Advantages Of Choosing Our Spring Products and Services

1. Fatigue Resistance and Long Lifespan

Springs used in marine engines for long voyages are required to have the perfect fatigue resistance and a long lifespan. Our thorough and unique process-control (heat treatment, shot peening, non-destructive inspection process*) helps provide a safe voyage.
* The majority of Tokai Spring’s engineers have JSNDI level II or higher

2. Long-term Safety Due To Corrosion Resistance

One of the biggest challenges in the industry is corrosion. According to the intended use, Tokai Spring can propose spring designs that are resistant to salt corrosion by utilizing data on materials and rust prevention. Tokai Spring produces springs that can be used safely for a long time by avoiding problems with corrosion.

3. Trustworthy Reproducibility

When replacing springs used in ships and submarines, it is important to be able to manufacture and provide springs that have the same shape and characteristics as the original. At Tokai Spring, we keep drawings and the production data of springs manufactured in the past so that we are always able to reproduce a spring whenever necessary.
