The material of axle box is carbon steel and they are casted by arc furnace through Resin Sand Casting process. After casting, the railway axle box will be heat treated and then machined by CNC lathe. We have the capability of producing 10000 machined axle box in one month.
All of these axle box are tested strictly according to China standard, AAR standard, Russia standard or client`s requirements.
Sand Casting, also known as sand molded casting, is a metal casting process characterized by using sand as Sand casting, The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via a sand casting process.
Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, or carved directly into the sand.
