TRAVAGLIATO, Italy, Feb 10 (Reuters) – By replacing all over 60 welded elements with a single module, gigantic aluminium die casting equipment produced by the likes of Tesla supplier IDRA Group are helping carmakers to simplify manufacturing and slice expenses by up to 40% in some spots.
Tesla (TSLA.O) has pioneered the use of massive casting equipment, also regarded as gigapresses, to make significant solitary parts of automobile underbodies, streamline output and lower the operate of even robots.
This has served it come to be the most financially rewarding battery electric car (BEV) maker.
Critics say the approach poses excellent and overall flexibility dangers, as a single flaw can compromise a total module, and make fixing far more challenging if anything goes mistaken.
But with the market having difficulties to maintain revenue margins amid surging uncooked supplies costs, carmakers which include Toyota (7203.T), Common Motors (GM.N), Hyundai (005380.KS), Volvo Cars and trucks and Chinese electrical car startup Nio (9866.HK) are turning to providers like IDRA for assist.

“The basic concept was to provide a technological innovation that could simplify the motor vehicle generation course of action,” IDRA general manager Riccardo Ferrario informed Reuters in an job interview at the company’s headquarters in Travagliato, northern Italy.
Battery packs now make up 25%-40% of the overall value of BEVs.
“You require to make the rest price a lot less,” Ferrario mentioned.
Automakers employing aluminium casting devices assert they can minimize investments needed to develop chassis – a vehicle’s 2nd most expensive element just after the engine – by 40%, and the average cost of their elements by 30%, Ferrario explained.
“It truly is a way to inevitably make BEVs anything for all pockets,” he reported.
IDRA, which was taken around by Chinese team LK Industries in 2008, has been acquiring gigapresses considering the fact that 2016. Opponents of IDRA and LK include things like Buhler Group in Europe, Ube Corp. (4208.T) and Shibaura Machine (6104.T) in Japan, as nicely as Yizumi (300415.SZ) and Haitian (1882.HK) in China.
Steel and plastic die casting has been largely utilised in production, but its application to massive aluminium underbodies in carmaking is comparatively new.
The international aluminium die casting current market was value nearly $73 billion previous year and is projected to best $126 billion by 2032, in accordance to an AlixPartners evaluation centered on Apollo Reports information.
Aluminium is prized for its mild body weight, and is also employed for other motor vehicle components like engines. The common material of the metallic in European made cars rose 20% to 179 kilograms in the 3 a long time to 2019, and is predicted to enhance to pretty much 200 kilograms by 2025, a analyze commissioned by foyer group European Aluminium reveals.
IDRA’s most recent and most important gigapress – the 9,000 – is the dimension of a tiny home and makes a clamping force of over 9,000 tons.
The business, which designed 100 million euros ($108 million) in revenues in 2021, does not disclose its buyers. But immediately after it posted a video of the initially Gigapress 9,000 ready for shipping and delivery, Tesla CEO Elon Musk explained it was for his company’s new cybertruck.
Tesla by now operates gigapresses in all its facilities, which include in Gruenheide, in close proximity to Berlin, exactly where it suggests it can churn out a Model Y in 10 hrs – about a few periods more rapidly than electrical autos designed by competition.
Ferrario stated IDRA had contracts with a few automakers and as several ‘Tier 1’ pieces makers. South Korea’s Hyundai Motor is amid them, sources familiar with the make a difference said.
Ralf Bechmann of manufacturing expert EFESO explained the gains of die casting would press it “to be applied to an rising variety of new versions of BEV automobiles, also by other manufacturers”.
Entrance and rear underbodies forged by gigapresses are now combined with battery packs to kind a 3-piece chassis for BEVs.
“I wager 80% of automakers will use gigapresses by 2035, at the very least for BEV automobiles based mostly on new platforms,” Ferrario claimed. “But the authentic question is: will we need to have even even bigger gigapresses?”
But not all automakers are convinced, and EFESO’s Bechmann cautioned that large module die casting demanded product style to be “super solid”.
“Correcting design flaws is much less complicated with a overall body designed up of a number of compact pieces instead than a solitary module,” he claimed.
Immediately after to begin with looking at die casting for its future Trinity design, Volkswagen (VOWG_p.DE) has backtracked, though BMW (BMWG.DE) has never expressed an fascination.
Ferrario claimed the vehicle market tended to be conservative and that no just one liked upending recognized procedures, but he turned down strategy that die casting posed a chance to careers at carmakers, noting human body-earning was already very automatic.
“The actual situation will be with corporations giving individuals little areas changed by our modules,” he explained.
