The one-piece Wangqiao axle is made of steel tube special for trailer axle and formed by hot extrusion technology, which incorporates the advantage of hot spinning into our military technology. This kind of technology can ensure the metal deforms in the axle direction. After further quenching, tempering, and hardening, strength, rigidity and fatigue life of the axle beam can be greatly improved. Our technology greatly reduces the risk of axle fatigue fracture which can be caused by metal bending and deformation when spinning. Our product has exported to USA, Korea Republic, Malaysia, Philippines country as well as regions such as Middle East, Latin America and West Asia etc and received high praise at home and abroad.
