With the high speed development of auto industry,China’s automobile steering knuckle is gradually towards specialized,advanced. In 2007,China’s weapon equipment group company self-developed aluminum alloy steering knuckle smooth through the national nonferrous metal and electronic material analysis and test ce nter ofthe test, can meet the international similar product standard, become our country the first success fully developed the aluminum allo y of steering joint enterprise, fill the product of domestic blank. In 2008,China successfully built a has the Chinese the most ad vanced technology,minimum investment scale, the lowest manufacturing costs and highest input-output ratio the shortest investment return cyc le o fproduction capacity of180000 pieces of heavy trucks to section o f the auto matic production line, the production out external shape in good condition, internal quality, the products consistency of strong, organization performance standards steering knuckle products.

Auto steering knuckle processing is divided into blank manufacturing and finished product machine to add. At present, the blank mainly forging is given priority to, also have made by casting the blank, but is less.
