In a current technical briefing session, Toyota introduced a raft of latest applied sciences because it catches as much as different carmakers in electrical automobile enlargement plans. Certainly one of them is giga casting, whereby a automotive physique is constructed from two or three primary parts, simplifying the manufacturing course of and lowering prices.
Tesla was the primary to extensively use the giga press, and a number of carmakers have tried to emulate the method. Geely makes use of the megacasting approach for the Zeekr 009 MPV and Common Motors is reportedly utilizing it for its upcoming flagship EV, the Cadillac Celestiq. Volvo and Hyundai have related plans as effectively.
The giga press is a die-casting machine used to stamp aluminum sheets into giant components of a automotive’s physique. Tesla is believed to have first used it on the Mannequin Y, reportedly changing assemblies consisting of 70 components, with simply two to a few large castings.
The home-sized machines have a clamping drive of 55,000 to 61,000 kilonewtons (5,600 to six,200 tons of drive), though it might range relying on configuration and make, as Tesla seems to be diversifying its giga press suppliers, and never rely solely on Italy’s IDRA. Switzerland’s Bühler and China’s LK Group are different huge gamers within the house.

Giga casting advantages are multifold. The expertise allowed Tesla to scale back Mannequin Y manufacturing prices by 40 %, as per Autoblog. For the Mannequin 3, Tesla eliminated 600 robots from the meeting, because the giga press simplified manufacturing considerably. In the meantime, Toyota has mentioned the expertise will cut back processes and plant funding by half.
Another excuse for the broader adoption of expertise is the potential weight financial savings. EV batteries are heavy, and producers look to compensate for the extra weight elsewhere. Giga press presumably reduces carbon emissions as effectively by eliminating dozens of particular person components.
Though there are just a few pitfalls to the expertise. In case of accidents, changing large components might value much more than changing smaller parts. Furthermore, it could possibly be a painstaking job for legacy automakers with established manufacturing processes to include giga casting.
Despite the fact that physique manufacturing is extremely automated these days, the follow may impression companies supplying smaller parts, in accordance with Automotive Information Europe.
