Giga Press is a unique machine that has given Tesla a great competitive advantage. The machine casts a one-piece front and rear end for Model Y construction, which offers significant advantages both in production and in the performance of the vehicle. Canadian company Exco Technologies Limited said it is partnering with Tesla to develop Giga Press, according to a statement from its CEO, Darren Kirk, on Thursday during its earnings call.
