# 16,000-Ton Gigacasting Machine

Dongfeng's 16,000-ton die casting machine — the world's largest — casts integrated EV chassis and battery trays in a single shot, nearly doubling Tesla's capability
- Technology Readiness Level: 8/9
- Impact: 3/5
- Investment: 4/5
Before 2018, a 'large' die casting machine was 4,000 tons. Tesla raised the bar to 6,000 tons for the Model Y (2020) and 9,000 tons for the Cybertruck (2023). Dongfeng entered production at 16,000 tons in 2026 — four times the pre-gigacasting industry standard.

At this tonnage, Dongfeng casts integrated chassis and battery tray structures in a single shot — components that require multiple machines and dozens of assembly steps at any other automaker. The single-piece casting eliminates hundreds of welds, reducing weight, improving structural rigidity, and cutting production time.

No Western machine is operating above 9,000 tons today. China took Tesla's own manufacturing innovation and nearly doubled it. The pattern is consistent: identify a manufacturing bottleneck, set a target at 2x the incumbent, then invest until it's achieved.
