Architectural Hardware: Coined Plaques and Door Plates
建筑五金中的精压铭牌与门牌
标签：建筑五金, 铭牌, 门牌, 精压
精压在建筑五金中的应用以铭牌与门牌为主：2.0–3.0 mm 黄铜板以 150–300 t 压出 0.8–1.2 mm 浮雕文字，深浮雕款加一次精压保证棱线清晰；压后 CNC 铣外轮廓与安装孔，做旧采用硫化钾喷淋加局部拉丝。工程验收关注平面度 ≤0.5 mm/m 与封护层耐候（中性盐雾 500 h）。高端酒店与历史建筑标识常指定手工修边，单块溢价可达机制牌 3 倍，是压印厂的高毛利产品线。
In architectural hardware, coining lives on plaques and door plates: 2.0–3.0 mm brass struck at 150–300 t raises 0.8–1.2 mm lettering, with a second coining stroke for deep relief edges; outline and fixing holes are CNC-milled afterwards, aged by K₂S spray with local brushing. Acceptance keys on flatness ≤0.5 mm/m and sealer durability (500 h neutral salt spray). Luxury hotels and heritage buildings often specify hand-dressed edges, commanding up to 3× machine-made pricing—a high-margin line for coining shops.
