Shanxi Jianing Forging finishing gears, valve bodies, and automotive parts fine die forging live case study, intuitively presenting high-precision die forging processing and finished product dimensional accuracy, suitable for automotive, petrochemical, and hydraulic equipment support.
A hydraulic parts factory in Qingyuan, Guangdong, has long purchased die forgings for key components of hydraulic systems. The plant faced multiple practical challenges when searching for suppliers, including insufficient dimensional consistency of forgings, unstable internal tissue density, and excessive subsequent processing allowances leading to material waste and rising costs.
The main problems faced by this hydraulic parts factory in the original supply chain were: First, large fluctuations in forging shape tolerances, requiring frequent adjustments to subsequent machining parameters, which affected overall production line efficiency; 2. Fine looseness or segregation inside the product can cause some finished products to fail early under high-pressure conditions; 3. Low raw material utilization, increased scraps and processing waste, directly driving up the cost per piece.
To address these pain points, Jianing Forging has systematically optimized everything from mold design and forging processes to subsequent heat treatment processes. During the mold design phase, multiple rounds of simulation analysis optimize the parting surface and flash grooves, making the blank closer to the final product contour and reducing subsequent machining allowance. In the forging process, multi-directional die forging and relatively precise temperature control are used to distribute metal streamlines along the force direction, improving the density and mechanical uniformity of the forging. The heat treatment stage uses specialized quenching media and tempering curves to help hardness and toughness meet customer requirements. Subsequent batch verification by customers showed that the dimensional pass rate of forgings increased to over 98%, processing waste was reduced by about 15%, and the product's service life in hydraulic systems was extended, earning recognition from on-site technicians.
