World's first! The Bole 3000T semi-solid injection molding machine successfully manufactures 16kg+ grade 20-inch magnesium alloy wheels.

Lightweight manufacturing technology achieves a revolutionary leap.
Recently, there has been good news in China's high-end equipment manufacturing sector! Bole Intelligent Equipment Co., Ltd. has independently developed a 3000T ultra-large semi-solid injection molding machine, successfully completing the world's first single-piece weight of 16kg+ for a 20-inch integrated magnesium alloy wheel hub. This breakthrough not only refreshes the application record of semi-solid molding technology in the field of large-sized, lightweight automotive components but also sets a new benchmark for the global lightweight process of new energy vehicles.
01 Global Industrial Significance: Restructuring the Lightweight Competition Landscape
This success marks:
Cost revolution: Compared to traditional forging processes, production efficiency has increased by 5 times, and the cost per unit has been reduced by 50%, making magnesium alloy wheels commercially viable for mass production for the first time.
Technological autonomy: The Bole 3000T equipment has achieved 100% localization, breaking the technological monopoly of international giants such as Japan's Steel Works and Germany's Fuchs.
Zero-carbon manufacturing: the energy consumption of production is only 60% of that of low-pressure aluminum alloy casting, and the carbon reduction over the entire lifecycle exceeds 35%.
02 Future Outlook: The "Key Puzzle" of the Lightweight Revolution
Magnesium alloy wheels, as a core component of automotive lightweighting, not only fill the gap in global semi-solid forming technology for large-sized lightweight automotive parts but also signify that the industrial application of magnesium alloys has entered a new stage. Bole Intelligent Equipment will continue to optimize semi-solid injection molding technology to assist the global automotive industry in achieving more efficient energy-saving and emission reduction goals.
03 Conclusion
The successful launch of the world's first 16kg+20-inch magnesium alloy wheel rim not only demonstrates the technical strength of Bole Intelligent Equipment but also marks a milestone event in the global magnesium alloy wheel manufacturing field. As technology continues to mature and costs further decrease, magnesium alloy wheel rims are expected to become a "standard configuration" in the era of new energy vehicles, bringing a greener, more efficient, and safer future to the global automotive industry.
