Torsion Spring

For the toughest requirements

Customers from medical and industrial sectors can count on RPK Group as a leading supplier of torsion springs

The helical springs used to apply a torque are commonly called torsion spring. This types are stressed by bending so our engineers must calculate them using different formulae than those used for compression or tension springs (stressed in torsion). We use the Finite Element Simulation to determine the optimum spring shape. The only limit to the complexity of a torsion spring’s shape is the customer’s needs. Our engineers’ expertise and skills and the use of state-of-the-art production technology enable us to meet these unique requirements. The sky is the limit.
