Can you make plungers with a specified end force?

Yes this can be done.

Question:

We are designing a satellite.  We need to incorporate separation springs and deployment springs into the satellite. Thus, our requirements dictate a maximum force that can be applied on our springs.

What we need are spring plungers similar to Vlier SSMD51P but 2 with a max end force of 3 Newtons and 2 with a max end force of 3.3 Newtons.

Additionally, the material needs to be space grade i.e. does not outgass (stainless steel).
