Compression springs with a load capacity ranging from 18 kgf to 1440 kgf, made of irregular cross-section (square wire).
The angular wire strong spring "DAIspring" 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 deformed wire springs (angular wire springs). Extreme heavy loads are color-coded with brown paint. (The paint is also electrocoated, making it difficult to peel off.)

basic information
The extreme heavy load (BRO/DSB) of the irregular wire (angle wire) compression spring is painted brown, and the deflection after 300,000 uses is 20% of the free length. For an outer diameter of 6mm (allowable load 18kgf), the free length ranges from 15 to 60mm. For an outer diameter of 8mm (allowable load 33kgf), the free length ranges from 10 to 80mm. For an outer diameter of 10mm (allowable load 45kgf), the free length ranges from 10 to 90mm. (omitted) For an outer diameter of 40mm (allowable load 640kgf), the free length ranges from 40 to 300mm. For an outer diameter of 50mm (allowable load 1000kgf), the free length ranges from 50 to 300mm. For an outer diameter of 60mm (allowable load 1440kgf), the free length ranges from 60 to 300mm. 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.
