Therefore, if the foreign plants adopt plastic extrusion molding for over-voltage crosslinked polythene cable, they currently adopt "plastic extrusion sulfuration by layers" method.

因此国外厂家对超高压交联聚乙烯电缆如果采用“挤塑模铸法”，目前均采取“分层次挤塑硫化”工艺方式。

The injection molding period f the thick wall fming may be reduced by over 60%, improving plastics' fluidity filling effect.

使厚壁成型注塑周期可降低60%以上，增强塑料的流动性及填充效果。

The same principle applies here as to stripping any internal undercut i. e. the molding must be free to expand during ejection to permit the molded undercut to ride over the restriction on the core.

相同的原理用到这儿关于推出任何内部模型凹穴，也就是说零件在顶出时必须能自由扩张答应形成的模型凹穴通过型芯的约束。
