The power spring is formed by winding a steel strip on a mandrel, thereby creating a compact power source with mechanical functions such as driving power, tensioning and loading, retrieval and automatic retraction.

Ming Tai Industrial Co., Ltd., one of the world's leading manufacturers of steel strip springs, has developed a wide range of power springs for many interesting applications. Let us give some example to the industrial engineers for reference.

The power spring can store the driving force. When applied to a pen-type drug injector, the power spring can accurately generate a driving force that matches the sliding force of a conventional syringe needle, thereby completely injecting the drug.

When it comes position movement and high adjustment of machine and appliance, precise positioning performance and ease of operating are required at first priority. Ming Tai’s power spring employed in Draw-wire Encoder for position movement application have gain excellent performance.

Power spring features retractable function, it is ideal component to apply on gravity dissipater for fall arrestor.  It is installed between the wire harness and the anchoring point. The function of the power spring is to keep the steel cable forever tightened, in order to avoid winding the steel cable to other components, and causing the fall arrest function to fail.

Power springs embedded in seat belt of automotive function the same as fall arrestor. It keeps seat belt retrieval and retraction smoothly, not to intertwine itself to ensure passenger safety.

There are a number of different power spring design possibilities for a given applications, we strongly suggest you contact us for more detail information in the design phase. Even it is just a simple idea; Ming-Tai will develop optimized solution of power springs to fulfill your product innovation.
