理论上说，，尼龙塑料件加工当被点蚀或侵蚀过的模具外貌已准确仿制，，投射到制品外貌的光线会爆发漫反射。。。。。。因此，，外貌会泛起黯区。。。。。。对具有较少准确仿制的外貌，，漫反射征象就会获得控制进而制品外貌泛起好的光泽效果
与加工参数有关的缘故原由与改良步伐见下表：
1、保压太低 提高保压压力；；；；
2、保压时间太短 提高保压时间；；；；
3、模壁温度太低 提高模壁温度；；；；
4、熔料温度太低 提高熔体温度；；；；
与设计有关的缘故原由与改良步伐见下表：
1、模壁截面差别太大 提供更均一的模壁截面；；；；
2、质料积留过多或棱边尺寸过大 阻止质料积留过重或棱边尺寸过大；；；；
In theory, when the surface of the mold that has been pitting or eroded during the processing of nylon plastic parts has been accurately replicated, the light projected onto the surface of the product will undergo diffuse reflection. Therefore, there will be dark areas on the surface. For surfaces with less precise replication, diffuse reflection phenomenon will be controlled, resulting in a good gloss effect on the surface of the product
The reasons and improvement measures related to processing parameters are shown in the following table:
1. Raise the holding pressure if it is too low;
2. If the holding time is too short, increase the holding time;
3. Raise the mold wall temperature if it is too low;
4. Raise the melt temperature if the melt temperature is too low; The reasons and improvement measures related to design are shown in the following table:
1. The significant difference in mold wall cross-section provides a more uniform mold wall cross-section;
2. Excessive material accumulation or large edge size should be avoided to prevent excessive material accumulation or large edge size;
