Torsion springs, crucial in industrial settings, are designed to exert rotational force or torque when twisted. Typically 8mm in size and silver in color with a polished surface finish for corrosion resistance and aesthetic appeal, these springs are made from various materials suited to specific applications. Their unique design allows for efficient energy storage and release, making them ideal for mechanisms requiring rotational movement, such as door hinges and clockwork mechanisms. Torsion springs offer advantages including precise torque control, compact size, and durability, contributing to the smooth operation and longevity of industrial machinery and mechanical systems.
