将A1中得到的物料在滤网上进行过滤，得到糊状浆料；
A3：网布预处理
将网布放在压布机上进行微压，微压次数为5-10次，再把压好的网布放入切布机上进行边角切割，进而得到边角平整以及表面平直的网布；
A4：防电磁波辐射处理
将A2中所得到的浆料放在在模具中进行冷却，冷却完成后，采用切割机将半成品的防电磁波辐射材料的边角以及上下表面进行平直切割，使其得到边角平整以及表面平直的防电磁波辐射材料层；
A5：高温贴合金泊
将金泊放在网布以及防电磁波辐射材料层之间，再对网布以及防电磁波辐射材料层的外表面进行加热或者预热，在贴合压花装置处把三层同时贴合在一起，正面是一支压花钢辊，底面是橡胶，把将近熔融状态的网布、防电磁波辐射材料层以及金泊结合在一起，贴合压力为3Mpa，贴合温度为160℃，贴合辊速度为8m/min；
A6：压花
将A5得到的半成品复合膜材料采用压花机的压花辊进行上、下表面压花处理，得到印花后的复合膜材料，然后将印花后的复合膜材料经过冷却辊充分冷却定型，压花辊采用油压推动，油压调整在3-5Mpa；
A7：卷材包装处理
将A6得到的成品复合膜材料进行检验、卷成成品。
