1.Our Services for Cold Formed Copper Parts
Youlin produces standard and custom Youlin® cold formed copper parts for many applications, from automotive and electronics to medical. We offer over 2,300 products including a variety of specialty pins, terminals, rivets and other proprietary value-added parts. With over 10 years of experience in manufacturing cold headed components, we provide custom solutions for all types of fastening needs. We stock materials including carbon and alloy steel, copper, brass and common grades of stainless steel.
Youlin's cold metal forming operations offer significant advantages such as design versatility, high production rates, repeatability and increased strength of components. In addition to multi-station cold heading, we offer secondary services such as plating, painting and heat treating. To support our customers' cost-saving efforts and improve manufacturability, our staff provides expertise and suggestions for appropriate materials, tolerance and part configurations.
2.Advantages of Cold Formed Copper Parts
We choose cold forging over hot forging for copper parts with a number of reasons—since cold formed copper parts require very little or no finishing work, that step of the fabrication process is often dispensable, which saves money. Cold forging is also less susceptible to contamination problems, and the final component features a better overall surface finish. Other benefits of cold forging include:
|
√Easier to impart directional properties √Improved interchangeability √Improved reproducibility √Increased dimensional control √;Handles high stress and high die loads √Produces net shape or near-net shape parts |
▶ Raw material savings of up to 70% ▶ Reduced machining times up to 50% ▶ Improved mechanical properties for material strength and machining due to cold working of the material ▶ Significantly reduced total part costs up to 50% |
3.Application of Cold Formed Copper Parts
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.
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.‘

5.FAQ
Q: What are the challenges of cold formed copper parts?
A: The challenges with cold forming are how does an engineer achieve the superior physical properties and high material cost savings benefits of a cold formed part without spending thousands of dollars on the cold forming punch and die tooling? A standard cold forming process required high volume production in excess of 25,000 pieces in order to absorb the high costs of tooling in order to deliver the dual cold forming benefits of material content savings and faster machining time.
Q: Which type of copper is used for cold forming parts?
A: A considerable proportion of the raw Copper used in industrial applications is supplied in the form of rolled Copper wire.
Q: What is cold drawn copper?
A: Cold-drawn copper wires were made by cold-drawing after hot-rolling tough pitch copper rods which had been pre-heated at 673–973 K. The wires were annealed at 293–673 K to study their annealing properties.
