What is Compression spring?

Compression Springs are open-coil helical springs wound or created to oppose compression along the axis of wind. Helical Compression is the most typical steel springtime arrangement. These coil springs can function individually, though commonly assembled over a guide rod or equipped inside an opening.

Typical Compression Spring Design Terms

According to the Spring Manufacturers Institute Handbook of Spring Design, commonly used compression spring terminology includes the following:

Wire diameter (d)
Outside Diameter (O.D)
Inside Diameter (ID)
D coil diameter =Outside Diameter. (O.D. + I.D.)/2 or O.D. - d 
Free Length = The total length of a compression spring when it is unloaded.
Pitch (P )= the distance between the wire centers in adjacent active coils. It is best practice to specify the number of active coils rather than the pitch.
Compression Spring Materials
Zihuoli Spring custom compression springs from a variety of materials. Music wire, hard drawn, stainless steel (type 302, type 316), oil tempered, chrome silicon, and phosphor bronze are the most common material types for compression springs. We also make compression springs out of more exotic materials like Inconel, Monel, Beryllium Copper, and others.
In order to provide our customers with the shortest lead times possible, we stock several of these material types in various diameters.
Compression spring materials that are commonly used include:
•      Carbon Steel
•      Stainless steels
•      Alloy steel
•      Copper Base Alloy
•      Nickel Base Alloy
•      Cobalt-Nickel
•      Titanium

Zihuoli Springs Capability for Different Compression Spring Body Shapes
There are four different body designs for compression springs are produced by Zihuoli Spring.

1. straight cylindrical compression spring
2. Conical or tapered compression springs, 
3. barrel compression springs, 
4. hourglass compression springs,

 
Zihuoli Spring is a leading manufacturer of Custom Spring. We manufacture various springs related tests and test reports: 1. Spring strength test: we have a variety of automatic spring testing machines, which can test the force, tensile strength, bending strength, compressive strength, elastic modulus, fracture elongation, yield strength and other data of spring products. The load accuracy can reach ± 0.01%, which reach GB and international standards such as ISO, JIS, ASTM and din. Salt spray test can be carried out by Salt spray test machine. We will test the corrosion resistance after the surface treatment, such as coating, electroplating, organic and inorganic film, anode treatment, rust proof oil and other anti-corrosion treatment so as to establish the quality of the product.
