What is a torsion spring

Torsion springs tend to be stronger and more durable than extension springs. And though they are more expensive, they last longer, between 15,000 and 20,000 cycles as opposed to 10,000 cycles with extension springs. They also offer greater balance and show more control when moving, not jerking as the door moves.

The reason torsion springs are quieter is because they are located on the wall near the door instead of over the tracks. This leads to less noise transmission when someone opens or closes the door. If you are concerned about accidents, the torsion spring is the way to go.

The manufacturing process of torsion springs usually includes the following steps: First, the appropriate material is selected and processed according to the needs, such as drawing, cutting, polishing, etc. Secondly, according to the design requirements and size requirements, bending and winding are carried out using a torsion spring machine or by hand, so as to form the desired shape and elasticity. Finally, torsion springs are heat treated or surface treated to improve their strength and corrosion resistance, and testing and quality control are carried out.

Selecting the appropriate torsion spring should be selected according to the specific application scenarios and requirements. First, factors such as the required torsional force, elastic deformation and working environment need to be determined. Secondly, the production and cost of torsion springs need to be considered according to factors such as the selected material, size and process. Finally, experimental verification and quality testing are required to ensure that the selected torsion spring meets the requirements.
