Chuobane Co., Ltd. specializes in manufacturing springs using color wire (resin-coated materials).
In the accompanying image, you can see our "resin-coated springs (red)" alternating with standard "SUS springs" on display.

We are pleased to announce the completion of our red color springs. These springs are designed for use in ballpoint pen click mechanisms. Imagine how charming a transparent ballpoint pen would look with a red spring inside!

At Chuobane Co., Ltd., our color wire springs are made by applying a resin coating to spring materials such as SUS (stainless steel) or SWP (steel wire piano). We offer a wide range of color options, so please don't hesitate to inquire about your specific needs.
Our resin-coated springs provide the same level of performance as SUS materials while offering additional benefits such as chemical resistance.
Developing this resin-coated material to perfection required numerous trials and errors. We're proud to have finally achieved the desired result.

If you have any concerns about springs, please feel free to contact Chuobane Co., Ltd. We're here to help!
