Virtually all of our manufactured torsion springs are customised to specific customer requirements, meaning that they are not found anywhere else and unique to your design. Also, the speed of production for torsion springs is one of the fastest of all our special products as this type of spring only requires one type of machine for production so there is no finishing involved. We can produce torsion springs from 0.3mm to 26mm thick wire, and have no limits on the material used, though radius limitations should be considered for the purpose of use of exclusive materials.
