Industrial Coils for Electric Automotives


Electric vehicles are no longer an emerging market dominated by Tesla. Electric Vehicles are here to stay and are being produced by automotive giants such as Audi, BMW, Changan, Chrysler, Ford, GM, Mercedes, Nissan, SAIC Motor, Tata, Toyota, and Volkswagen.

With more Electric Vehicles being built and delivered every day, Coiling Technologies, Inc., is well suited to support the Electric Vehicles market. We can design and manufacture customized springs ideal for use in all makes and models of electric and alternative-fuel vehicles whether it is for passenger or commercial vehicles.

Electric Vehicles have unique load and weight distribution requirements over a typical Internal Combustion Engine (ICE) vehicle. The added weight due to batteries, the location of the electrical drive motors and components, and fuel storage cells, can significantly alter the ride and handling characteristics of the vehicle. Electric Vehicles' typical GVW is 15 – 25% higher than a conventional ICE vehicle. This means Electric Vehicles require a suspension that has a higher load rating capacity than a standard configuration ICE vehicle. This makes Coiling Technologies an ideal fit when larger suspension springs are required for an EV application.

Coiling Technologies, Inc., has more than 3 decades of experience in manufacturing automotive and truck suspension springs and suspensions for military vehicles such as up-armor springs for the HMMWV (Hummer) program. Where the HMMWV GVWR increased by more than 50% due to the additional armoring. Our technical team has a background in vehicle dynamics and can provide the necessary tools in assisting our customers in creating a custom spring solution for their specific vehicle application. CTI has the ability to reproduce or reverse engineer a spring from your sample or work with the customers' design specifications.


Providing the right product

Coiling Technologies, Inc., manufactures customized springs, suspension springs, extension springs, wave springs and torsion springs for the ever-evolving electric vehicle market.

Our skillfully designed, expertly engineered, and rigidly tested springs can be deployed in a wide range of applications to support the EV market.

Our capabilities include creating customized suspension springs, compression springs, extension springs and torsion springs for:

  • Suspension systems
  • Armoring Springs
  • Lowering Springs
  • Lifting Springs
  • Racing Springs
  • Trip Springs
  • Valve Springs

The most common suspension spring material is chrome silicon alloy (CrSi). CTI has the capacity to cold coil high-strength chrome silicon suspension grade wire up to 0.984” (25 mm) on their Simco 6250 automatic coiler. We also have the capacity to cold coil up 2.50” (63.5 mm) diameter bar material in various alloys including:

We stock all these alloys and can support low or high-volume manufacturing to meet our customer’s needs.
