The cylindricity of the Connecting Rod s...
Forging is a processing method that uses forging machinery to exert pressure on metal blank to produce plastic deformation to obtain forgings with certain mechanical properties, certain shape and size. It is one of the two components of forging (forging and stamping). Forging can eliminate the defects such as as as cast porosity in the smelting process and optimize the microstructure. At the same ...
As a top leading steel forging company in China, we supply widely range of different steel forging parts in 40Cr, 42CrMo and C70S6 steel. Different forging methods have different processes, among which the process flow of hot die forging is the longest, and the general sequence is as follows: Blanking of forging blank; Heating of forging stock; Roll forging blank preparation; Die forging; Tri...
A forging part is an object in which the metal is pressed to shape the required shape or appropriate compressive force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates a refined particle structure and improves the physical properties of the metal. In the practical use of parts, a correct design can make the particle flow in th...
Forging production is one of the main processing methods to provide the blank of mechanical parts in the machinery manufacturing industry. Forging can not only obtain the shape of mechanical parts, but also improve the internal structure of metal and improve the mechanical and physical properties of metal. Generally, important mechanical parts with large stress and high requirements are mostly man...
Forging is widely used in automobile manufacturing. With the progress of science and technology and the continuous improvement of workpiece accuracy requirements, precision forging technology with the advantages of high efficiency, low cost, low energy consumption and high quality has been more and more widely used. According to the different deformation temperatures during metal plastic forming, ...
Defects caused by improper cooling after forging Cooling crack of forging parts: during the cooling process after forging, large thermal stress will be generated in the forging due to too fast cooling speed, or large structural stress may be caused by structural transformation. If these stresses exceed the strength limit of the forging, the forging will produce smooth and slender cooling cracks. N...
The reasons for insufficient hardness of forgings caused by improper post forging heat treatment process are: Quenching temperature is too low; Quenching heating time is too short; Tempering temperature is too high; Severe decarburization of forging surface caused by repeated heating; Unqualified chemical composition of steel, etc. Forging the reasons for the high hardness of forgings caused by im...
The defects generated during the cleaning of forging usually include the following: Excessive pickling will loosen the forged surface. This defect is mainly caused by the high depth of acid and the long residence time of the forging in the pickling tank, or by the unclean cleaning of the forging surface and the residual acid on the forging surface. Corrosion crack: if there is large residual stres...

Lubrication method and lubricant shall be selected before forging. Forging materials cover a wide r...
The recrystallization temperature of steel is about 460 ℃, but 800 ℃ is generally used as the dividing line, and hot forging is higher than 800 ℃; The temperature between 300 ℃ and 800 ℃ is called warm forging or semi hot forging. Forging can be divided into cold forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room tempera...
The main inspection methods of forgings IATF16949:2016 certified forging manufacturer The main inspection methods of forgings are as below: Chemical composition analysis Mechanical property test Low magnification test Metallographic high magnification inspection and NDT. Chemical composition analysis The general chemical composition analysis is mainly the content of carbon, manganese, silicon, sul...
Hot forging entails the heating of a workpiece to about 75% of its melting temperature. This allows for the flow stress and energy required to form the metal to lower, effectively increasing the rate of production (or strain rate). Hot forging aids in making the metal easier to shape as well as less likely to fracture. Steel, along with its alloys, are almost always hot forged for two main reasons...
Hot forging dies are mainly used to manufacture dies for pressure processing of workpieces under high temperature conditions, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. The commonly used hot work die materials are alloy die steels with medium and high carbon content and alloy elements such as chromium, tungsten, molybdenum and barium. Hot forging dies ...
