Ace Wire Spring & Form designs and manufactures custom compression springs to the exact requirements of our customers’ needs. Compression springs are open coiled helical springs that resist a compressive force applied axially. They may be tapered, conical, cylindrical, convex or concave in shape. The changing of the ends, direction of the helix, material and finish allows compression springs to meet a variety of specially designed needs.
A type of wire spring used in everything from appliances to motorized equipment, motors, and more. Compression is compressed by a load acting upon them or their ends are compressed, the design of the wire tries to return it back to the original shape thus pushing the load back. They are designed and used to resist applied compressive forces or to store energy in the push mode. Typically they are cylindrical helical made out round wire. However they can be made conical, oval, barrel or virtually any other shape. The wire can also be round, square or rectangular. This is the most common configuration and are found in many applications such as automotive, aerospace and consumer goods.
One can control the actions of compression springs by how they are designed. The diameter of the coil, the number of coils, the style of the ends even the length and diameter and shape of the wire can all make different designs. This is why it is so important to have all the right dimensions when ordering so its performance will meet the needs of the application.
Ace has been a custom compression spring manufacturer and designer since 1939 and has helped thousands of companies fill a need for the job but also offer a variety of design and manufacturing services. We are large enough to provide capacity and repeatability yet small enough to still offer custom design and production runs for special requirements.
Whether you need help in specifying or designing, or just looking for an American manufacturer, Ace would be happy to demonstrate our capabilities and quality for you.

Trivia Questions and Answers
Q) What governs the dimensional limits of a spring? A) In designing custom compression springs, the space allotted governs the dimensional limits with regard to allowable solid height and outside and inside diameters. These dimensional limits, together with the load and deflection requirements, determine the stress level.
Q) What is an advantage Conical Compression Springs offer? A) Conical Compression offers the advantage of a reduced solid height compared to straight compression springs, especially when capable of "telescoping." Conical Compression Springs are cone shaped springs designed to provide a near constant spring rate and a solid height lower than a normal spring. Each features a variable pitch to achieve the constant spring rate and coils which nest during deflection to provide a solid height approximately equal to two wire diameters.
Q) What is the most common and recognizable spring type? A) Compression is typically the most common and recognizable type. They come in a huge range
of different styles, which adds to the fact that they are considered as being universal and so readily available.
