On January 20, 2026, Duoli Technology held the commissioning ceremony for its 9,200 ton ultra large die casting island in Jinhua, marking the official production launch of the rear Gigacasting component co developed with Leapmotor.
The project spans a total construction area of 5.4 hectares and follows a phased approach, ultimately encompassing a complete production ecosystem, including die casting, stamping, hot forming, and welding, to deliver end-to-end manufacturing capabilities for large scale structural parts.
At the heart of the project is the 9,200 ton (Carat 920) die casting island supplied by Swiss manufacturer Bühler. The equipment is dedicated to producing structural components for new energy vehicle (NEV) makers, with Leapmotor serving as the inaugural customer.
Duoli Technology has rapidly expanded its footprint in ultra large die casting, establishing advanced gigacasting islands and integrated production lines across multiple cities and provinces in China. Full list available on The Gigacasting Database.
Another facility is prepearing Gigacasting components for Leapmotor’s future vehicles, including the upcoming D19 flagship SUV
CITIC Dicastal's Gigacasting facility in Jinhua, China, has reached a pivotal stage, with final construction of the factory building underway and initial equipment trials in progress. The project team is fully committed to achieving mass production as soon as possible.
The first phase, currently in commissioning, features a fully automated die-casting production line centered on Yizumi's 10,000 ton die casting machine.
Equipped with a two-cavity mold, this line is designed to produce 300,000 front underbody (FUB) longitudinal beam sections annually. Each machined FUB casting weighs 34.3 kg.
Following the completion of Phase 1, Phase 2 will introduce a 7,500-ton die-casting line capable of manufacturing 120,000 rear underbody gigacastings per year at full capacity, with each machined part weighing 50 kg.
Leapmotor’s casting does not integrate the shock towers, crash cans, or large wheel arches. Instead, it adopts a simpler, more streamlined solution that is easier to integrate in the body design.
Although this solution may be lighter and twice as many parts can be made with one machine, it offers fewer part reductions and lower cost savings compared to a fully integrated front underbody casting.
Below are examples of similar designs, including Wencan’s solution for AITO and Changan’s for its Nevo brand.
