Midstate Spring has been manufacturing precision springs and wire forms since 1939. While our technology has changed, our commitment to superior quality and service remains. We have learned lessons from our past, but we are not stuck in it. If you are a manufacturer, springs and wire forms are certainly not the most glamorous components of your product, but they are necessary. At Midstate Spring, we are committed to being your Invisible Partner. In these busy times, we will be there for you when you need responsive service or engineering assistance, but otherwise we will be invisible: our springs will be correct and on-time.

Midstate's business model focuses on continually investing in new manufacturing technology. As a result, we are constantly finding new ways to automate production and remove costly manual operations. While our competition is using old manual machines that we have thrown out, we are automating more and more processes, enabling us to tighten our tolerances and increase our run times.

Compression Springs:
Midstate manufactures compression springs in various shapes including straight, conical, barrel, hourglass, and magazine. Our standard grinding tolerance is square to within 3 degrees, but we are capable of production grinding within .5 degrees when needed.

Extension Springs:
Extension springs are available with various hooks and loops including English, Extended, German, and several specialty ends.

Torsion Springs:
Our CNC machines and highly-trained technicians allow us to produce most torsion and double torsion springs without costly secondary operations.

Wire Forms and Retaining Rings:
Whatever your engineering imagination creates for your manufacturing solution, we can make.

We inventory a variety of the following materials, and can work with many more: High Carbon Steels, Copper Alloys, Stainless Steels, Alloy Steels, and Low Carbon. We provide the following plating and finishing processes: Black Oxide, Cadmium, Chrome, Copper, E-Coat, Electroless Nickel, Electropolish, Grinding, Nickel, Passivation, Powder Coat, Shot Blast, Stress Relief (Heat Treat), Tin, Zinc, and Zinc and Chromate.
