Types of Springs and Differences between them

A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment. If you take apart anything mechanically related, chances are you'll find one.  A spring is a mechanical device that can pull, push, wind, support, lift or protect.

There are a variety of spring types available, and the most common way to classify springs is by force or torque needed by the application and the operational conditions. The most common spring types include:

 Compression spring: 

- designed to operate with a compressive load and found in shock absorbers, spring mattresses, mechanical pencils, and retractable pens.

By far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. A compression spring has superior compression spring strength and it is an open-coil helical spring that offers resistance to a compressive force applied axially.

Compression spring information - Key compression spring specifications include the spring rate, helix type, spring ends type, wire diameter, material, the various diameters, and free length  Under increasing load, the space between coils closes until the spring's compressed length is reached, when the coils touch.

Compression spring stainless steel are used primarily in manufacturing applications, where a variable and opposing force is required between components. The ends can be open (left as cut) or closed (where the last coil flattened against the adjacent coil to produce a more square end relative to the axis). Squaring the ends may also be achieved by grinding the surface of the last coil.  
This kind of spring is generally of equal pitch, the main shapes are: cylindrical, conical, convex and concave, and a small amount of non-circular, so there is a certain gap between the compression spring ring and the ring , Then the spring can contract and deform when subjected to an external load, which can store deformation energy. For compression springs, Xulong spring is helical compression spring manufacturer in China and we have manufactured them for clients in the filed of military, automotive, outdoor equipment,agriculture,power and gas etc.

● Torsion spring: 

-designed to operate with torque (twisting force); powers every clothespin and mouse trap.

Torsion springs are helical or flat spiral coils or strips used to apply or resist torque loads. Key specifications include the spring rate, spring ends type, wire diameter, material, and the torque rating at a known position.

torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted.

Helical torsion springs are used primarily in manufacturing applications as components for various motion controls. They come in two basic types, helical (or coil) torsion springs, similar in form to compression or extension springs, and act in a radial direction in applying torque rather than axially to produce tension or compression, and spiral torsion springs, wound as concentric spirals usually from flat, or rectangular, stock. Many different types of torsion springs are available with applications ranging from clocks and watches to motion controls in automatic machinery.

Stainless steel torsion springs made by XULONG SPRING are customized springs according to client’s drawing or sample,and its wire can be round wire or rectangle wire.

● Extension spring:

-designed to operate with a tensile load. An archetypical example is a Slinky, but these are also found in luggage scales and garage door mechanisms.
Extension springs are helically coiled wires designed to provide an opposing force when stretched, also named tension springs. Key specifications include the spring rate, helix type, spring ends type, wire diameter, material, and free and maximum extended lengths.

Extension coil springs are designed to absorb and store energy as well as create a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled. This initial tension can be manipulated to achieve the load requirements of your particular application.

Extension springs are used primarily in manufacturing applications where a variable, opposing force is required between two components. There are many sizes, spring rates, and materials available depending on the holding forces required. The ends are usually formed in the shape of a hook or loop and can also be custom made.

● Hot Roll Spring

-  Hot wound spring, also named hot roll spring, hot coil spring or heavy duty industry spring, lots of descriptions, key point is such springs are coiled in red-hot condition, as its wire diameter is very big. For more information , view this video below:
