The forming process for the high-strength, steel-base modified polyformaldehyde composite material in five-laver structure is to melt modified polyformaldehyde by heating and roll to make the melt polyformaldehyde permeate into the gaps gaps between the large-grained spherical copper powder and screw copper nails.

四层结构的钢基铜塑复合材料的成型过程，是将改性聚甲醛加热熔化，经轧制，使熔融的聚甲醛渗透到大颗粒球形铜粉的间隙中，解决了三层材料复合过程中，熔融的聚甲醛水平流动性强过垂直方向的渗透性，造成了结合强度低的缺陷，使聚甲醛层与铜粉及基体结合更牢固，提高了其承载和抗剪切的能力。
