The difference and comparison between forged wheels and cast wheels

1. From the aspect of object form transformation:

Casting wheels refers to liquefying solid metal, and then putting the shapeless molten metal into the mold to obtain different shapes (solid-liquid-solid).

Forged wheels are the transformation of a solid of one shape into a solid of another shape. That is, the solid changes from one shape to another (solid-solid) at high temperature.

2. In terms of focus:

Casting a wheel is a process of casting molten metal into a model to obtain a casting. The foundry profession focuses on the metal smelting process and the control of the process in the casting process

Forged wheels are plastic forming in a solid state, which can be divided into hot working and cold working. Such as extrusion, drawing, pier roughing, punching, etc. all belong to forging.

3. In terms of molding speed:

Casting wheels are formed at one time. The molten liquid metal fills the cavity and cools down. Pores are likely to occur in the middle of the part.

Forged wheels are formed slowly, mainly by extrusion at high temperature. Can refine the crystal grains in the part.

4. From the difference in performance:

Cast steel is brittle in performance and cannot be heat treated.

Forged steel has a finer structure, good toughness and strength, and can be subjected to various heat treatments.

Casting wheels advantages: low price, short production cycle; disadvantages: low strength, will be easily crushed after severe impact; it is also sufficient for family car owners who do not have too many requirements for handling and are pursuing economical benefits.

Forged wheels advantages: light weight, good heat dissipation, high strength, not easy to crush after impact, higher safety, strong plasticity, and can be customized at will; disadvantages: slightly higher price, long production cycle; forged wheels are suitable for the pursuit of performance, control and personality.
