①模具预热至 60–100 ℃ 并薄涂二硫化钼或蜡系脱模剂 ②退火坯料酒精脱脂并定位入阴模 ③慢速单次压印到底，保压 0.5–1 s ④顶出坯件 ⑤若有微翘曲用校平模轻压 ⑥滚光/抛光至镜面，再做旧或封护。禁止连续快速连击以免模温骤升崩模。

① preheat dies to 60–100 ℃ and thinly coat MoS₂ or wax release ② degrease the annealed blank and seat it in the female die ③ coin slowly to bottom in one hit, dwell 0.5–1 s ④ eject ⑤ if slightly warped, true on a flattening die ⑥ tumble/polish to mirror, then patinate or seal.
