The differences between forged and cast wheel hub processes are as follows:
- Manufacturing process:
- Forging: It is the process of applying pressure to a metal blank by forging machinery to make it undergo plastic deformation and thus obtain forgings with certain mechanical properties, shapes and sizes.
- Casting: It is the process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and finishing treatment, a casting with a predetermined shape, size and performance is obtained.
- Cost:
- Forging: The process is relatively complex and the manufacturing cost is high.
- Casting: The process is simple and the cost is relatively low.
- Weight:
- Forging: During the production process, through continuous stamping, the molecular structure is tight. Therefore, under the same size and strength, forged wheel hubs are lighter than cast wheel hubs.
- Casting: Since it is formed at one time, the molecular structure is relatively loose, so the weight is relatively heavy.
- Strength and toughness:
- Forging: After repeated forging, the bonding between metal molecules is closer, so the strength and toughness are better.
- Casting: The bonding between metal molecules is relatively loose, so the strength and toughness are relatively poor.
- Appearance:
- Forging: The surface is smooth and the metal texture is strong.
- Casting: The surface may have some defects such as pores and sand holes, and subsequent processing is required.
- Price:
- Forging: Due to the high manufacturing cost, the price is relatively expensive.
- Casting: Due to the low manufacturing cost, the price is relatively cheap.
In conclusion, forged and cast wheel hubs each have their own advantages and disadvantages. Consumers should make a comprehensive consideration based on their own needs and budgets when choosing.
