A gas spring (10) for forming equipment, a piston rod (16) for the gas spring (10), and a shock collar (18) for the gas spring (10) carried by the piston rod (16). The shock collar (18) may be resiliently flexible, and plastically deformable so as to at least partially collapse, and the piston rod (16) may include features to disrupt a gas spring seal (14) upon at least partial collapse of the shock collar (18). |
