A brief guide to the design and use of compression springs.
Compression springs are among the most common types of spring available due to their energy storing properties. When the coil is pressed, it stores the energy until it is released: ideal for everything from trampolines to mattresses, and shock absorbers. Whereas an extension spring is designed to pull things together; compression springs are designed to keep things apart.
In order to make the spring dependably solid, the pitch, or 'distance between coils' must be kept the same throughout the wire. This can be a problem if done manually or using a lathe. Our specialist machinery at European Springs has no trouble keeping the pitch consistent, and we can specify the length of the pitch in the design process.
What Are They Used For?
Because compression springs are so versatile, they are used in a whole host of industries ranging from automotive, electronics, medical equipment, and commercial/industrial markets.
When it comes to bigger industrial machines, compression coils are often required for parts. You can see in the below video how we manage much thicker alloys and turn them into very powerful compression coils:
Compression coils are fantastic devices with a variety of uses, though a great number of factors must be considered before construction, for example; spring rate, wire diameter, number of active coils, solid height, and the stress level.
So the next time you are pushing a Slinky down the stairs, you can explain exactly how it transfers kinetic energy all the way down.
