Canted Coil Spring Machine for Precision Sealing and Electrical Contact Springs

A specialized CNC forming solution for producing consistent angled-coil springs used in sealing, conducting, shielding, and mechanical retention applications.

  • Overview
  • Controlled Angled-Coil Formation
  • Recommended Products

Product Details

The Canted Coil Spring Machine is designed for manufacturing canted coil springs whose individual coils are inclined relative to the spring centerline. This distinctive geometry allows the finished spring to provide controlled force over a defined range of compression.

Canted coil springs are commonly used as energizing elements in sealing systems, multi-point electrical contacts, electromagnetic shielding components, and mechanical holding or latching assemblies. The machine coordinates wire feeding and forming movements to control the coil diameter, pitch, cant angle, and overall spring geometry.

Typical Spring Applications

  • Seal-energizing springs
  • Rotary and reciprocating sealing systems
  • Electrical contact springs
  • High-current and multi-point contact assemblies
  • Electromagnetic interference shielding
  • Connector and coupling components
  • Mechanical holding and latching systems
  • Aerospace, automotive, medical, and industrial assemblies

Compatible Materials

The machine can be configured for suitable spring-wire materials according to the product’s mechanical, electrical, corrosion-resistance, and operating-environment requirements. Applicable materials may include stainless steel spring wire, copper-alloy wire, and other qualified spring alloys.

Material compatibility must be confirmed according to the wire properties, dimensions, and required forming geometry.

Information Required for Machine Selection

Please provide:

  • Finished spring drawing or physical sample
  • Wire material and wire diameter
  • Coil inside or outside diameter
  • Spring pitch
  • Required cant angle
  • Free height or radial section dimensions
  • Finished spring length or ring diameter
  • Load or force requirements
  • Dimensional tolerance requirements
  • End-joining or downstream processing requirements
  • Expected production volume

Custom options are available. Contact us to confirm the appropriate machine configuration and tooling.

Controlled Angled-Coil Formation

Unlike a conventional compression spring, a canted coil spring has coils positioned at a designed angle to the spring axis. The machine coordinates feeding and forming movements to establish this geometry, helping maintain consistent coil spacing, inclination, and sectional dimensions throughout production.
