Giga-Casting Accelerates for New Energy Vehicles

Automotive giga-casting (integrated die casting) is scaling up rapidly. The 2026 annual report on automotive integrated die-casting technology, released in February 2026, shows the process dramatically reduces the number of body parts, simplifies vehicle assembly, and improves supply-chain efficiency. In actual projects, large aluminum structural parts such as one-piece body castings and battery enclosure covers exceed 2.2 m² in projected area while achieving roughly 32% weight reduction versus conventional aluminum castings, making giga-casting a core path to vehicle lightweighting.

With continued growth in new energy vehicle production and sales, die-casting machine tonnages keep rising, and both capacity and process capability for aluminum precision castings are improving. Companies across the supply chain are expanding capacity, sustaining strong industry momentum.
