Advantages of using Tokai Spring Industries’ products

Reliable Quality

Since the components in rockets and satellites are critical parts of the equipment, they must have absolutely reliable quality and function perfectly.
Therefore the springs used in these components require careful design review, strict quality control, and confirmation test using DUT (Device Under Test).
At Tokai Spring, we have established a system that can provide technical and quality support for such requirements from our clients.
We have a proven track record of working and providing services to many clients in the aerospace industry, from design proposals for springs used in innovative satellites and handling design reviews, to specific quality control standards. We also offer confirmatory tests that reproduce the environment in which the springs will be used.
Furthermore, we have the know-how to design and manufacture springs that can function perfectly even in harsh environments such as cryogenic and high temperatures, and we have the capability to verify the performance of springs through performance tests conducted under conditions that reproduce the harsh environments.
That is why Tokai Spring can provide full and reliable support to engineers in the development of the aerospace industry.
