Precision Small Wire Compression Spring 0.15mm Dia for Sensors Custom
Springs inside sensors demand exceptional force accuracy and dimensional consistency. We specialize in precision small springs with wire diameter 0.1-0.25mm, achieving spring rate tolerance within ±5%. Ideal for pressure sensors, displacement sensors, and micro-force balance mechanisms. 100% CCD optical inspection ensures every spring is dimensionally perfect. Small batch from 100 pieces, 48hr sampling.
Compression Spring Product Description
In sensor design, springs often act as force-displacement conversion or preload elements. Force deviation directly impacts sensor accuracy. For example, if a pressure sensor's spring force varies by more than 5%, output signal nonlinearity may result. Tingfeng Hardware understands the demanding requirements of sensor customers. We use Japanese high-precision spring formers with real-time wire diameter measurement and force monitoring, ensuring consistent coil count, OD, and free length for small-wire springs.
We have developed a dedicated micro-force test system for springs with full scale ≤5N, achieving ±0.01N accuracy. Spring rate test reports are provided per batch. For extremely fine wire (0.1mm), we recommend closed not ground design, as grinding may introduce burrs. Stress-relief annealing is available upon request. 15 years of precision manufacturing experience, helping your sensors achieve high reliability.
