Cold forging - A cold forgings manufacturer and supplier from China The history of cold forging could be traced back to more than 5000 years ago, the first human forging method is cold forging. In 20th century, with the development of hot forging, cold forging was mainly applied in some small forgings. However, cold forging process has become the first choice of many parts in recent years because of its smooth surface. SK forging group has nearly thirty years experience in cold forging. SK provided customers with high quality cold forging products.
What is cold forging? Cold forging is a forging process that forged a metal below the recrystallization temperature. Cold forging usually refers to the forging at room temperature. The temperature is higher than room temperature, but less than the recrystallization temperature known as the warm forging. Features of cold forging 1. Cold forgings have good surface quality and high precision size. Cold forging products can reduce some machining and cutting process. Cold forging of metal could improve the strength of parts. 3. The size of cold forging products is relatively small. At beginning, most cold forgings are screws, bolts, nuts and other products.
What materials were used in cold forging? Most of Cold forging materials are smaller deformation resistance and good plastic at room temperature such as aluminum alloy, copper and some alloys, low carbon steel, medium carbon steel, low alloy structural steel. Applications of cold forgings Cold forging parts become more complicated than before. The cold forgings have developed to different shapes from the beginning of the stepped shaft, screw and nut. Cold forging has better precision than hot forging. For example, the production of the barrel adopted the cold forging process because of its high accuracy and stiffness.

Useful Guides of Cold Forging 1. FIA useful guide- Cold Forging process operations FIA introduced the cold forging process operation through three pictures. You may find more information about cold forging in the official website of FIA. 2. Efunda article about cold forging Cold Forging is a cold working process where the material is squeezed into a die and the finished parts assume the shape of the die. This process is also known as Cold Heading. 3.Turn up heat on cold forging Metaldyne was cold forging shafts in a traditional fashion. A billet was cut, lubricated with phosphate and soap, and forged in a press. Then the workpiece was transferred to another press and the process was repeated. 4. Flexible tools for cold forging The advantages of cold forging micro-components are the same as for conventional cold forging, namely the high production rate and the low material waste. To achieve this, a flexible tool system for cold forging of micro-components has been developed. When transferring the technique of cold forging from macro- to micro-scale. |
