Regular Compression Springs
Compression springs are designed in order to accumulate strength during the compression so that they can apply it in the opposite direction. This means that, when compressed, the gap between the coils becomes smaller, reducing the size of the spring.
They can be assembled in a parallel or conical shape and are usually produced with cylindrical wires. Other types of wires can also be used, depending on the intended use.
The edges are designed according to the application.
