Definition: Coil compression springs manufactured under a custom design therefore fulfilling a specialty.
Specialty compression springs are made according to the dimensions and loads that the customer requires to be met for their product or device. A spring design with a larger outer diameter than another design, even by one thousandths of an inch, is a completely different compression spring design. This applies to all other spring dimensions. Therefore, there is an infinity of options and rare will be the case when one single spring design will be able to be used for two or more products.
This is what makes a coil spring a specialty compression spring. The customization of physical dimensions like outer diameter or total coils is needed for a compression spring to be able to undergo the loads and travel required for a device to function accordingly. Some devices may need the spring to achieve two working loads which don’t fall into a spring constant. This means that the spring will either need different outer diameters on the coils of its body or variable pitch in between the coils.
