Compression Springs

Compression SpringsWe offer custom compression springs made from a range of materials. In-house CNC spring coilers are used to manufacture precision compression springs with close tolerance spring loads, making them ideal for a multitude of critical applications. From medical devices to mining and drilling equipment, there is a range of industries that rely on these versatile springs. Different spring configurations such as hourglass (concave), barrel (convex), and conical compression springs can be manufactured with our CNC coilers.

Available Sizes

Springs are available in wire sizes ranging from 0.005” to 0.250″. Open-ended, close-ended, and combination-ended configurations are available. End grinding services are offered for compression springs with a minimum wire size of 0.018” and outer diameter from 0.060” to 3”. Customers can also choose from our wide range of secondary services, such as passivation of stainless steel, plating, and heat treatment for stress relieving.

Custom Spring Design Services

Our in-house engineering and design department can provide design assistance as well as verify existing spring designs. We accept compression spring designs in a number of file formats, including DWF, DWG, DXF, FBX, JPG, PRT, SAT, TIF, STP, and PDF. Prototype development services are also offered to our customers for product evaluation prior to actual production.

Frequently Asked Questions About Compression Springs

Compression springs are used in a wide range of applications, including automotive, aerospace, medical devices, and industrial equipment. They provide resistance to a compressive force and are commonly used to store energy or absorb shock.

Compression springs can be manufactured from Beryllium Copper, Chrome Silicon, Chrome Vanadium, Elgiloy, Hard Drawn Wire, Hastelloy, Inconel, Monel, MP35N, Music Wire, Nitinol, Oil Tempered, Phosphor Bronze, Stainless Steel (17-7 SS, 302 SS, 304 SS, 316 SS, & 316L SS), and Titanium. The material used will depend on the specific application and the required performance characteristics of the spring.

There are several factors that should be considered when designing a compression spring, including the spring’s intended use, the desired spring rate, the material used, the amount of force required, and the available space for the spring.

The spring rate is the amount of force required to compress the spring by a certain amount. It is typically measured in pounds per inch (lbs/in) or newtons per millimeter (N/mm). Learn more about calculating spring rate.

The maximum load will depend on several factors, including the material used, the wire diameter, and the spring’s dimensions. It is important to carefully consider the maximum load when designing a compression spring to ensure that it will function properly and safely.

The manufacturing process typically involves coiling a wire around a mandrel, heat treating the spring to improve its strength and durability, and then grinding the ends to ensure a flat and even surface. Learn more about how compression springs are manufactured.

Yes, we can manufacture custom springs to meet specific requirements for load capacity, spring rate, and other performance characteristics. Our custom springs are manufactured using specialized equipment and techniques.

The lead time for manufacturing compression springs will depend on the complexity of the spring, the quantity required, and other factors. We can manufacture most compression springs within 4-6 weeks.

Our Quality Management System is certified by ISO 9001:2015. We have the ability to provide specialized reports upon request, including First Article, PPAP inspections, material certificates, and Certificates of Conformance.
