Shanxi Jianing Forging adopts mature precision die forging processes, capable of producing gears, valve bodies, automotive swing arms, piston rods, and impeller die forgings. It offers high dimensional accuracy, and can be processed from carbon steel, stainless steel, and alloy steel, meeting the needs of multiple industries.
As a key load-bearing component of automotive suspension, the swing arm endures long-term impact and alternating loads. Ordinary cast or welded parts are prone to fatigue fracture, large dimensional deviations, and short service life. The swing arm manufactured using fine die forging processes increases material density and streamlined distribution from the source, enhancing fatigue resistance and facilitating continuous operation.

Ordinary cast or welded parts are prone to fatigue fracture, large dimensional deviations, and short service life. The swing arm manufactured using fine die forging processes increases material density and streamlined distribution from the source, enhancing fatigue resistance and facilitating continuous operation.
Automotive swing arm die forgings are formed from high-quality alloy steel through a fine forging process in one step, then undergo heat treatment and fine machining, achieving relatively high strength, high toughness, and excellent dimensional consistency. The products are widely used in passenger car and commercial vehicle chassis systems, effectively optimizing traditional casting or stamping-welded structures to meet the dual requirements of lightweight and reliability.
Selecting high-quality alloy steels (such as 40Cr, 42CrMo), strictly controlling chemical composition and post-forging quenching and tempering helps stabilize material properties.
Uses fine die forging technology for near-net forming, reducing subsequent processing allowance and improving material utilization.
Metal streamlines are continuously distributed along the part contour, and fatigue strength is superior to castings of the same specification.
Molds and processes achieve dimensional consistency in mass production, with individual tolerances controlled within ±0.2mm.
The surface has a high finish, and rust prevention treatments such as sandblasting, electrophoresis, or Dacro can be selected according to customer requirements.
This product is customized according to drawings; actual prices should be comprehensively evaluated based on specific models, material grades, annual demand, and surface treatment requirements.
