Can I stack die springs?
Stack the Die springs only while they are guided. Combined springs are an option as long as the springs are not touching. The larger the conductor, the longer the service life. It is essential to always guide the springs with a free length to diameter ratio (L0 / DH) greater than 3.5.

At what temperature do die springs lose strength?
In the temperature range of 248 to 482°F (120 to 250°C) consider a loss between 1 to 2% of the load every 104°F (40°C).
