伺服压机可编程滑块曲线显著改善高浮雕章填充。推荐三段法：第一段以 60% 名义吨位快速合模（速度 20–30 mm/s），第二段 85% 吨位低速（3–5 mm/s）压入主纹，第三段 100% 吨位保压 0.3–0.5 s。保压可抑制弹性回弹，飞边量比单段冲压减少约 30%，花纹棱线清晰度明显提升。
Programmable servo-press slide curves improve high-relief fill. Use a three-stroke plan: fast approach to 60% of nominal tonnage (20–30 mm/s), low-speed main coining at 85% (3–5 mm/s), then hold at 100% for 0.3–0.5 s. The dwell suppresses springback — flash drops about 30% versus single-stroke coining and relief edges come out visibly crisper. ---
