The Cold Heading/Cold Forming Process

The cold heading process has numerous advantages including low manufacturing cost, part-to-part consistency, efficient material usage, and good surface quality.

At Deringer-Ney, we specialize in custom forming of small and micro parts, made from a variety of metals including copper, stainless steel, silver, gold, palladium, platinum, nickel, tantalum and Kovar. We also manufacture electrical contacts, contact rivets, and cold headed rivets. We supply prodcuts to a wide range of manufacturing industries including appliance, medical devices, semiconductor test, aerospace and automotive to name a few.

Cold forming vs machining.

Cost and Technical Advantages

Cold Forming can reduce your part cost with common savings of 40-60%.

Deringer-Ney's processes have several cost benefit., Manufacturing speeds are high especially as compared to machining, tooling cost is low, and material yield is almost 100%.

The high material yield is a real advantage when the raw material cost is high, such as for precious metals. Cold formed part consistency is high. Metal properties are improved through strain hardening. Parts are smooth and mostly burr-free.  

Some materials are not easy to machine but are well suited to cold heading.  These include materials that do not readily form chips, like nickel and gold.  Since with cold heading no chip formation is required, poor machinability is not a problem.

Tolerances and Technical Data

This technology can produce consistent parts at rates of thousands per hour. Because the parts are "cold forged" in a closed die, it is possible to hold relatively tight tolerances.

With over 60 years in the cold forming business, Deringer-Ney has ample data about this manufacturing process. To learn more, go to cold forming tolerances and technical data.

Bimetal and Solid Electrical Contacts

We produce billions of bimetal and solid electrical contact rivets using this forming process.

Many different contact materials are available, including silver, copper, silver-tin oxide, silver-nickel, and silver-cadmium oxide. We routinely provide ROHS assistance.

We also produce millions of parts made by automatic welding and automatic staking contacts.

Many medical devices contain cold formed parts.

Cold Heading for Medical Devices

For medical devices,  thisforming is often an enabling technology. Many parts are designed from metals which are very difficult to machine. When this occurs, cold heading and cold forming are often the best technologies to make the parts. Many biomedical alloys can be formed like gold, platinum, tantalum, and nickel.

High material yields and manufacturing speeds help keep cost low.

Deringer-Ney also offers specialized alloys for implantable or invasive medical devices
