What is a Coil Spring
Three common types of coil spring designs are compression, extension, and torsion. Types of Coil Springs A compression spring is an elastic coil, made of spring steel, or another non-ferrous metal, and is very efficient at building up energy when loaded. As the name suggests, the main characteristic of compression coil springs is to absorb
