Introduction nitrogen gas spring
The tool and die nitrogen gas spring (nitrogen gas cylinder or gas spring) is using the nitrogen gas pressure creates a force that is proportional to the surface area on which it makes contact.
The piston rod in the gas spring is used as a spring element.
The advantage of the nitrogen gas spring is that can generate a much greater force and longer stroke than an equivalent mechanical spring with small cylinder body and stable wokforce.
Normally its life cycle is one million times. Therefore, its life cycle costs are the considerably lower than other metal springs.
The nitrogen gas can be easily checked and regulated; thus this kind of spring is far superior to any other types of springs.
It could simplified your mould or die design; meanwhile you could design a linked system tomonitor orcontrol.
