A torsion spring is a spring that works by twisting its end along its axis; That is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted.
Materials of torsion springs
Torsion springs can be manufactured from a variety of materials, common materials include Spring steel, carbon steel, stainless steel(301/316/17-7PH), piano wire, nickel alloys, copper alloys, and so on.
Application of torsion springs
Mechanical equipment: used to control the movement, reset and positioning of parts.
Toys and models: provide flexibility and movement, increase interest.
Electrical products: reset and operation of switches, buttons, etc.
Door and window hardware: realize the automatic closing and positioning of doors and windows.
Measuring instrument: help accurate measurement and positioning.
Office equipment: in some copiers, printers play a specific function.
Auto parts: such as the reset of the dashboard pointer.
Industrial Automation: Control and drive components in automated production lines.
Household items: such as some household items with elastic function.
Medical Devices: Operation and control of specific medical devices.
