Micro Spring/微彈簧

Micro Spring/微彈簧

Micro Springs are miniature precision springs, typically with wire diameters smaller than 0.2 mm, designed for compact mechanisms and high-precision devices. These springs provide stable elasticity or conductivity within limited spaces and are widely used in medical instruments, precision electronics, sensors, camera lenses, communication devices, and micro switches.

Micro springs can be made as compression, extension, or torsion types, customized to meet specific application needs. Their production requires high-precision coiling and inspection equipment to ensure dimensional accuracy, surface quality, and consistent spring performance.

Common materials include stainless steel, phosphor bronze, and specialty alloys such as Inconel or Elgiloy, with optional heat treatment or surface plating to enhance conductivity, corrosion resistance, and durability.
