Benefits of Requesting Fatigue Testing from Tokai Spring Industries

Contributing to the Reliability of Your Products

While many testing institutions can perform general fatigue testing, Tokai Spring Industries specializes in fatigue testing specifically for springs. We analyze fatigue test results based on springs’ unique behavior and provide concrete suggestions for design improvements and performance enhancements.

For example, we offer expert insights into where fatigue is likely to occur, or under what conditions springs will experience failure based on their usage and operating conditions.

In addition to vertical compression fatigue testers, we own specialized testing machines designed to evaluate the durability of disc springs used in machine tool spindles by stimulating spindle shafts. We also have equipment for measuring rotational torque for various spring shapes, such as torsion springs, coil springs, and torsion bars.

This enables us to conduct fatigue testing that closely replicates real operating conditions. The test results not only contribute to product design but also allow us to propose ways to improve performance and durability.

By consulting us in the prototype or early product development stages, we can design and manufacture jigs that simulate actual equipment, evaluate durability, and contribute to the optimization of your product development.
