Frequently Asked Questions on springs

1. How do I determine the principal dimensions of the springs?
2. Can you custom-produce springs?

1. How do I determine the principal dimensions of the springs?

1. You should first of all check visually whether it acts as a compression spring (nonjointed whorls), as an extension spring (jointed whorls) or in torsion (standard clothes pin).

 

Jointed and nonjointed whorls	Torsion spring

Then you need to measure the principal dimensions of the spring:

 

 For a metre spring, you need to measure:

• the diameter of the wire d
• the external diameter Do
• the length with Lo vacuum

compression metre	traction metre

 

 For a spring of compression, you need to measure:

• the diameter of the wire Ød
• the external diameter ØDo
• the length with Lo vacuum

 

 For a draw-springs, you need to measure:

• the diameter of the wire Ød
• the external diameter ØDo
• the length with Lo vacuum
The length with vacuum is measured with longest inside the loops.

 

 For a torsion spring, you need to measure:

• the diameter of the wire Ød
• the external diameter ØDo
• the length of the clamps E
• the clamps' direction (90°, 180°, 270°, or 360°)

2. Can you custom-produce springs?

Yes, we can. Our engineering department will send you a quote as fast as possible. Contact us on: +33(0)437 496 496
