Introduction – What is cold forging?

Cold forging / cold heading is a manufacturing process used to shape metal products without the application of heat. It is typically used to form parts with increased strength or to reduce the overall weight of components. The process is also used to manufacture parts with complex shapes or parts with intricate geometries.

Benefits of Cold Forged Parts:

• Excellent dimensional accuracy and repeatability
• Increased strength due to grain flow lines in the metal
• Lower cost compared to CNC machining from bar stock
• Faster production rates than machining
• Wide range of shapes and geometries possible

Advantages

The main advantages of cold forging are:

1.Strength

Cold forging makes it possible to craft parts with very high strength, since the absence of heat reduces the risk of introducing weaknesses such as porosity to the part.

2.Weight Reduction

Since there is no heat involved, the process makes it possible to reduce the overall weight of the parts being manufactured.

3.Time

The process of cold forging is much faster than other manufacturing processes like machining. This makes it an attractive option when it comes to mass production of parts.

Disadvantages

The main disadvantages of cold forging are:

1.Cost

The tooling and associated setup costs for cold forging are typically higher than other manufacturing processes.

2.Material Limitations

Cold forging is typically limited to materials with low melting points. This limits the material choice when it comes to producing parts.

3.Choice of Design

The design of the part has to be well thought out for cold forging to be successful. Parts with complex shapes are typically not suitable for cold forging.

Cold Forged Blanks for CNC Machining

Cold forging is often used to produce the pre-machined blanks that are used for machining parts. This can help to improve the machining efficiency of the part and reduce the overall costs of the machining process.

The use of pre-machined blanks also ensures that the parts are being made with consistent quality, as the process eliminates inconsistencies that could be caused by variations in the machining process.

The near net shape blanks provide maximum machining efficiency while maintaining extremely tight tolerances. Typical applications include automotive, aerospace, medical, and industrial components.

Customized Square Nuts By Cold Forging Service

Ming Xiao Metal Parts Manufacturing custom produce cold  forging parts(such as bolt,nuts,screw,metal pin,metal stud) according to customer’s drawing or sample, we made nonstandard fasteners by cold heading / cold forging or lathing – handle pins, Dowel Pins, nonstandard hex head bolts,squre head bolt,philips head screws,pan head screws,nonstandard screws, nonstandard pins, nonstandard nuts of square nuts,self lock nut,all kinds of metal studs,etc.

As the cold heading technology has high productivity, good product quality, and I greatly reduces material consumption, reduces production cost and improves labor conditions, it is widely used in the production of mechanical manufacturing, especially standard fasteners, in which the most representative products produced by multi position cold heading machines are bolts，screws and nuts.

Generally we use cold forging process to produce rough parts, then machining it again by turning,milling and other machining processes to make the parts with good surface and dimensions.This way can make the production cost reduced and the producing processes more less.it’s a more competitive way to produce high quantity parts.

Custom Quality Cold Forging Parts From China

Ming Xiao Metal Parts Manufacturing custom produce cold forging parts(such as bolt,nuts,screw,metal pin,metal stud) according to customer’s drawing or sample, we made nonstandard fasteners by cold heading / cold forging or lathing – handle pins, Dowel Pins, nonstandard hex head bolts,squre head bolt,philips head screws,pan head screws,nonstandard screws, nonstandard pins, nonstandard nuts of square nuts,self lock nut,all kinds of metal studs,etc.

Cold forging also named cold heading process is one of the new processes for machining less and less cutting metal pressure. It is a kind of molding deformation produced by metal under external force, and the metal volume is redistributed and transferred by means of mould, so as to form the required parts or blank processing method. The cold heading process is most suitable for producing standard fasteners such as bolts, screws, nuts, rivets and pins.

The cold heading is carried out under the condition of normal temperature. The mechanical properties of metal parts can be improved by cold heading. The following table is a comparison of mechanical strength between cold heading bolts and cutting bolts.

It can be seen from the table that, no matter what type of bolt, the tensile strength of the cold heading is about 10% higher than that of the cutting process, and some can even increase by 20%. This is because the metal fibers of the cold heading product will not be cut off, the internal structure of the metal is compacted, and the working hardening is accompanied by the existence of the working hardening phenomenon, so the mechanical properties of the metal are improved.

2. cold heading technology can improve the utilization of material. Taking the cold heading bolt as an example, the material utilization rate of the new process “concave hole” six angle bolts can reach more than 99%. In addition to the loss of material head and tail, no cutting process was achieved. For cutting, the material utilization rate is only 40%. The material utilization rate of the cold heading nut can also reach about 80%, and the material utilization rate of the cutting nut is only 54%.

3. cold heading technology can greatly improve the productivity. If the cold heading nut is compared with the original cutting process, the productivity will be increased by 25~30 times.

4. cold heading process can improve the surface finish and ensure product accuracy. The general smoothness is up to V5, and the special requirement is V6. For large quantities of bolts, nuts and so on, it can completely guarantee its accuracy.

As the cold heading technology has high productivity, good product quality, and I greatly reduces material consumption, reduces production cost and improves labor conditions, it is widely used in the production of mechanical manufacturing, especially standard fasteners, in which the most representative products produced by multi position cold heading machines are bolts，screws and nuts.

Generally we use cold forging service to produce forged rough parts, then machining it again by turning,milling and other machining processes to make the parts with good surface and dimensions.This way can make the production cost reduced and the producing processes more less.it’s a more competitive way to produce high quantity parts.
