Card Springs is a mechanical component designed primarily to provide resistance to applied compression forces while returning to its uncompressed state upon force removal. Its unique structure, often made of flexible material such as metal or plastic, allows for substantial deformation under stress while maintaining structural integrity and functionality. It is widely utilized across various industries, including automotive, electronics, and furniture production due to its versatile applications in shock absorption, vibration dampening, and maintaining contact between surfaces. The design and selection of card springs are highly dependent on their intended use, the environment they will be operating in, and the physical constraints within which they must function. The effectiveness of card springs can be significantly influenced by factors such as material selection, spring geometry, and loading conditions.
