Advantages of using Tokai Spring Industries’ products

Trustworthy durability and corrosion resistance

The driving gears of ferris wheels, especially those installed in coastal areas, must use springs that are durable and resistant to corrosion.
This leads to the problem of rustproofing for springs. It is easy to presume that the effectiveness of the rust-preventive treatment is sufficient as long as it prevents the springs from rusting. However, unlike steel parts that do not undergo large deformation, springs have a broad elastic range. That is why rust prevention treatment for parts that repeatedly deform, such as springs, runs the risk of the paint peeling off during use. Therefore, it is necessary to select a base treatment that does not peel off even if the spring is repeatedly deformed and a rust prevention treatment that can suppress corrosion even through long-term use on the coast.
Tokai Spring has the expertise in designing and manufacturing springs that are used in harsh environments, such as along the coast for a long time, using rust preventive treatments with a multi-layer coating.
It is one of our main strengths to produce durable springs that can be used for applications such as the ferris wheels’ driving gears.
