Concave Compression Spring

The concave and convex helical compression springs are similar to tapered conical helical springs. The concave compression spring mainly used as cushion spring and convex coil spring can replace the tapered or unequal pitch cylindrical coil spring, such as valve spring.

The concave compression spring under load is relatively complex. Some spring coils are in plane contact with the support base; some of them touch other spring rings. The contact between the spring coils mostly occurs in the middle part of the spring and only when the whole spring is close to full compression and combination. Therefore, in order to simplify the calculation, the compression and combination of the spring is regarded as the plane contact between the spring coil and the bass.

Q:What is your main market?

A:North America, South America, Australia, Europe, The middle east, and etc.

Q: Will there a sample before bulk order?

A: Yes. You can ask a sample for testing first. For little quantity, we suggest place the bulk order for us, and we make a sample for your confirming before the bulk order to save your sample cost.
