纪念币与徽章模具的纹理复制链条：原模（石膏或油泥浮雕）三维扫描（0.01 mm 级）→ 数字修型 → CNC 粗雕（球头刀 R3）+ 精雕（R0.5、步距 0.05 mm）加工 H13 模具钢，热处理至 HRC 50–52 后手工修整纹线；币面珠缘与 0.08 mm 防伪微字由激光补刻。国内深圳、温州徽章厂制作 45 mm 徽章钢模周期 3–5 天，寿命 8–15 万冲次；100–500 枚的小批量纪念币多用黄铜模液压成型，单模成本约 800–3000 元。
The medal and badge die chain: scan the original relief (plaster or oil clay) at 0.01 mm, retouch digitally, rough with R3 ball nose and finish with R0.5 at 0.05 mm stepover in H13 steel, harden to HRC 50–52 and dress the lines by hand; rim beading and 0.08 mm micro-lettering are laser-added. Shenzhen and Wenzhou badge plants turn a 45 mm die around in 3–5 days at 80,000–150,000 strikes; runs of 100–500 medals usually press in brass dies costing about ¥800–3,000.
