What Is A Compression Spring

Compression springs are open coil helical springs that offer resistance to a compressive force applied. They are usually coiled at a constant diameter but they can also be formed into other coils like conical, concave, convex and many more. These coils are used to hold energy in their compressed state and can be supplied with open or closed end coils.  Under increasing load, the space between coils closes until the spring’s compressed length is reached, when the coils touch.

These springs have tapered ends that are often used in seatbelts. As they are compressed to a shorter height they provide a force to return the spring to its normal height. They are typically made from stainless steel, spring steel and music wire. The potential application for compression springs are limited only by the imagination.

Manufacturing Process

Workers start with rolls of steel cord. The cord diameter varies in size depending on the springs being made. A metal probe detects the correct length for the springs after they are formed. The machine that forms the wire has four rotary shafts called cams. A computer ensures that each spring has the desired specs. The springs are also heated to “relax” the metal this gives them the ability to retain their shape after flexing .

Stock Springs

These can be supplied with open or closed end coils, tapered ends, barrel shaped, or waisted, end ground square, progressive rate or conical. Applications: battery springs, textile springs, electrical appliances, irrigation equipment, lighting and automotive.
