Flat Coiling
Custom flat coiling for precision torque delivery – engineered for performance and reliability.
AMFT designs and manufactures flat spiral, power, and constant force springs that store and release energy in the form of torque. Built for high repeatability and long life, our flat springs are custom‑engineered to meet demanding space, load, and environmental requirements across regulated and high‑performance markets.
Spring Types We Manufacture
AMFT’s flat coiling solutions apply to many industries, including medical, transportation, aerospace, defense, consumer goods, electronics, and power generation.
Power Springs (also called recoil springs or motor springs)
Spiral‑wound flat metal strips engineered to store and release rotational energy efficiently. Ideal for counter‑balance mechanisms.
Constant Force Springs
Deliver near‑constant force across the extension range for smooth, repeatable motion and long life – well‑suited to applications requiring consistent load with minimal hysteresis.
We engineer each spring to meet the environmental, performance, and lifecycle requirements of its specific application.
Applications
Need help optimizing torque curves, deflection limits, or mounting interfaces? Our engineers collaborate early to de‑risk design and accelerate launch.
