A BYD executive, He Zhiqi, shared information on his Weibo account regarding BYD's 9,000 ton die casting production line;
In the afternoon, I went to the factory to see the new car trial production and took the opportunity to visit our 9,000 ton large die casting production line.
The front and rear cabin floors were previously welded from 74 stamping parts to a single large die cast aluminum part, which greatly improved efficiency and reduced weight.
The equipment is domestically produced, and the molds are made by BYD.
From aluminum ingot to finished product, it is fully automated, which was unimaginable before.
I like the great progress of Made in China 👍
Previously, it was reported that BYD had invested in the construction of an "integrated body" die casting project, aka Gigacasting, for the future platform of its vehicles.
The initial investment consisted in 390.5 million Yuan ($54 million at the time) for the construction of a Gigacasting shop and the purchase of one 9,000 t die casting machine and its related supporting equipment.
Additional info revealed the plan is to adopt heat treatment free Al alloys and utilize both Front and Rear Underbody Gigacastings.
Later, general manager of the sales division of Denza (a BYD brand), reposted and shared optimism for the future of Gigacasting and die casting for body in white applications.
Large-scale die-casting is poised for significant growth in the automotive industry this year...
Using ultra-large die-casting machines, allows dozens or even hundreds of parts, previously requiring stamping and welding, to be die-cast in a single operation.
Applications are also expanding: from the current rear underbody, front engine compartment, and battery tray applications, they are gradually expanding to include mid-sections, seat frames, door frames, and even the integration of the entire vehicle body-in-white.
Integrated die-casting … can significantly improve efficiency, reduce costs, and enhance vehicle performance. As the technology matures and the industry continues to collaborate and innovate, it will expand even faster and encompass more diverse areas.
