Tōto Springs continuously improves its technological capabilities with an unwavering spirit of challenge, and under the management philosophy of "creating new value," we will continue to develop new technologies to meet diverse needs. Our company has achieved a reduction in assembly processes by integrally forming three thin plate springs. Additionally, we have realized high-speed production of glossy stainless steel wire, which was previously considered impossible, through our unique tooling technology, establishing it over many years. We will also achieve processing that was thought to be impossible with the "know-how" and "new ideas" we have accumulated. Furthermore, we can provide ultra-small wire springs with a wire diameter of 0.035mm and a free length of 3.6mm, which is about half the thickness of a human hair. This is one of the products that demonstrates our high level of technological capability and precision. [Our Technology] ■ Integral forming of three components ■ Automatic forming previously considered impossible ■ Crushing processing of ultra-fine wire (wire diameter less than φ0.1) *For more details, please refer to the PDF document or feel free to contact us.
