Cold Forming and Cold Heading Process


Cold forming is the process of forging metals at near room temperatures.

In cold forming metal is formed at high speed and high pressure into tool steel or carbide dies. The cold working of the metal increases the hardness, yield, and tensile strengths.

The cold heading process used at Deringer-Ney is similar but specifically refers to the upsetting of a volume of metal into a head like on a nail or screw.


Cold Forming and Cold Heading processes are flexible.  Parts can be hit multiple times while staying in one die ("one die, multiple blow"), or transferred from die to die to progressively form various geometries ("multi-die forming").

Deringer-Ney's Cold Forming consistency is excellent because each part is made in the same die.  Material is used at almost 100% efficiency. There is no scrap as found in machining. Because of the high productivity, the efficiency of material use, and the use of precise dies, cold headed and cold formed parts have significant cost and quality advantages.

The range of possible shapes is rather broad, including heads, threads, steps, knurls, chamfers, grooves, undercuts, and tapers.


Some features that cannot be directly made with Cold Forming or Cold Heading can be added in secondary operations, such as threading, pointing, or rolling.

Typical parts made using cold forming technology include screws, nuts, and bolts, electrical contacts, and rivets. In addition to these "high volume standard" parts, there are many thousands of different custom parts for a diverse set of applications.

Deringer-Ney is a cold forming manufacturing company specializing in small to micro cold formed parts from a variety of alloys including precious and noble metal.
