been in production for many years and used for thousands of trim cycles. Ravin LM's are ideal for short-run programs. We recommend 20-50 cycles, however, their longevity is highly dependent on how the surface is treated throughout the layup process. The low CTE base material will last for hundreds of cycles (If not longer); however, our surface coatings are off the shelf solutions with limited life before they require re-finishing. Call us to find out if this is the right solution for your application.
