Benefits of Requesting Nondestructive Testing from Tokai Spring Industries

Spring-Specific Testing

While many testing institutions can perform nondestructive testing (NDT) on materials, it’s rare to find institutions specializing in NDT for the countless types of spring shapes and various steel materials.

At Tokai Spring Industries, we select appropriate testing methods based on our understanding of spring applications, including areas where stress concentration and fatigue are likely to accumulate. As a result, we can conduct proper nondestructive testing, not only on springs that already show defects but also on unused springs where destructive testing isn’t an option, helping to reduce the risk of failure.
