Competitive Advantage:

Cold forging is a manufacturing process involving the shaping of metal using localized compressive force with no or less cutting. It’s a kind of process wherein the cold metal flows plastically by volume re-distributing or transferring under compressive forces into a variety shapes within the dies to obtain desired parts or blanks. It relies on the die to control the metal flow and forms parts by metal massive volume transferring. The frequently-used extrusion methods are: forward extrusion, backward extrusion, combined extrusion and ironing process. It is a kind of advanced production technology of high-precision, high efficiency, environmentally friendly and low power consumption, often used for large-scale production of small and medium-sized forgings.

Advantage of Cold Forging.

Cold forging process has the following advantages relative to the die-casting and traditional craft:

1)Conservation of raw materials. Cold extrusion is the process to make desired shaped metal parts by using the deformation of metal, can be a significant reduction in machining and increase material utilization. The material utilization can reach to 80% or more.

2)Improve labor productivity. Instead of cutting process, cold extrusion process can make productivity improvements in fabricating parts.

3)The work pieces can be obtained the desired surface roughness and dimensional accuracy. The accuracy of parts can reach to level IT7 ~ IT8. The surface roughness can reach to Ra0.2um ~ Ra0.8um, sufficient to meet Ra3.2um of the part. Parts of higher surface quality requirements can be simply obtained by finishing machining.

4)Improve the mechanical properties of the parts. Metal flow makes the interior of the part to form a reasonable distribution fiber flow lines, the strength of the parts is much higher than the performance of the raw materials, such as the mechanical properties of strength, toughness, hardness, fatigue resistance, tightness, and surface treatment incompatibilities.

5)Reduce the cost of parts. The cost of parts can be greatly reduced because of the advantage of cold extrusion process in raw material conservation, productivity improvements, machining reduction and possibility of replacing higher grade material to lower grade one.

It can be got from the above characteristics, cold extrusion technology has outstanding superiority compared with other current processing methods. This has opened up a broad road for cold extrusion to replace cutting, forging, casting and tension processes in machinery parts fabrication industry.
