회사 프로필:
Baoding Longway company have excellent knowledge of metal forging, associated processes and assemblies. And long term focus on the production of large forging parts, production technologies include metal forging processing,heat treatment,mechanical processingetc. At present, it has formed a complete production process accessories chain.
제품 세부 정보:
Forged components are commonly found at points of shock and stress such as wheel spindles, kingpins, axle beams and shafts, torsion bars, ball studs, idler arms, pitman arms and steering arms. In forging, the metal is pounded and deformed, but the grain flow remains unbroken, allowing it to retain its strength.
Die forged hexagon head screw nuts applicaiton: mechanical and structural assembly, construction and in frastructure, automotive components, aerospace engineering, mining and excavation.
Heating: the steel is heated to a high temperature, making it malleable and ready for shaping.
Die forging:
- Initial shaping: the heated steel is placed between die molds and subjected to high pressure to form the rough shape of the hexagon head screw nut.
- Precision forging: further forging steps refine the shape and ensure precise dimensions and tolerances.
- Heat treatment: the forged parts undergo heat treatment processes such as quenching and tempering to enhance mechanical properties like hardness and strength.
Machining and finishing: Final machining processes ensure accurate threading and surface finish, and additional treatments (such as galvanizing or coating) may be applied for corrosion resistance.
