Custom Precision Springs—Engineered for Aerospace Innovation

At Tokai Spring, we design and manufacture high-precision springs for critical aerospace applications—from rockets and satellites to asteroid exploration systems. Our springs support vital functions such as deployment systems, release mechanisms, and payload instruments, where reliability and precision are essential.

Specializing in small-lot production (1 to 5 pieces), we work with complex designs and advanced materials that many others cannot handle. Even without detailed drawings, we provide full support from concept to completion.

Through close collaboration with aerospace agencies and research teams, we help turn ambitious space missions into reality—with Japanese craftsmanship and proven performance.
