- Expert Tip
A proper heat-treatment of the springs at 300°C is essential and gets the best results for high quality springs. If a spring does not get heat-treated properly at the right temperature - the loss of height is much bigger.
The spring test shows you the different loss of heights of 3 springs with same specifications but heat treated at different temperatures: first spring at 0°C – second at 150°C – and the third at 300°C.
A perfect heat-treatment guarantees a high quality spring, avoids sagging and saves wire.
It is worth to check temperature on your machines.
Temperature sticks are available at Spühl.
