In the spring of 2022, in the testing workshop of GAC Toyota Motor Co., Ltd., equipment from China, Japan, and Germany were engaged in a war without gunpowder. In the extreme test of the third month, our equipment worked continuously for 18 hours in a high temperature environment of 40 ℃ without any frequency reduction. After passing Toyota's unique devil test, the procurement director said at the summary meeting, 'What we need is not the most expensive equipment, but the partner who understands Toyota's production philosophy the most.'. This cooperation has become a typical case of equipment procurement in Toyota's "Asian Supply Chain White Paper".
