PNT的辊压机采用了对辊方式, 对涂布完的铝箔和铜箔进行辊压后减小基材厚度,增加了密度,有效的控制了长度和宽度偏差。
预热辊和压辊的温度设定范围为从常温到最高 150℃(±1.5℃),通过特殊装置和独有的技术有效的解决了运行中产生褶皱的现象。

Roll Press Machine can reduces the thickness and increase the density of Al/Cu foil coated with electrode compound by using cooling and heating pressing roll.
In addition, it can adjust the temperature of pre-heating roll and press roll between room temperature and 150℃. Above all things, PNT has know-how to prevent wrinkles .
