Advantages and Characteristics of Cold Forged Fasteners

What is Cold Forging?

Cold forging, also known as cold volumetric forming, is a manufacturing process and method of machining. Similar to the stamping process, cold forging is constituted by three elements: material, die, and equipment. However, in stamping, the material used is mainly sheet metal, while in cold forging, the material is primarily round bar stock.

Cold forging refers to various volumetric forming processes performed below the recrystallization temperature of the metal. From the theory of metallurgy, it is known that the recrystallization temperature of various metal materials differs. However, for metals like iron, copper, and aluminum, forming processes at room temperature can be termed as cold forging.

The cold forging process is a precision plastic forming technology that has unmatched advantages over machining methods. These advantages include good mechanical properties of the products, high productivity, and high material utilization rates. It is particularly suitable for mass production and can be used as a method to produce final products, having widespread applications in industries such as transportation, aerospace, and machinery.

Advantages of Cold Forged Fasteners

High material utilization

Cold forging is a method that involves little to no cutting. For example, when machining hex-head bolts or cylindrical head hexagonal screws from bars, the material utilization rate is only 25% to 35%, whereas with cold forging, the utilization rate can be as high as 85% to 95%.

High productivity

Compared to conventional machining, the forming efficiency of cold forged fasteners is dozens of times higher.

Good mechanical properties

Since the metal fibers in cold forged fasteners are not severed, their strength is much superior to that of machined ones.

Suitable for automated production

Cold forged fasteners are generally symmetrical parts, making them suitable for production with high-speed automatic cold forging machines, which is the main method for mass production.

In summary, cold forged fasteners have numerous advantages and are widely used in various fields. However, their manufacturing process also imposes high requirements on the die and materials. Therefore, when manufacturing cold forged fasteners, special attention needs to be paid to the selection and maintenance of the die, as well as the material handling processes.
