We will redesign the improved version of the spring with insufficient strength.
The spring in the photo is a torsion spring designed and prototyped by our company. We received the actual spring because it was reported to be deformed during use. After discussing the situation and calculating its lifespan, we found that its strength was insufficient for the stress (load) during use, so we proceeded with redesigning and prototyping. The material used is "Piano Wire Type A, SWP-A." We selected specifications to improve durability without changing the force (moment) when twisted. (Surface treatment has been applied for storage as a sample.) Our company handles the design and prototyping of torsion springs. If you provide us with general conditions such as the space for the spring and the desired force, we will propose the optimal specifications and create a prototype. Our technical staff will respond carefully, so please feel free to consult us. Tsuruoka Spring Co., Ltd.
