Contemporary Design: Drawn Coffee & Tea Ware
当代咖啡与茶器深冲设计应用
标签：咖啡, 茶器, 设计应用, 案例, 小批量
精品咖啡器具品牌近年用深冲替代旋压做铜制拉杆壶与奶缸：0.8 mm 紫铜卷料一道拉成 φ70 mm、H/D 0.9 的杯身，底部圆角 R6 保证导流，壁厚 0.65–0.75 mm。相比旋压，深冲效率高 5 倍且同心度 <0.05 mm，适合每批 500 只以上。设计端流行"拉深面留原色、口部旋切留刀纹"的半成品语言，与手工锻造系列形成价格分层（冲制 45–60 欧元 vs 锻制 120 欧元以上）。
Specialty coffee brands now deep-draw copper pitchers and milk jugs instead of spinning: 0.8 mm copper drawn in one pass to φ70 mm at H/D 0.9, R6 base radius for pour control, wall 0.65–0.75 mm. Drawing is 5× faster than spinning with roundness <0.05 mm, suiting runs of 500+. Designers keep the as-drawn face raw with lathe-turned rim marks, layering price tiers against hand-forged lines (45–60 EUR vs 120 EUR+). ---
