Tesla has combined a series of innovations to make a technological breakthrough that could transform the way it makes electric vehicles and help Elon Musk achieve his aim of halving production costs, five people familiar with the move said.
The company pioneered the use of huge presses with 6,000 to 9,000 tons of clamping pressure to mold the front and rear structures of its Model Y in a "gigacasting" process that slashed production costs and left rivals scrambling to catch up.
Terry Woychowski, president of U.S. engineering company Caresoft Global, said if Tesla managed to gigacast most of the underbody of an EV, it would further disrupt the way cars are designed and manufactured. In both cases the innovations, developed by design and casting specialists in Britain, Germany, Japan and the United States, involve 3D printing and industrial sand, the five people said. All spoke to Reuters on condition of anonymity because they are not authorized to speak to the media.
But Musk's vision from the start was to find a way to cast the underbody in one piece, despite the risks, the sources said. The design validation cycle using sand casting only takes to two to three months, two of the sources said, compared with anywhere from six months to a year for metal mold prototypes.The subframes in a car underbody are typically hollow to save weight and improve crashworthiness. At the moment, they are made by stamping and welding multiple parts together leaving a void in the middle.
The casting specialists overcame that by formulating special alloys, fine-tuning the molten alloy cooling process, and also coming up with an after-production heat treatment, three of the sources said. And once Tesla is happy with the prototype mold, it can then invest in a final metal one for mass production.
