What are the manufacturing methods of wheel hubs and what are their differences?

[GabrielaLee]

Wheel hub manufacturing methods include forging and casting. The following are the specific differences between forged wheel hubs and cast wheel hubs: 1. In terms of wheel hub weight: Forged wheel hubs are made through high-strength forging, and under the same size and style, forged wheel hubs are lighter than cast wheel hubs. 2. In terms of style types: Forged wheel hubs, such as two-piece or three-piece designs, are usually assembled using rivets or welding (argon welding), and there is usually a noticeable color difference between the rim and the spokes; cast wheel hubs are formed in one piece with no color difference. 3. In terms of tapping sound: When a small metal rod is used to tap the wheel hub, forged wheel hubs produce a clear and pleasant echo, while cast wheel hubs produce a dull and low-pitched echo.
