大多数塑料成型模具
大多数塑料成型模具,除EMD加工外还需进行一定的切削加工和钳工修配。为延长切削刀具的使用寿命,提高切削性能,减少表面粗糙度,塑料模具用钢的硬度必须适当。
In most plastic moulds, besides EMD processing, certain cutting and fitter repairs are needed. In order to prolong the service life of cutting tools, improve cutting performance and reduce surface roughness, the hardness of steel for plastic die must be appropriate.
3、良好的抛光性能
3. Good polishing performance
高品质的塑料制品,要求型腔表面的粗糙度值小。例如,注塑模型腔表面粗糙度值要求小于Ra0.1~0.25的水平,光学面则要求Ra<0.01nm,型腔须进行抛光,减小表面粗糙度值。为此选用的钢材要求材料杂质少、组织微细均一、无纤维方向性、抛光时不应出现麻点或桔皮状缺陷。
For high quality plastic products, the surface roughness of the cavity is required to be small. For example, the surface roughness of injection  tuijian:gangmoju.07858.net www.qibiji58.com www.machine-com.com
www.qingmeiit.com.cn www.lgjianzhu.com www.baodingjiaju.com.cn hsjiaquan.75ix.co mold cavity is required to be less than Ra 0.1-0.25 level, while the optical surface is required to be Ra < 0.01 nm. The cavity must be polished to reduce the surface roughness. For this reason, the selected steel requires less impurities, uniform microstructure, no fiber orientation, and no pitting or orange peel defects in polishing
