Compression spring
Compression spring
Compression spring is a spring that exerts force when the spring is compressed. The spring is also known as pressure spring. The force of the compression spring is defined by the spring constant, i.e. the required load for each compressed millimetre.
The force of the spring comes from its physical dimensions:
- wire diameter
- frame diameter
- total length
- number of coils.
A typical compression spring is shaped like a cylinder but they can also be manufactured in other shapes, such as barrel, hourglass or cone, depending on what the customer needs. The ends of the spring can be ground even to make the spring stand upright. If grounding is not needed, the end coil will be attached to the previous coil or the ends are left open depending on the spring pitch.
Compression springs with d0.3-d20.0 mm spring wires
By changing the physical proportions of the spring, we can influence the spring’s force, movement and number of use cycles. Our design service is happy to help you design your springs and calculate the appropriate forces. A spring that is tailored for its exact purpose is a functional and safe piece that saves expenses. Jousivesa manufactures compressions springs with d0.3-d20.0 mm spring wires.
Whether you need one speciality spring or springs in bulk, our modern machinery and motivated staff are always ready to help!

Material and surface treatment
All compression springs are made from spring steel. The type of spring steel is determined by the intended purpose. When choosing materials, the external operating conditions must be taken into account. This includes factors such as humidity, temperature, and the load targeted at the spring. At Jousivesa, we only use high-quality spring steel.
Compression springs can go through surface treatment to achieve better corrosion resistance or for visual reasons. Some of the most common surface treatment options are zinc plating, powder coating and shot peening.

Number of coils in the spring
The total number of coils (ig) is calculated from one end of the wire to the other, and the number of coils is not always even.
