以 30–60 W 光纤激光在模具钢或青铜模面直接雕刻纹理，扫描速度 800–1200 mm/s、单道功率 60%–80%，深度按道数累积（每道约 0.02–0.03 mm）。雕刻后用 800 目油石轻研去除熔渣重铸层，再以 5% 硝酸酒精轻蚀 10 秒统一表面光泽，可显著减少铸件粘模。
Engrave textures directly into tool-steel or bronze mould faces with a 30–60 W fibre laser at 800–1200 mm/s and 60%–80% single-pass power; depth accumulates about 0.02–0.03 mm per pass. After engraving, remove the recast layer with an 800-grit stone, then etch 10 s in 5% nitric-alcohol to unify lustre—this markedly reduces casting sticking. ---
