Industries & Applications FAQs

What industries does Coiling Technologies manufacture springs for?

CTI's published industry list covers actuators, Mil-Spec springs, agriculture, automotive aftermarket, construction, deep sea, material handling, military, mining, oil and gas/petrochemical, playground and recreation equipment, snow plow and snow removal, valves, vehicle suspensions, electric vehicles, pipe hangers and supports, canted coil springs, and medical springs. The customer base includes Fortune 500 companies, the automotive aftermarket, the US Military, and other government agencies. Military suspension springs are a stated specialty, as is large and heavy duty spring work, and the company describes hands-on design and manufacturing experience across every one of those sectors.

Why does the industry a spring serves change how it gets designed?

The application sets the failure mode the design has to defend against, and that drives material before it drives geometry. A downhole valve spring is governed by sulfide stress cracking and sustained temperature. An aerospace actuator spring is governed by fatigue life and weight. A military suspension spring is governed by shock loading and corrosion exposure. The same load and deflection requirement produces three different alloys and three different processing routes. This is why CTI asks for the operating environment alongside load and envelope, rather than quoting from geometry alone. A spring that meets its load and dies in six months has failed.

Which requirements drive material selection across CTI's industries?

Four conditions do most of the work: service temperature, corrosive media, cycle count, and whether load must be held static for long periods. High sustained temperature moves selection toward nickel and cobalt nickel alloys such as Inconel 718, Inconel X-750, MP35N, and Nimonic 90. Chloride or H2S exposure pushes toward nickel alloys and specific stainless grades. High cycle fatigue service favors clean, high strength carbon alloys with shot peening. Static load retention over years makes stress relaxation, not tensile strength, the governing property. Supply those four values and the material conversation gets short.

What spring types does CTI build for these industries?

Compression, extension, torsion, disc, wave, die, drawbar, suspension, and canted coil springs, plus wire forms and pipe hanger components. The site specifically calls out small and large coil springs, heavy duty extension springs, torsion springs, wave springs, and wire forms. Large and heavy duty capability matters most on military suspension, mining, material handling, and electric vehicle work, where wire or bar section runs well past what a general job shop coils. Configuration follows function, so describe how the spring is retained, guided, and loaded in the assembly rather than only naming a type.

Does CTI handle low volume and prototype work, or only production runs?

The company started in 1976 as a fast turnaround, short run spring manufacturer and has since broadened into industry specific work, so short run and prototype jobs are part of the original business rather than an exception to it. Prototyping is one of the in-house services, and the engineering team can develop a full design from performance requirements when no finished drawing exists yet. That continuity matters in industries where a single spring qualifies an entire assembly, because the same facility that builds and documents the prototype builds the production part under the same quality management system.

What certification does Coiling Technologies hold?

CTI is certified to ISO 9001:2015 and is audited regularly against it. That is the certification the company carries. CTI is also a member of the Institute of Spring Technology and the Spring Manufacturers Institute. Products are analyzed before and during production against customer specifications, and the available documentation includes material certifications with chemistry and mechanical property data, dimensional inspection reports with measured values against drawing tolerances, first article inspection reports, load test data, and traceability from the finished spring back to incoming raw material. Industry standards named on your drawing are handled as build requirements.
