Compression springs with a load capacity ranging from 18 kgf to 1440 kgf, made of special-shaped wire (square wire).
The angular wire strong spring "DAI spring" is designed for press molds, and by using silicone chrome steel wire with excellent fatigue resistance and deformation resistance to create deformed wire springs (angular wire springs), it generates strong force in a smaller space compared to round wire springs. Extremely heavy loads are color-coded with brown paint. (The paint is also electrostatic coating, making it difficult to peel off.)

Company information
Sotec Co., Ltd. is a mail-order company founded in 1947, known for its reliability and achievements as Daido Spring Co., Ltd. We offer standard springs called "Tri-Spring" and strong rectangular wire springs known as "Die-Spring." The Tri-Spring includes over 15,000 types of standard springs such as compression springs, extension springs, torsion springs, and circlips. The Die-Spring is a rectangular wire spring that generates strong force in a small space and is utilized in various fields, including machinery, tools, and press machines, taking advantage of its unique characteristics. Both types can be ordered from a single piece and are shipped on the same day. For bulk orders, if you provide us with your annual usage numbers, we can offer you the best prices and contribute to cost reduction. Additionally, we are open to consultations regarding custom products, prototypes, and mass production that are not available as standard items.
