Extension Spring Manufacturing
Extension springs store energy and resist pulling forces by elongating under load and returning to their original length. Typically made of stainless steel for durability and corrosion resistance, they’re vital in mechanical systems.
Custom and Stock Extension Spring Manufacturing in Any Configuration
If you need extension springs, Western Spring Manufacturing has you covered.
Our engineers are trained to use cutting-edge techniques to craft extension springs for exceptional performance, durability, reliability, and cost-effectiveness. We also offer a wide range of extension spring sizes, and materials, allowing us to tailor our products to the unique needs of our customers.
- Medical:
Extension springs are used in medical equipment like surgical instruments and devices where controlled extension and retraction are essential. - Aerospace:
Extension springs are critical in the aerospace industry and used in such particular applications as seats, landing gear, cargo systems, and doors. - Construction:
Extension springs are designed for use in various construction applications, including scaffolding and temporary supports, where controlled extension is required. - Electronics and Electrical Devices:
Extension springs can be found in electronics, such as switches, connectors, and wire management systems, providing tension and control.
Whatever wire and wire diameter you need, we can provide it and if it isn’t in our catalog, we can custom-make your springs to your specifications.

Extension Spring Testing
We Rigorously Test and Measure Your Extension Springs to Meet Every Parameter You Require
- Material Testing:
We monitor every lot of wire material that is submitted for testing and prototyping to ensure the highest quality product. - Dimensional Accuracy:
This involves measuring critical dimensions of the extension spring, such as wire diameter, outer diameter, length, and the number of active coils. This ensures that the spring conforms to your specified design requirements. - Load Testing:
This test involves subjecting the extension spring to various loads to verify that it can extend and retract without any deformation or failure. The load should be applied gradually to prevent sudden overloading. - Elasticity and Stress Testing:
This test evaluates how well the spring returns to its original shape after being stretched. It measures factors like modulus of elasticity and yield strength to ensure the spring can handle the expected loads. - Fatigue Testing:
Extension springs are often subjected to repeated cycles of loading and unloading. Fatigue testing simulates these conditions to ensure the spring can withstand the anticipated number of cycles without failure. - Load Testing:
This involves applying a load to the spring and measuring the corresponding deflection. This helps characterize the spring’s behavior under different loads. - Visual Inspection:
A visual examination of the spring is crucial to identify any surface defects, such as cracks, pitting, or other anomalies.

We needed a spring for an old hydraulic valve and we couldn’t find anything from any hydraulic shop. I called Western Spring and talked to Alex and he said bring it In and we will see what we can do. We had a production line down so this was a hot part. Got in and Alex had pulled some comparable springs and we found one that worked. If it wasn’t for Alex and Western Spring we would still be line down. Thanks for all the help and the great customer service, you guys run a great shop.
