Many different types of Springs, each designed for a specific use

Torsion Springs are helical springs that exert rotary force and work by twisting along their axis. Often, they are tightly wound so each coil contacts the next; when twisted, they exert a torque in the opposite direction, proportional to the amount they are twisted. 

The Compression Spring is among the most basic and widely recognized types of spring. Its simplicity is its strength—it compresses and, when compressed, exerts force in opposite directions while trying to return to its original spring shape, a testament to its reliability.

Conical Springs are a type of tapered compression spring with a unique cone shape. They have a larger diameter that funnel down to a smaller diameter.

Barrel Springs start at a smaller diameter, increase in diameter at the center, and then reduce diameter again to match the starting diameter size of the spring.

Hourglass Springs are inverted barrel springs and can be designed so that each coil fits wholly or partially into an adjacent coil. Both barrel and hourglass springs are used in applications that require a low solid height, increased lateral stability, or resistance to surging. 

Differences Between Single-Point and Dual-Point Spring Coilers

FENN-Torin-Coilers_Dffrerences-Between

Either type of coiling machine can make quality springs so it comes down to understanding your needs. Some things to consider are the type of springs in your workload and where you need capacity. If the requirement is for only compression springs, the dual point coiler helps to eliminate the risks associated with marking the ID of the coil. If you need to make a mixture of springs and want to change quickly from coil springs to torsion springs with some bent ends, a single point machine may offer more versatility. Another important consideration is what your production team is most comfortable with. When making springs, both types of machines offer different strengths. A blending of the two technologies is typical in most industries. We don’t believe that one technology will completely displace the other. For example, a shop may want to use dual-point machines for compression springs but may want to use single points for extension or torsion springs.

Constant Force Coilers

Since the 1950s, Torin has been supplying Constant Force Coilers, specially designed coiling machines for manufacturing constant force springs. FENN has developed the CF-Series into reliable machines capable of making top-quality constant force springs.

As part of FENN’s unique design, the same set of feed rolls can be used for the entire range of the machine – there is no need to change rolls for varying thicknesses of material. FENN offers the complete package for your constant force coiling operation – machine, press and guiding, exit chutes, payoffs, and ovens.
