How is quality control managed?

We perform 100% inspection including visual and function tests, along with hardness, elasticity, and fatigue tests to ensure performance requirements are met.

What is the working principle of the spiral spring?

As the arbor rotates, the spring winds up storing energy, which is released as mechanical torque through the drum when the spring unwinds.
