With its reliable security and better quality, our forged wheels can be customized to meet your individual needs in size and design and thus present a combination of beauty and practicality.

Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Through forging, it can eliminate the defects such as loose as-cast produced in the metal smelting process and optimize the microstructure.

At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of related machinery with high load and severe working conditions, forgings are mostly used in addition to simpler shapes that can be rolled, profiles or welded parts.

The temperature of the rough embryo formed by high temperature and high pressure is very high, and the surface is covered with black carbides, which must be handled by a fork motive. The rough embryo after pickling surface treatment already has the embryonic shape of a wheel hub;

After long-term reprocessing and heat treatment of the T4 and T6 heat treatment machines, the grains of the rough embryo will be firmer and the toughness of the product will also be improved;

Forged aluminum ring must rely on mechanical processing to process the rough embryo to the rim forming, so the work content includes bead forming, screw hole drilling, disk turning, detail processing and other steps;

Before painting, you must check the rim surface for flaws.
