Introduction: Decoding the Advancements in “Tesla Giga casting”

Tesla, the pioneering electric car manufacturer, is on the verge of a revolutionary transformation in its production techniques. Their “giga casting” technology, which has already made significant inroads in production cost efficiency, is poised for a groundbreaking upgrade. This shift is expected to redefine the way the underbody of electric vehicles is constructed, highlighting Tesla’s commitment to innovation and cost-effectiveness.

Based on recent insights from a visit to Tesla’s expansive Shanghai factory, the Shanghai Securities News divulged that the company is focusing on a critical enhancement of its “giga casting” technology. This upgrade aims to die-cast almost the entirety of an electric vehicle’s underbody in one seamless piece. Though the specifics concerning the timeline and place of this upgrade remain secret, it’s evident that Tesla’s promise to refine its production courses remains firm.

Since its start, Tesla has been at the vanguard of trade inventions. They have adeptly employed massive presses, exerting a staggering 6,000 to 9,000 tons of clamping pressure, to shape the structural elements of their Model Y. This Tesla Giga casting approach has drastically reduced production expenses. Interestingly, at their Shanghai facility, which stands as Tesla’s largest global manufacturing unit, the company has adeptly employed this method. Since 2020, they have been die-casting the rear of the Model Y, a move that has translated into a commendable 40% reduction in associated production costs.

The Global Ripple Effect

Tesla’s pioneering efforts in the realm of gigacasting have not gone unnoticed. Several electric vehicle (EV) manufacturers in China, including prominent names like Xpeng and Geely’s Zeekr, have taken a leaf out of Tesla’s book. Drawing inspiration from the production cost efficiency of the electric vehicle underbody casting approach, these manufacturers are now integrating “giga pressing” into their production lines. This widespread adoption emphasizes the technology’s potential for enhancing vehicle light weighting and significantly slashing manufacturing costs.

Potential Impacts and the Way Forward

The innovation around the giga casting technology underscores Tesla’s unwavering commitment to enhancing the efficiency and affordability of electric vehicle production. By focusing on consolidating the production of the Electric Vehicle Underbody into a singular cast, Tesla is not just advancing its manufacturing processes but also setting a benchmark for the global EV industry. 

This endeavor is in line with Tesla’s broader vision of hastening the world’s transition to sustainable energy. By driving down manufacturing costs, Tesla can potentially lessen the overall price point of their automobiles, making electric vehicles more accessible to a broader consumer base. This stage, in turn, could expedite the world-wide shift from traditional fossil fuel-reliant vehicles to cleaner, more maintainable electric replacements.


As Tesla continues its quest for innovation and production efficiency, the advancements in giga casting represent a pivotal moment in electric vehicle manufacturing. While the precise details of this upgrade are eagerly awaited, the potential implications for the EV industry are profound. With Tesla leading the charge, the future of electric vehicle production promises greater efficiency, affordability, and sustainability.


Tesla is set to enhance its giga casting technology to die-cast nearly the entire underbody of electric vehicles in one piece, as revealed by the Shanghai Securities News. This innovative approach, already implemented in their Shanghai factory, has reduced production costs significantly, with the Model Y’s rear casting alone resulting in a 40% cost cut since 2020. The company’s pioneering giga casting method, which utilizes massive presses for die-casting, has inspired other electric vehicle manufacturers like Xpeng and Geely’s Zeekr to adopt similar techniques. This evolution underscores Tesla’s commitment to refining electric vehicle production efficiency and sets a global benchmark for sustainable vehicle manufacturing.
