Characters of torsion springs

1. Proportions : They are made of wire diameter between 4 and 14  . Larger ratios require more than average tolerance. Ratios of 3.5 or less often cannot be coiled on automatic spring coiling machines . 
2. Total coils: Torsion springs with less than 3 coils buckle and are difficult to test accurately. When 30 or more coils are used, light loads will not deflect all the coils simultaneously due to the friction with supporting rod.
3. Diameter reduction: The inside diameter reduces during deflection. 
4. Hand: The hand or direction of coiling should be specified for the spring designed, so deflection causes the spring to wind up and have more coils. 
5. Bending Arms: They should be as straight as possible. Bends are difficult to produce and often are made by secondary operations,
