We manufacture precision components from customer prints using a wide variety of in-house manufacturing capabilities including high speed stamping and machining, wire forming, cold heading and forming, injection molding, and wire EDM. Some of our precision parts are so small, they can only be seen using a microscope.
The leading manufacturer of electrical contacts for diesel-electric locomotives, onboard electrical systems, motor controls and power distribution. The locomotive industry relies on Deringer-Ney's the high-quality electrical contact to keep the locomotives running in any environment. We specialize in contact assemblies produced with materials such as silver nickel and silver graphite as well as compositions of silver or copper blended with tungsten or molybdenum. Our powder metal contact tips are produced in our powder metallurgy department with specialty powder processing and blending equipment.
In our Marshall, North Carolina cold forming facility, we make a wide variety of custom cold formed parts with a special focus on small to micro parts. Many include secondary operations such as rolling, pinching, and drilling. Typical applications are cold formed pins, heat sinks, leads, standoffs, cores, and others. Our in-house tooling department helps control both cost and lead time. Rapid prototypes are available. For a detailed article about cold forming, read Cold Forming...When CNC Just Doesn't Cut It.
Since 1950 we’ve been one of the world’s largest producers of electrical contacts and contact assemblies for electromechanical switches and relays. We make cold headed contact rivets, brazed, stamped, and welded contacts and contact assemblies. Many are assembled using automatic staking or high speed automatic welding processes and we can also offer continuously welded contact tape. Fast prototypes, application assistance and ROHS assistance are all available. More information.
We manufacture precision stampings and microstampings, wireforms, springs, and coils that are used in medical devices, sensors, semiconductor test, and many other technologies. We also make multislide parts, micro and high precision parts. Prototypes are routinely available and we can offer process scrap reclamation for precious metal materials. More information.
We specialize in producing close tolerance, complex CNC Swiss machined and micromachined components for a multitude of medical, dental and other applications. Parts are fabricated from precious metal and titanium and stainless steel alloys. Our in-house precious metal alloy fabrication and scrap reclamation provides an significant economic advantage to our customers. . More information.
Deringer-Ney produces specialty alloys for a variety of demanding applications in the form of wire, strip, ribbon, and rod. We are always inventing new ones. Typical characteristics include high corrosion resistance, biocompatibility, radiopacity, low contact resistance, and in many cases the ability to age harden via heat treatment to high mechanical strength. Our alloy products include Paliney®, Neyoro™, and Paliney® In-Vivo series, plus more. We can fabricate components from these materials utilizing a variety of manufacturing processes including stamping and microstamping, wire forming, machining, and micromachining, cold heading and forming and precision insert molding. We can provide application assistance and can also furnish contract manufacturing services to fabricate complex assemblies to meet your needs. More information.
We provide insert molding of various components, especially precious metal stampings, with tight tolerances and spring force control. These are used as components for sensors and medical devices, fuel level and position sensors, and other parts. For fast support of these molding operations, we maintain a fully capable tool room, an automation department, and a full quality system. More information.
Our Paliney® 7 and H3C alloys are widely used for semiconductor test probes. We manufacture these alloys in a variety of forms – both as raw material and formed parts. Typical shapes include wire and ribbon for straight and buckling beam probes, and continuous or short wire lengths for cantilever probes. These materials are also available in sheet, or we can supply you with a stamped or wireformed part to meet your application. These materials have also been employed as specialty electrodes in semiconductor thin film metallization equipment and as machined spring or “ pogo” pins for electronic testing equipment. More information.
One of our core technologies is the joining of dissimilar metals, especially precious metals. Available processes include automatic welding, in-die staking, brazing, and plasma welding. We offer both high volume (automatic) and low volume (hand) production. Secondary operations are available. All joining operations are supported by in-house tooling departments and quality systems. More information.
Deringer-Ney’s Paliney® alloys are widely used in position sensors, potentiometers, and other low current applications. Typical contacts are bifurcated springs which maintain constant contact resistance in sliding applications. We provide these as discrete parts or as molded assemblies. 100% automatic gram force control with accompanying statistical data compilation is available for our customers. . More information.
Our contract assembly division in Nogales, Sonora, Mexico takes advantage of competitive labor rates coupled with the technical resources of the entire corporation. We assemble products with components produced in any of our manufacturing plants combined with other components provided by you or purchased from outside sources. Typical products are switches, disposable medical test devices, semiconductor test parts, and other devices that require careful process and quality control. More information.
