World's largest aluminum extrusion machine goes live in China with record-breaking specs
China's Taiyuan Heavy Machinery Group has officially delivered and commissioned the world's largest aluminum extrusion machine, now operating stably and receiving high praise from users.
The machine boasts an extrusion force of 235,000,000,000,000 newtons (235 trillion N), with a body measuring 57 meters (187 feet) long, 27 meters (89 feet) wide, and 18.7 meters (61 feet) tall-occupying nearly the area of two standard basketball courts. The extrusion cylinder has an inner diameter of 800 mm (31.5 inches), making it the most powerful aluminum extruder globally.
Annual production capacity reaches 20,000 tons of large-scale aluminum alloy profiles and 12,000 tons of finished products. It has already stably produced profiles up to 1.1 meters (43 inches) wide, reducing the need for welding and improving both manufacturing efficiency and product durability.
To ensure long-term reliability, the machine uses a stacked plate tension column design with multi-layer steel plates, replacing traditional solid columns. This innovation, combined with a fully pre-tensioned closed frame, improves pressure distribution, shortens manufacturing cycles, and enhances operational safety.
Precision control is another highlight. The intelligent system achieves temperature control accuracy of ±5°C (±9°F) and low-speed extrusion accuracy of ±0.02 mm/s, ensuring consistent product quality even under demanding conditions.
Taiyuan Heavy Machinery Group Co., Ltd. (TZ), founded in 1950 and headquartered in Shanxi Province, is one of China's largest manufacturers of heavy industrial equipment. The company specializes in machinery for mining, metallurgy, energy, and transportation, and has played a key role in developing high-end equipment for aerospace and rail transit. TZ is known for its engineering innovation and has contributed to numerous national infrastructure and industrial projects. Its aluminum extrusion technology supports China's growing demand for lightweight, high-strength materials in global competition.
