Precision Cold Forming and Cold Heading

Miniature Cold Formed Metal Alloy Parts

About Us

With over 65 years’ experience, Deringer-Ney is the expert in this manufacturing process using a wide range of metals including precious metal alloys. We have a broad array of precision cold forming machines for high speed and low cost manufacturing. Every year we expand our primary and secondary processing equipment to better server our customers.  For a detailed article on Cold Forming, read Cold Forming...When CNC Just Doesn't Cut It.



The Cold Heading / Precision Cold Forming Process

The cold heading and cold forming 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.

Cost and Technical Advantages

Precision cold forming can reduce your part cost with savings of 40-60%. Deringer-Ney's processes have many cost benefits. Throughput is high, tooling cost is low, and material yield is almost 100%. Cold forming is a real advantage when the raw material cost is high, as in the case of precious metals. Part consistency is high and metal properties are improved through work hardening. Some materials are not easy to machine but are perfectly suited to cold forming.  




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, we have the ability to hold 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 and Cold Forming for Medical Devices

For medical devices, precision cold forming 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 parts can be formed with metal alloys using 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.  We are ISO 13485 certified.
