As one of the ace extension spring manufacturers, Hetai Spring Manufacturing brings to you over half a century of spring design and manufacturing excellence. We offer an extensive varieties of extension spring, intelligently designed to absorb and store energy and create a resistance to a pulling force. Initial tension determines how tightly together springs are coiled. The initial tension is equal to the minimum force required to separate adjacent coils. This initial tension can be adjusted to achieve the load requirements of your particular application.
Extension Spring - Assortment of End Loops or Hooks
There are many different types of end loops or hooks that can be used with extension springs. The most common types of ends include machine hooks, full loops, cross-over center loops, centered hooks or eyes, and swivel hooks. At least one of these is suitable for your applications.
Extension Springs - Value Driven Services
Being one of the most reliable extension spring manufacturers, Hetai Spring has the capability to duplicate almost any end required, or design the correct end for your application. We have a rich and varied experience in manufacturing different types of springs for a myriad of industry verticals. From design to manufacturing to technical support, we are your go-to firm for reliable and durable extension springs. Hetai Spring Manufacturing also caters to unique spring requirements pertaining to fatigue strength, stress levels, load and deflection, among other parameters.
Conical (Spiral) Springs
This spring is fabricated in the shape of a cone. It is wide at one end, and tapered at the other. A conical spring is often used in compact spaces as their height is less than a uniform-diameter compression spring. If buckling is a concern in your application, a conical spring is recommended.
A helical spring could have a cylindrical, square, or even rectangular shape with a number of coils. However, the cylindrical helical spring is widely used. These springs can be manufactured in several different configurations.

Replacement Mech Mechanism Recliner Tension Spring
1. What is initial tension (extension spring)?
Extensions springs require a certain amount of force to be applied before any deflection is realized. Deflection is the point where the coils start to separate and the spring extends. Once the initial tension is reached and the spring will start to expand at the predetermined rate of the spring.
For example if a spring has an initial tension of 20 lbs. and the spring rate is 15 lbs./in.. It will take 35 lbs of force to pull the spring apart one inch, 20 lbs. of initial tension and 15 lbs of spring rate. To expand it to two inches it will take 50 lbs of force, 20 lbs of initial tension and 15 lbs for each inch. And so on and so on.
2. How long will a spring last?
A correctly designed spring, without any extraordinary stress will last indefinitely. Designing a spring based on its operating environment is necessary to increase the life of the spring. If the spring is in a corrosive environment, or under extreme temperatures, the proper material must be used in the design of the spring. Using a stainless steel material, or putting a protective finish on the spring according to the elements involved will increase the life cycle of the spring.
3. What is the proper deflection of a spring?
Deflection refers to the distance a compression spring is compressed, the distance an extension spring is extended, and the distance a torsion spring is rotated. Every spring is designed with a certain amount of safe deflection. If a compression spring is compressed more than its safe deflection it will begin to take a set, and not come back to its original height. If an extension spring is extended beyond its safe deflection the spring will begin to increase in length as it is returned to its original position. The same is the case with a torsion spring, if it is wound beyond its safe deflection it will take a set and not unwind to its original starting position.
