Torsion springs are often subjected to repeated rotational movements, such as in valve systems, lifting mechanisms, and locking devices. Our lifetime tests simulate realistic usage conditions under which the torsion spring is subjected to thousands or even millions of cycles. This allows us to detect fatigue, wear, loss of resilience, and other failure mechanisms early on. These tests are especially valuable in sectors where reliability and safety are crucial, such as in medical equipment, automotive, and aerospace applications. By gaining early insight into long-term performance, downtime and repair costs can be significantly reduced.
