Compression springs with a load capacity ranging from 50 kgf to 1250 kgf, featuring irregular shapes (square wire).
The angular wire strong spring "DAI spring" is designed for press molds and generates strong force in a small space compared to round wire springs by using silicone chrome steel wire with excellent fatigue resistance and deformation resistance to create shaped wire springs (angular wire springs). The ultra-heavy load is color-coded with black paint. (The paint is also electrocoated, making it difficult to peel off.)

basic information
The irregular wire (angle wire) compression spring for ultra-heavy loads (BLA/DSG) is painted black, and the deflection after 300,000 uses is 20% of the free length. For an outer diameter of 10mm (allowable load 50kgf), the free length ranges from 15 to 100mm. For an outer diameter of 12mm (allowable load 75kgf), the free length ranges from 20 to 100mm. For an outer diameter of 14mm (allowable load 97kgf), the free length ranges from 25 to 100mm. (omitted) For an outer diameter of 35mm (allowable load 630kgf), the free length ranges from 30 to 200mm. For an outer diameter of 40mm (allowable load 820kgf), the free length ranges from 35 to 200mm. For an outer diameter of 50mm (allowable load 1250kgf), the free length ranges from 50 to 20mm. It also complies with the RoHS directive.

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 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 wire spring that generates strong force in a compact space, utilized in various fields including machinery, tools, and press machines, taking advantage of its unique characteristics. Both types can be ordered from just one 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 price, contributing to cost reduction. We also welcome inquiries about custom products, prototypes, and mass production that are not available in standard offerings.
