(Counterbalance Springs / Constant Force Springs/spiral springs)

In response to customer demand, Dynamic spring Works, in 2009 expanded the product line to include the production of counterbalance springs - also known as regulator springs, spiral springs and/or constant force springs. These springs are a form of a torsion spring, made of rectangular material. This spring type is commonly used in automotive seating and other highly demanding applications. As a result of these high performance requirements, the torque delivered per revolution is linear for the first 360 degrees. These springs are required to apply constant force until the 360 degree point of rotation as they store rotational energy when turned about the center shaft.
