Dear Mr. Wenlong,

thank you very much for your help. The temperature can be considered as boundary conditions. 

I am currently not sure if the dynamic effect is so dominant. The plastic is heated and then shaped by two moulds (see picture). The force to be applied should be kept constant. Which method do you think would be better for this purpose?

Furthermore, the problem of body penetration has occurred despite weak springs and the use of the pinball region. Unfortunately the target body does not deform as desired. Do you have a suggestion for possible adjustments?

Thank you very much.
