FlexForce™ Slant Coil Springs

FlexForce Springs from Advanced EMC Technologies are a unique slant (or canted coil) spring. They were originally designed as an energizer for Teflon seals, and provided a predictable and very flat load curve in the compressed position for seal applications that required highly critical friction and torque specifications.

In the last 20 years, this unique spring design has found applications in connecting two components  — “latching and holding” — where the insertion and removal force can be designed with great accuracy.

In addition to mechanical Locking or holding applications, connecting for optimum electrical conductivity is possible due to the small coil size and the number of independent coils. In regard to EMI/RFI shielding applications, the slant coil spring offers an economical design option that can reduce radiated and conducted interference to prevent premature failure in electrical devices. The springs are available in 300 Series Stainless, Hastelloy and copper alloys to meet numerous environmental conditions or specific conductivity or shielding requirements.

We offer our Canted or Slant Coil FlexForce springs in gold, silver and nickel plating for use in electronic and semiconductor applications.
