What are the manufacturing processes for wheel hubs?

The key to melting equipment lies in the control of furnace temperature; the refining methods for aluminum liquid include the gas method and the flux method. Low-pressure casting machines are mainly of the holding furnace molten pool type. The X-ray tubes used are imported 160KVA metal tubes, capable of penetrating aluminum alloy with a thickness of over 50mm. Heat treatment; mechanical processing. Dynamic balance testing; airtightness testing; painting.
I've been working in automotive repair and I'm very familiar with wheel manufacturing. First, aluminum alloy or steel is melted into liquid metal, then poured into molds for low-pressure casting or gravity casting, which ensures fast forming and low cost. Next, heat treatment is applied to eliminate stress and enhance strength; mechanical processing is used to turn the wheel spokes and center hole; finally, surface treatments like painting or electroplating are applied for rust prevention and shine. The entire process requires strict quality control, such as non-destructive testing for cracks, to ensure safety and durability. From an environmental perspective, waste recycling is also crucial to prevent pollution. I've seen automated production lines in factories that can produce hundreds of wheels a day—high efficiency, but worker safety measures must never be overlooked.
