• Key Features:

  Due to the shape when a prestressed power spring is released, it assumes an S shape, while power spring assumes a spiral shape. However, prestressed power springs can store 25% ~ 55% greater energy than power springs. It also has higher turns than power spring when their size are the same.

  1. Pre-stressed power springs are pre-stressed to produce a flatter torque gradient than conventional power springs.
  2. Pre-stressed power spring can store 25% ~ 55% greater energy than power springs.
  3. Pre-stressed power spring also has higher turns than power spring when their sizes are the same.

• Key Applications:

  Power springs are mainly used in clock, spring motors for toys, timers, as well as in retractor mechanisms for electrical cords, compressor pipes and seat belts.
