Types of Wire Springs & Wire Forms
Wire springs are open-coil helical components designed to resist axial compressive forces. At Atlantic Precision Spring, we manufacture high-quality springs from 0.006″ to 0.187″ using both round and shaped wire.
Primary Spring Configurations
We offer three distinct types of compression and tension springs, each suited for different mechanical requirements:
- Extension Springs: Close-wound with touching coils; designed to resist pulling forces. Common ends include machine hooks and crossover loops.
- Torsion Springs: Designed to resist applied torque. Note that the coil diameter reduces and body length increases during deflection.
- Double Torsion Springs: Features one right-hand and one left-hand wound coil connected to work in parallel for balanced torque.
Critical End Configurations
The way a spring ends determines how it sits in your assembly and how force is distributed. We offer four standard styles:
End Type | Visual Characteristic | Function/Benefit |
Closed End | End coils touch. | Provides a square base without grinding. |
Closed & Ground | Last coil is flat/ground. | Maximum stability and parallel force. |
Open End | No pitch change. | Best for applications with low stability needs. |
Open & Ground | Flat end, no pitch change. | Specialized for specific seating requirements. |
