Tesla is set to redefine electric vehicle (EV) production with a pioneering approach that could cut its manufacturing costs in half. The innovations underpinning this potential breakthrough center around the “gigacasting” process, which Tesla used to mold parts of its Model Y, resulting in significant cost savings.
Tesla’s latest pursuit is to create almost the entire complex body of an electric vehicle in a single casting, rather than using approximately 400 separate components typical of conventional vehicles. This strategy, which is part of the “boxless” manufacturing plan shared by Elon Musk earlier this year, is expected to accelerate the production of more affordable electric vehicles while maintaining profitability.
One of Tesla’s most notable innovations is the use of 3D printing combined with industrial sandblasting to design and test large molds for mass production. This allows for cost-effective design adjustments, ensuring that the molds meet strict quality standards.
This method avoids the famous “gigacast dilemma”. Traditionally, manufacturing large structures from castings was cost prohibitive, with minor design alterations to metal molds costing up to $100,000. Tesla’s approach, which uses sand casting, dramatically reduces this cost to just 3% of what metal prototypes might entail. The flexibility offered by 3D printed sand molds also shortens the design validation process from a potential year to just two to three months.
One of the challenges Tesla faced was the behavior of aluminum alloys in different mold materials. But with specialized alloy formulations and post-production heat treatments, casting specialists were able to meet Tesla’s strict product quality criteria.
While the potential to revolutionize electric vehicle manufacturing is palpable, Tesla has some decisions to make, particularly regarding the type of gigapress to use. Regardless of the path chosen, Tesla’s ambitious enterprise is poised to shake up the auto industry, with implications that will be felt far and wide.
