How powerful is the forged wheel rim that the players are pursuing?

Forging is a processing method that uses forging machinery to exert pressure on metal billets to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes, and is one of the two components of forging (forging and stamping). Forging can eliminate the metal in the smelting process of the as-cast loose and other defects, optimize the microstructure, and, because of the preservation of the complete metal flow line, the mechanical properties of the forgings are generally better than those of the same material.

The common process of forging wheel rims is mainly divided into milling, forging, and die forging.

The impact force or pressure is used to deform the metal between the upper and lower iron (anvil block) to obtain the required block blank, and the cake is formed by heat treatment and milling through the machining center. In simple terms, it is to forge a large cake of the Rim forging embryo, and then milling out the shape through CNC machining. Because the cake material is thick and the hardenability is poor in the heat treatment process, the material properties of the final product may not reach the better quality level of the forging process. Moreover, machining will destroy the forged crystal structure and affect the strength. Most of the domestic forging is done using this process.

Die forging is divided into open die forging and closed die forging. The metal blank is compressed and deformed in the forging die with a certain shape to obtain the forging, because the forging produced under this process belongs to the mold shape, the product wall thickness is uniform, and the performance after heat treatment is the best, so the quality of the wheel formed by die forging is the best and the weight is the lightest. Simply speaking, the aluminum material is processed directly through forging to produce a rough shape, and finally, it only needs to be milled off some raw edges. BBS, RAYS, and other big Japanese brands are using this process.

Compared with the casting wheel, the advantages of the forged wheel are high strength, higher safety, strong plasticity, light weight, good heat dissipation, and fuel saving. The disadvantage is that the price is slightly higher and the production cycle is longer.

If it is not under the track, the weight of the wheel on the vehicle is actually not so big, so the forged wheel is not so Good. According to their own needs and consumption level, choosing their own products is the best. Finally, no matter what the process, please choose the genuine rim; otherwise, the forging will become "broken".
