GM snatches key Tesla gigacasting supplier TEI
For years, a little-known company called Tooling & Equipment International (TEI) has helped Tesla push back the frontiers of “gigacasting”, the process it pioneered to cast large body parts for cars in one piece to save time and money. Until 2023, that is. TEI is now part of General Motors after agreeing a deal that may have flown under the radar but is a key part of the U.S. automaker’s strategy to make up ground on Tesla, four people familiar with the transaction said.
By snapping up a specialist in sand casting techniques that accelerated the development of Tesla’s gigacasting molds and allowed it to cast more complex components, GM has jump-started its own push to make cars more cheaply and efficiently at a time when Tesla is racing to roll out a $25,000 EV, the people said.
With TEI gone, Tesla is leaning more heavily on three other casting specialists it has used in Britain, Germany and Japan to develop the huge molds needed for the millions of cheaper EVs it plans to make in the coming decade, the four people said.
