A manufacturer of robotic assembly systems was struggling to hold tight tolerances on acetal fixtures for electronic components. The fixtures were growing out of the specified tolerances as a result of thermal expansion. These dimensional changes were interfering with the function of the robots. Material holds tight tolerances when temperature fluctuates The lead engineer for the company reached out to Curbell Plastics to discuss the problem. She worked with Curbell to identify a dimensionally stable polymer that was able to hold the required tolerances even when the fixtures experienced temperature changes. This allowed the robotic assembly machinery to function properly. Looking to hold tight tolerances in thermal conditions? We're here to help.
