Laser-cut Blanks and Auto-feed Coining Lines
激光切割坯料与自动上料压印线

小批量异形章坯用光纤激光切割比冲裁更经济：1.5 mm 黄铜切割速度 2.5–3.5 m/min，切缝约 0.1 mm、毛刺少，免去开模费；切后坯料经滚筒研磨 30 min 去毛刺与热影响色。压印端配振动盘自动上料，轨道按坯料厚度 +0.2 mm 调隙，理料速度 40–60 枚/min。该组合把 500 枚以下异形纪念章的交期从开模 10 天压到 48 h，已成为打样与众筹订单的主流路线。
For short-run odd-shaped blanks, fibre-laser cutting beats blanking dies: on 1.5 mm brass, cut at 2.5–3.5 m/min with a 0.1 mm kerf and minimal burr—no tooling cost—then tumble the blanks 30 min to remove burrs and heat tint. Feed the press from a vibratory bowl with the track set to blank thickness +0.2 mm, orienting 40–60 pieces/min. The combination cuts lead time on sub-500-piece medals from 10 days of toolmaking to 48 h, now the default route for proofs and crowdfunded orders.
