Depending on the application, there are cone shapes, barrel shapes, uneven pitches, and long rolls, among others.
Compression coil springs, commonly referred to as "compression springs," have a proportional relationship between the compressive load and the deflection amount. Depending on the application, they come in conical shapes, barrel shapes, uneven pitches, and long coils (with Aoi Spring achieving a maximum length of 500m). At Aoi Spring, we offer designs tailored to our customers' applications. We also process special materials to accommodate the material requirements suited to the spring's usage environment. With the introduction of state-of-the-art equipment, we can process springs at a rate of 6,000 pieces per hour, compared to the typical 2,000 pieces. 【Features】 ○ Compression springs ○ Proportional relationship between compressive load and deflection amount ○ Available in conical shapes, barrel shapes, uneven pitches, long coils, etc. ○ Proven wire diameters: φ0.1mm to φ22.0mm ○ Custom designs available based on application For more details, please contact us or download the catalog.
