A compression spring is made of spring wire and exerts a load or force when it is compressed. Compression springs offer resistance to compression and are constructed to oppose the
axial compression. A compression spring is defined in diameter, wire thickness, free length and number of coils. It is also very important to define whether or not the edges are plain or if they are
grounded or not.
If an existing spring should be stronger, weaker, longer or just smaller, it can be adjusted in accordance with the design. In addition, the spring should be monitored to establish whether it is suitable for the desired applications and if the desired life expectancy is actually achievable.
