It is the metal component mounted on the axle at the center of the tire that supports it. It is also called the rim, steel rim, wheel, or tire rim. There are many different types of hubs, depending on their diameter, width, molding method, and material. The end cap is a rear cover installed behind the hub. Existing end caps are mostly manufactured by casting. The existing end cap production process mostly uses natural cooling to cool the cast end caps. This natural cooling process takes a long time, resulting in a long production cycle for end caps.
