Ford has now cast more than 5,000 giant aluminum structures for the Fathom, the midsize electric pickup it plans to launch in 2027 for under $30,000. Each truck is designed around two of them, one for the front and one for the rear, and the pair replaces 146 separate structural parts. The castings are real hardware already moving through a Kentucky assembly plant, which is a step past a concept render.

The company counts 5,000 as a milestone for prototype and process testing, not as a production run, and the truck has no on-sale date beyond 2027.
Two castings instead of 146 parts
The update came from Vladimir Bogachuk, Ford’s chief engineer for advanced vehicle structure architecture, in a post on Ford’s From the Road site. Bogachuk described the unicastings as the front and rear structures of the Fathom, cast at Ford’s Shelbyville Technical Center and shipped to the Louisville Assembly Plant, where they support process testing and prototype builds. Ford says the design goal is lower mass and better energy efficiency, which matters for an electric truck priced to compete on cost.
Electrek, which broke down the post in its report on the 5,000 unicastings, framed the move as Ford adopting the approach Tesla popularized with its Giga Press. Tesla’s first press, with roughly 6,000 tons of clamping force, began running at Fremont in 2020 and cast the Model Y’s rear underbody as a single piece in place of 70 parts. Ford’s two-casting layout swaps out more than twice as many parts, though Tesla’s casting was a single section of the floor and Ford’s covers both ends of the truck.
How a casting gets from furnace to Louisville
Ford melts aluminum ingots at about 1,300 degrees Fahrenheit, or 700 degrees Celsius, moves the metal to a holding furnace, and injects it into a mold on a casting machine. A robot lifts the finished part out and drops it into a quench tank to cool. From there an operator checks it by eye in a fixture, and parts from each batch go through machining and further checks.
The inspection list is long. A coordinate measuring machine in a climate-controlled room verifies dimensions, hole positions and alignment. An industrial X-ray system hunts for pores and voids inside the metal, an optical scanner maps the surface, and the materials lab runs tensile tests for strength and chemical tests on alloy samples. Ford holds each batch until every test passes, and only then approves shipment to Louisville. Large castings live or die on that gate, since a hidden void in a structural part is the kind of flaw that cannot be fixed on the assembly line.
The repair question that makes rivals hesitate
Cost of repair is the main reason many automakers have stayed away from large castings. Electrek reports that a single damaged structure can turn a moderate crash into a total loss, because a casting cannot be straightened or patched the way a welded assembly of many stamped parts can. Cory Steuben, a Lucid executive, told the outlet that insurance concerns led Lucid to skip gigacasting entirely.
Ford’s answer, per its own post, is to engineer the unicastings for what it calls modular repairability, and to keep working on shorter cycle times at the casting machine. The post does not say how a damaged section would be cut out or replaced, or whether insurers have signed off, so the repair argument is still a promise rather than a documented process.
The industry is split. Electrek lists Volvo, Xiaomi, Xpeng and Honda among the companies committing to large presses, and Stellantis among those that have said they will not invest, with Hyundai pushing its own casting plan back two years. Ford sits with the adopters, at a price point where every dollar of assembly cost shows up on the sticker.
Why the casting is tied to a sub-$30K price
The castings change how the truck is assembled, not only what it is made of. Ford’s post says they enable a new assembly method on its Universal Production System, in which the line splits into three main branches so sections of the vehicle are built in parallel and joined at the end. Electrek identifies the branches as front, rear, and a battery pack with interior floor, and reports Ford’s claim that the method could be up to 40 percent faster than its current assembly, or about 15 percent faster net after savings are reinvested in automation and insourcing.
Those numbers come from Ford and are projections for a line that is still being retooled, so they are a target rather than a result. The price target is firmer in Ford’s messaging: Electrek’s coverage of the truck’s home-power features reports the Fathom arriving in 2027 for less than $30,000 on the same Universal EV Platform that Electrek first covered in February. Ford’s post on the Fathom’s bidirectional power gives a starting price of $28,350 for the vehicle itself, and the home-power hardware is priced separately, with no installed cost published yet.
The open question is whether 146 fewer parts translates into a cheaper, durable truck once insurers and body shops weigh in. Ford has the first 5,000 castings to show for it, and the Louisville retooling and 2027 launch will test whether the savings Bogachuk’s team is chasing survive contact with real crash repairs.
