[Case Study] Solved by changing the material from silicone rubber to polyurethane! Extending the lifespan of the rubber fingertips of a robotic hand.
This is a case of material change for the fingertip components of a robot hand used in an automobile manufacturing line. In robot hands that grip metal parts such as automobile components, the edge of the parts repeatedly contacts the rubber, causing the silicone rubber used at the fingertips to wear out and requiring replacement approximately every two weeks. Therefore, the material was changed from silicone rubber to wear-resistant urethane rubber. This change significantly reduced wear caused by repeated contact with metal parts and greatly decreased the frequency of replacements. In actual usage conditions, it has been operating without issues for over a year since its introduction, contributing to reduced maintenance labor and stable operation of the production line.

Robot hand for automotive manufacturing line In the transportation and assembly processes of metal parts, the rubber tips of the robot hand can wear out due to the edges of the parts, necessitating frequent replacements. In this case, by switching from silicone rubber to polyurethane rubber, we improved wear resistance significantly. This change has greatly enhanced the replacement cycle, achieving over a year of continuous use compared to the previous cycle of about two weeks. Additionally, the grip performance of the robot hand varies depending on the weight, shape, and surface condition of the workpiece, requiring different hardness levels. Our company offers hardness selection tailored to applications, such as Shore A 70°, 80°, and 90°. We consider not only wear resistance but also the grip strength needed to securely hold the workpiece, and we propose the optimal polyurethane material accordingly.
