Custom Extension Springs

A custom spring is advantageous because it meets your requirements for size, end hook or loop design, return force, material, and finish (if any). Our team will help you achieve a durable and cost-effective solution.

Precision Performance

Our custom-manufactured high-performance extension springs are wound with automated CNC coilers that produce springs with the same tension and diameter every cycle. Rotary wire feed and guide elements keep wire properly aligned and moving smoothly into the machine. We can work with your design or engineer a spring that meets the needs of your specific application, then manufacture prototypes or small or large quantities.

Durability and Strength

Extension springs can be manufactured from many types of metal for use in many applications, including indoor and outdoor operating conditions, heavy- or light-duty use, high-strength applications, and more. We’ll work with you to select the most suitable material for your project and budget.

Cost Efficiency

We use automated, high-precision equipment, which results in springs that are made quickly and with a low error rate. This leads to faster lead times and less wasted material, even with large orders. What’s more, because custom springs are designed to fit a specific application, they can be made in sizes and materials that reduce or simplify maintenance, replacement, and equipment downtime when compared to compromising with a stock spring option.

Our team develops and manufactures custom extension spring solutions for many demanding markets, including:

Aerospace and Defense

Extension springs create the necessary force to control many flight components like rudders, flaps, and ailerons. Lids, doors, and other retracting parts also include extension springs. Since they effectively absorb shock, can be made from materials that resist high impacts and dissipate heat, these springs are found in a range of heavy-duty and mission-critical aerospace and defense applications.

Automotive and Trucking

In automotive applications, extension springs can be used in brake assemblies, door mechanisms, and vehicle suspension systems.

Agriculture and Industrial Equipment

Extension springs provide reliable tensioning in many types of heavy-duty industrial and agricultural equipment, like tractors, harvesting equipment, and balers. These springs help hatches and flaps close and remain secure, and hold extending or telescoping components steady.

Consumer and Commercial Products

Many commercial products incorporate extension springs, including furniture, storm doors, fence gates, fitness equipment, some overhead door systems, and more.

Medical Devices

Precision-engineered extension springs are found in many medical devices and surgical instruments that require tension and controlled movement. Examples include stretchers and adjustable tables, catheters, hand-held instruments, and even inhalers.
