在最近的一次技术简报会上，丰田宣布了一系列新技术，以赶上其他汽车制造商的电动汽车扩张计划。其中之一是巨型铸造，其中选定的车身部件由两个或三个主要部件构成，简化了制造过程并降低了成本。

特斯拉是第一个广泛使用Giga Press超级压力机的公司，多家汽车制造商都试图效仿这种方法。吉利在 Zeekr 009 MPV 中使用了该技术，据报道通用汽车也将其用于其即将推出的旗舰电动汽车凯迪拉克 Celestiq。沃尔沃和现代也有类似的计划。

Giga Press超级压力机是一种高压压铸机。据信特斯拉首先在 Model Y 上使用了它，据报道仅用两到三个巨大铸件取代了由 70 个零件组成的组件。

这些房子大小的机器的夹紧力为 55,000 至 61,000 千牛顿（5,600 至 6,200 吨力），尽管它可能因配置和制造而异，因为特斯拉似乎正在使其 giga 压力机供应商多样化，而不是仅仅依赖意大利的伊德拉。瑞士布勒和中国力劲集团是该领域的其他重要参与者。

Giga Press铸造的好处是多方面的。据一些专家称，该技术使特斯拉能够将 Model Y 的后车身底部制造成本降低 40%。据Autoblog报道，对于 Model 3，特斯拉从装配中移除了 600 个机器人，因为Giga Press压力机简化了生产。与此同时，丰田表示，该技术将使流程和工厂投资减少一半。

广泛采用技术的另一个原因是可能减轻重量。EV 电池很重，制造商希望在其他地方补偿额外的重量。Giga press 可能还通过消除数十个单独的零件来减少碳排放。

尽管该技术存在一些缺陷。万一发生事故，更换大型部件可能比更换较小的部件花费更多。据《欧洲汽车新闻》报道，尽管如今车身制造高度自动化，但这种做法也会影响供应较小部件的企业。

The Giga Press: Tesla’s Game-Changing Manufacturing Process Goes Mainstream

Half a dozen carmakers are adopting giga casting after Tesla to reduce costs and simplify manufacturing.

In a recent technical briefing session, Toyota announced a raft of new technologies as it catches up to other carmakers in electric vehicle expansion plans. One of them is giga casting, wherein select car body parts are constructed from two or three main components, simplifying the manufacturing process and reducing costs.

Tesla was the first to widely use the giga press, and multiple carmakers have attempted to emulate the approach. Geely uses the technique for the Zeekr 009 MPV and General Motors is reportedly using it for its upcoming flagship EV, the Cadillac Celestiq. Volvo and Hyundai have similar plans as well.

The giga press is a high-pressure die-casting machine. Tesla is believed to have first used it on the Model Y, reportedly replacing assemblies consisting of 70 parts, with just two to three huge castings.

The house-sized machines have a clamping force of 55,000 to 61,000 kilonewtons (5,600 to 6,200 tons of force), although it may vary depending on configuration and make, as Tesla appears to be diversifying its giga press suppliers, and not rely solely on Italy’s IDRA. Switzerland’s Bühler and China’s LK Group are other big players in the space.

Giga casting benefits are multifold. The technology allowed Tesla to reduce the Model Y's rear underbody manufacturing costs by 40 percent, as per some experts. For the Model 3, Tesla removed 600 robots from the assembly, as the giga press simplified production, reported Autoblog. Meanwhile, Toyota has said the technology will reduce processes and plant investment by half.

Another reason for the wider adoption of technology is the potential weight savings. EV batteries are heavy, and manufacturers look to compensate for the additional weight elsewhere. Giga press presumably reduces carbon emissions as well by eliminating dozens of individual parts.

Although there are a few pitfalls to the technology. In case of accidents, replacing huge parts could cost a lot more than replacing smaller components. Even though body manufacturing is highly automated nowadays, the practice can also impact businesses supplying smaller components, according to Automotive News Europe.
