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 ...
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 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...
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...
Since the establishment of the company, Yida has changed from an unknown small forging factory to a professional manufacturer of high-end automobile forging products. In the first half of 2022, under the influence of the epidemic, we went upstream and realized a 12% year-on-year increase in the main business income of forging products. 01 High Quality Forged Products As an important supplier ...
During the heat treatment of forgings, due to the large power of the heating electric furnace and the long holding time, the energy consumption in the whole process is huge. For a long time, how to save energy during the heat treatment of forgings has always been a problem. The so-called "zero heat preservation" quenching refers to the heat treatment process of quenching and cooling immediately wi...
Depending on the forming temperature steel forging can be divided into: Hot forging of steel Forging temperatures above the recrystallization temperature between 950–1250 °C Good formability Low forming forces Constant tensile strength of the workpieces Warm forging of steel Forging temperatures between 750–950 °C Less or no scaling at the workpiece surface Narrower tolerances achievable...
The inspection methods for forged parts include chemical composition analysis, mechanical property test, low magnification inspection, metallographic high magnification inspection and nondestructive testing. Chemical composition analysis The general chemical composition analysis mainly includes the content of carbon, manganese, silicon, sulfur and alloy elements. The forgings shall be sampled from...
