PM3透气钢其实是一类特殊的粉末冶金多孔材料，因材料中存在无数个细微的小孔，孔径约在7-10цm，镶在塑胶模中可帮助解决排气问题，故又名“透气钢”。

PM3透气钢透气钢特点

1. 比重小,比强度大。2.能量吸收性好。3.制振效果好。4.比表面积大。有1/4的组织是通孔。

PM3透气钢特性

  1.降低注射压力,减少成型和保压时间。2.降低和消除成型件的内应力,防止产品的变形和曲翘。3.表面皮纹的塑料零件,由于高温高压产生的亮光皮纹,能解决要求亚光的表面。4.由于模具分型面的紧密配合,可以解决开模困难等情况。解决通常利用顶针、镶件等无法提供足够表面区域以容纳可能产生的大量气体等诸多问题,避免了利用分型面或其他排气系统而产生的飞边及其他瑕疵。5.可使由于浇口偏位、壁厚不匀、壁薄产品等较难成型问题得到解决和缓解。6.由于成型材料高温产生的气体和模具腔内快速聚压产生的烧焦、流痕、缺料、吸气造成的零件变形等缺陷能得到充分解决。7.提高成型生产效率,节约生产成本。   因此,于注塑模具之适当位置镶上PM-35透气钢,由气体所形成的注塑问题,可以完全清除,使成型加工更加完美。
