Custom Extension Springs

Custom Extension Spring Manufacturing Capabilities from Argo

Argo’s custom extension springs start with high-quality materials and precision CNC forming technology. We can create springs with virtually any tension, length, and end type to produce the required return force.

Material Selection

We work with many high-performance, durable materials to ensure each spring performs as intended under mechanical and environmental stresses. Material options include:

  • Carbon steel
  • Inconel
  • Stainless steel
  • Exotic metals

Manufacturing Process and Spring Options

Argo Spring uses advanced CNC automatic coilers for efficient, precision shaping and minimal variation from spring to spring. We include appropriate stress relief procedures and heat treatment to enhance material durability and fatigue resistance.

Hook and loop ends are available for all extension springs, including machine, extended, over-center, and swivel hook ends, and full or double twisted loop ends.

We offer many plating and coating options, including:

  • Black oxide coating
  • Powder coating
  • Cadmium plating
  • Silver, gold, and other precious metal plating
  • Tin plating
  • Zinc plating

Quality Control & Certifications

Argo Spring maintains the highest quality standards and procedures. These include first-article inspection, load testing, optical comparators, Rockwell testing, and statistical process control. We are ISO 9001:2015, AS9100D, and MIL-1-45208A-certified.

Benefits of 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.

Common Applications of Custom Extension Springs

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.
