Automobile forgings are a processing method that uses forging equipment to apply pressure to metal blanks to produce plastic deformation in the forging die cavity. They have certain shapes, sizes and mechanical properties.

The rapid development of automobiles has become the key to the separation of our forging industry from the casting and forging industry. The rapid development of the automobile industry has provided a broad space for the demand for forged products, and has also separated the forging industry from the casting and forging industry into one of the independent industries. According to data released by the China Forging Association, from the beginning of the new century to 2005, China's automobile production and sales increased from 2.34 million to 5.72 million. The statistics focus on total forging production, but do not break out forging production for cars separately. But in 2006, as automobile production and sales increased from 7.3 million to 18.26 million, the "Eleventh Five-Year Plan" was launched. "At the beginning of this year, the growth rate was as high as 76%. The Forging Association is increasingly aware of the driving effect of automobile growth on the forging market, and has begun to count and regularly publish the production and marketing levels of the entire industry. In 2006, the national automobile forging production and sales were 200 tons, which rose sharply to 480 tons in 2010, an increase of 140%, accounting for nearly 70% of die forgings, which shows the importance of automobiles to the forgings industry (see Table 3). In order to keep up with this change, during this period, first, Traditional forging companies have enhanced their capabilities through expansion, joint ventures, joint ventures, etc. Secondly, more and more new players have entered the forging field. To compete with these traditional forging companies, the number of important forging companies in China continues to increase, and important company personnel The total number has increased. Its growth has almost doubled, objectively expanding the overall scale of China's forging industry while continuously meeting market demand.

Automotive forgings can destroy the coarse dendrites and columnar grains in the cast metal, obtain equiaxed grains through recrystallization, and optimize the microstructure. At the same time, the mechanical properties of the forgings are generally better than similar materials. Maintain reasonable distribution of metal streamlines. Automobile forgings are basic safety components for the automobile manufacturing industry. Crankshaft, front axle, balance shaft, camshaft, half shaft, transverse shaft, connecting rod, gear, synchronizer ring, steering arm, steering knuckle, constant speed universal joint, rocker arm, fork and claw pole forgings are widely used in power, Ride and suspension components for commercial vehicles.
