The reason why spring manufacturers across the country rely on us is that our "hand-winding technology" is alive and well.

Bandai is trusted by many customers as a "spring professional" with a proven track record in proposals for both coil springs and leaf springs. In particular, coil springs are precision components where the load varies finely based on wire diameter, coil diameter, winding direction, and number of turns, yet they are often scrutinized for cost as consumables. During the prototype stage, setup costs and delivery times with NC machines become challenges, but Bandai has established a system that allows for "hand-winding" by skilled artisans. We flexibly respond to special specifications that cannot be wound with NC machines and to short-term prototype requests, receiving production orders from spring manufacturers nationwide. Bandai's strength lies not only in "processing equipment" but also in leveraging "technology and people." If you are facing issues with coil springs, please feel free to consult us. *This type of response is just a small part of the efforts that Bandai engages in daily. Please take a look at the value we can provide to our customers.

The concerns faced in the daily procurement of custom-made processed products, such as "not arriving on time," "unstable quality," "unable to process according to the drawings," and "existing suppliers going out of business," among others. Bandaï's proud custom processing procurement network, the "Hometown Processing Network," consists of unique processing companies from various regions including Hyogo, Osaka, Shimane, Tottori, Hiroshima, Aichi, Kanagawa, and Ibaraki, and it leads to solutions for a wide range of issues related to custom-made processed products. Additionally, in recent years, we have also established a procurement network with reliable overseas processing companies, the "International Processing Network," to strengthen our ability to resolve cost-related concerns.
