Except for internal control of our factories, DK metals is also involved in QC process of products that we developed. This has ensured our products to earn great reputation from our customers.

 

Forging is a workpiece or blank obtained by forging and deforming metal billets. The mechanical properties of the metal billet can be changed by applying pressure to the metal billet. According to the temperature of the billet during processing, the forging can be divided into cold forging warm forging and hot forging. Cold forging is usually done at room temperature, and hot forging is done at a recrystallization temperature higher than that of a metal blank.

The loose of metal can be eliminated by forging. Holes are made to improve the mechanical properties of the forgings.

Usage:

1, general industrial forgings refer to the civil industry, such as machine tool manufacturing, agricultural machinery, farm implements manufacturing and bearing industry.
2, forgings for hydrogenerators, such as main shaft and intermediate shaft.
3, forgings for thermal power stations, such as rotors, impellers, retaining rings, etc.
4, metallurgical machinery, such as cold roll, hot roll and herringbone gear shaft.
5, forgings for pressure vessels, such as cylinders, ring flanges and heads.
6, marine forgings, such as crankshaft, tail shaft, rudder rod, thrust shaft and intermediate shaft.
7, forging and pressing machinery and equipment, such as hammer head, hammer bar, hydraulic press column, cylinder body, wheel shaft press mounting machine's prop and cylinder body, etc.
8, modular forging is mainly used for forging dies for hot forging hammer.
9, automotive industry forgings, such as left, right steering knuckle, front beam, coupler, etc., according to statistics, in automobile, forging parts account for 80% of its quality.
10, forgings for locomotives, such as axles, wheels, leaf springs, crankshafts of locomotives, etc., according to statistics, the forging parts in locomotives account for 60% of their quality.
11, forgings for military industry, such as gun barrel, door body, breech bracket and traction ring, etc., according to statistics, forging parts account for 65% of the quality of tanks.
Characteristic:

1, the weight range is large. The forgings are small to several grams to hundreds of tons.
2, the quality of the casting is higher than that of the casting. The mechanical properties of the forgings are better than those of the castings, which can bear large impact forces and other heavy loads. Therefore, any important and large force parts are used forgings. For high carbides steel, forging is better than rolled steel. For example, high speed steel rolling material (or forging material) can be used only after forging. In particular, the high speed steel milling cutter must be changed.
3, the weight is the lightest. Under the premise of ensuring the strength of the design, the weight of the forgings is lighter than the weight of the castings. This reduces the weight of the machine itself. It is of great significance for the vehicles, aircraft, vehicles and characters.
4, save the raw materials. For example, the crankshaft of the static heavy 17kg used in the car is 189% of the weight of the crankshaft when the rolling material is forged. While the die forging is used, the chip is only 30%, and the machining time is also shortened by 1/6.
Precision forging can not only save more raw materials, but also save more machining hours.
5, high productivity. For example, the use of two hot die forging press forging radial thrust bearings, can replace 30 automatic cutting machine tools. When the M24 nut is produced by the top forging automaton, the productivity of the six axis automatic lathe is 17.5 times.
6, free forging is very flexible. Therefore, forging technology is widely used in some factories to produce various accessories.
