How to custom made gas springs(gas struts)

A if you have the drawing of the gas spring(gas struts) ,send the drawing to our email:

sale@gas-springs.cn

B if you have the sample of the gas spring, the best is that send the sample to our factory

C:if you don't have the sample or drawing ,we can help you making the gas spring drawing

Step 1: get the stroke length of the gas spring

Step 2: get the extended length of the gas spring

Step 3: get the force (F1) of the gas spring

F1=extension force piston rod extended
F2=extension force piston rod retracted
F3=compression force piston rod extended
F4=compression force piston rod retracted
Fr=friction force=F3-F1,F4-F2
Fa=(F1+F3)/2

Step 4: Tell us the extended speed of the gas spring (mm/second)
