The compression spring of a professional spring manufacturer is a kind of hardware fitting with a spiral geometry formed by a wire, and hardening and strengthening operations are more difficult than flat hardware fittings.

Design and production

1. According to the actual product demand, choose the spring material according to the standard. 　

2. According to the product force value, compression stroke, fatigue degree and other requirements, determine the value range of the compression spring's inner and outer diameter, effective number of turns, and wire diameter.

3. Substitute relevant parameters into the design parameter formula.

4. It is more reasonable and feasible to design and produce by the spring manufacturer.
