Why do many automobile enterprises in Tianjin like to punch with servo presses?

Hello, I have done a lot of press-fitting equipment in the auto parts industry. The automobile industry has high requirements for products, and the failure rate of products requires one in a million. For products that need to be press-fitted, whether the pressure suddenly changes or exceeds the threshold during the press-fitting process, so it is necessary to record the pressure feedback during the press-fitting process and trace it back, that is, the relationship between displacement and pressure during the press-fitting process. Servo presses can feed back these data, and even some servo presses can generate pressure charts.
