Two springs X and Y have spring constants K1 and K2 respectively. These
are stretched by equal amount by applying a given force. If K1
of these two springs will store more potential energy?*
1. Spring X
2. Energy stored will be same as they are stretched by equal amount
3. Spring Y
4. Energy stored does not depend upon the spring constant of spring.

How to select appropriate constant force springs is a bit difficult for us, even for some professional staff.
And now, this guidance will teach you detailedly, let’s dive in.
Firstly, make sure your application, different application has the different demands for strength, voyage, function.
For instance, the monitor springs have these special features, such as short voyage, strong strength and small housing room.
Therefore, we need to consider these from the beginning, like the thickness and length of 301 SUS stainless steel strip, the multiply load method, the cavity mounting.
Secondly, it’s better to know the method of mounting at the early stage of deal, this will save you a lot of time.

As mentioned before, there are two methods of mouting, drum mounting and cavity mounting, which method be applied depends on the construction of your application.
The method of mounting will decide the diameter of your constant force springs, which will directly affect the proce
How to select the mounting style of constant force spring for your industry?
Normally, there are 2 ways of mounting a constant force spring as mentioned above, one is drum mounting, Another mounting way is cavity mounting.
How to choose one depending on your product, it involves many factors like load force, case room, width, thickness, length, the diameter of coil springs and so on.
You’d better inquiry our expert before deploying it, we will supply you the most suitable design based on our decade’s experience.
How does a constant force spring work(mechanism)?
Constant force spring is made of flat stainless steel strip or carbon steel strip, it will be winded when through the springs forming machine, once extort extension force in the terminal end, it will generate retractable effort.
People utilize this retractable effort to the different applications, such as home appliances up and down function, auto facing in the front of shelf pusher.
How do I calculate tension of constant force spring?
For one constant force spring, We can use the equation to get the tension force of constant force spring directly, the equation is as below:
Tension Force =19400*thickness³*width/6.6/diameter²/1.2 (mm).
If apply the multiple loads, we need to get the summation of each spring’s tension force.
Example: there are 3 constant force springs for retractable function, they are Spring1, Spring2, Spring3, the tension force is as below:
Spring1 Tension = 19400*thickness³*width/6.6/diameter²/1.2 (mm)
Spring2 Tension = 19400*thickness³*width/6.6/diameter²/1.2 (mm)
Spring3 Tension = 19400*thickness³*width/6.6/diameter²/1.2 (mm)
Tension Force = Spring1 Tension + Spring2 Tension + Spring3 Tension
How to make a constant force spring?
First of all, we need to confirm the raw material, different material has a different making technique. Normally, we use the high yield stainless steel strip or carbon steel strip.
Secondly, different width of springs determines which springs forming machine we will use, there are many types of spring forming machines in YongSheng, usually we take the 35mm as the critical point, above it we will use the special large forming machine, if not, we will apply the normal size forming machines.
Thirdly, some special techniques are necessary during springs making like the oil-soaking and high-temperature baking, it will make the springs more lubricating and anti-rust.
All of the above, actually it is a very long way to make the springs by mass production, YongSheng can supply all kinds of flat coil springs with high quality & competitive prices.
What's the life-cycle of constant force spring?
Life-cycle of the springs depends on many factors, such as the spring’s thickness, width, raw materials, load force, work temperature, and so on.
Normally, the larger springs, bigger load force, higher work temperature will have a shorter life-cycle.
Yongsheng can produce the heavy duty constant force spring (Big Springs)?
Yes, we can, Heavy-duty constant force spring usually is used in big equipment for retractable function.
YongSheng can produce various of big constant force spring with our special springs forming equipment, the width of heavy-duty springs is up to 70mm, thickness up to 0.6mm, Our springs products go through a complete testing process before shipment, different environment and application will have the different requirements, inquiry our expert with your application right now!
