The classic core part of the four station hot press machine for bare battery cells is the rotary hot pressing mechanism, which uses an upper and lower pressure plate heating method and a temperature controller to control the temperature and heat the battery. At the same time, dual cylinder output is used to achieve pressure boosting effect for hot pressing, and a one out four simultaneous hot pressing method is adopted to improve equipment efficiency Battery hot pressing is the process of shaping bare cells by setting reasonable time, temperature, and pressure, controlling the thickness of the bare cells to prevent relative displacement of the positive and negative electrodes.
