Guide Line - Spring selection and operating condition :
- Select the spring carefully at the design stage.
- For longer stroke - select light load or medium load spring.
- For more load - select heavy load or extra heavy load springs.
- Calculate spring stroke (required compression.)
- Pre-loading compression should be equal to 5 % of the length.
- Use guide pin, a locating bore as a guide - this is essential for spring having a free length / diameter ratio exceeding 3.5
- If possible use longer springs for lower loadings.
- Never compress springs beyond the average life load and compression.
- Always check spring holder heights and working strokes of moving elements after die tools has been reground.
- Protects springs from corrosive agents.
- Do not exceed a working temperature of 2500 C, No significant load reduction occurs up to 1200 C, beyond this temperature an average loss of 1 % for every 400 C must be calculate.
- Do not replace one spring at a time, if they are multiple in use.
- Do not alter physical characteristics of springs like cutting of coils, grinding of internal or external diameter.
