Reference only. This records a previous custom configuration, not a fixed stock size.
ENGINEERED FOR YOUR APPLICATION
Built around the mechanism — not selected from a fixed catalogue.
For a new project, Zongda reviews the operating load, available space, rotation range, shaft and housing interfaces, working environment and expected cycle life.
The final spring geometry, force profile and end connection are developed around those requirements, from prototype validation through volume production.
CUSTOM CONFIGURATION
Four variables we engineer together.
01
Force Profile
Required force, force consistency and operating range are developed around the mechanism.
02
Travel & Strip Size
Working travel, strip thickness, width and developed length are matched to the available envelope.
03
Coil & Mounting Ends
Coil diameter, drum interface, attachment method and end geometry are engineered for the assembly.
04
Material & Cycle Life
Material is selected for force duty, fatigue life, corrosion exposure and the working environment.

Even if every parameter is not yet confirmed, our team can review the known force, travel, available space, mounting interface and operating environment with you.
