模具晒纹处理是指在模具表面刻出规定的纹路，以改善模具的外观和加强模具表面的耐磨性。这种技术通常用于铸造模具、压力模具和注塑模具等。
英文中，模具晒纹处理可以称为 "mold texturing" 或 "mold texturizing"。
下面是一些英文例句及其中文翻译：
"The mold texturing process involves creating a pattern on the surface of the mold using a variety of techniques, such as etching or engraving."（模具晒纹处理包括使用各种技术（如蚀刻或雕刻）在模具表面制作图案。）
"Mold texturing is often used to improve the appearance of plastic parts, as well as to increase the wear resistance of the mold."（模具晒纹通常用于改善塑料零件的外观，也用于增加模具的耐磨性。）
"The texture on the mold surface can be achieved through various methods, such as electroforming, laser etching, or mechanical engraving."（模具表面的纹路可以通过多种方法实现，如电铸、激光蚀刻或机械雕刻。）
