Design and production
1. Select spring material according to the standard according to the actual product demand;
2. According to the product force value, compression stroke, fatigue degree and other requirements, determine the internal and external diameter, effective number of coils, and the range of wire diameter;
3. Put the relevant parameters into the design parameter formula;
4. It is reasonable and feasible for spring manufacturer to design and produce spring.
