Torque Control
Torsion springs engineered for torque-angle behavior and arm fit accuracy.
Torsion springs generate restoring torque through angular displacement. Feima supports single and double torsion springs, custom arms, installation-angle control and torque test requirements for international buyers.
OEM / ODM made-to-drawing supply
Product Overview
Controlled rotation force for hinges, covers, levers and reset mechanisms.
Torsion spring performance depends heavily on arm geometry, coil direction, mandrel fit and working angle. We review these details before production so the part fits the mechanism instead of only matching a drawing on paper.
Common applications
Automotive interior mechanisms
Hinges and covers
Electronic switches
Locks and safety devices
Appliance doors
