Durability is one of the most important factors in compression spring performance. Our compression coil springs are manufactured using high-quality materials and advanced processing techniques to achieve excellent fatigue resistance and long service life. They are suitable for continuous operation in industrial and mechanical applications.
| To customize the tension spring, you need to provide the following necessary parameter information: | ||
| Wire diameter d: mm | (Note: the diameter of the spring wire) |
|
| Outer diameter D2: mm | (Note: the diameter of the outer circle of the spring) | |
| Length L0: mm | (Note: the free height of the spring) | |
| Number of circles Na: circle | (Note: the total number of turns of the spring) | |
| For customized compression springs, you also need to provide the following technical requirements: | ||
| turn around: | (Description: left-handedright-handed) | |
| Material requirements: | (Such as: stainless steel wire SUS, carbon steel wire SWC, piano wire SWP, copper wire... etc.) | |
| Surface treatment: | (Description: blackening/galvanizing/nickel plating/chrome plating/baking paint/powder spraying/electrophoresis/shot peening/dacromet/electrolytic polishing...etc.) | |
| Pull hook form: | (Description: round hook/semi-circle hook/U hook/middle ear/change hook... etc.) | |
| Strength requirements: | (Note: Elastic performance, other technical requirements, etc.) | |
