某电动车厂以 H65 黄铜带（0.6 mm）辊压细密编织纹用于内饰饰条，辊压后经拉丝与阳极氧化定色。关键控制点：带材张力 0.8–1.2 kN 防止波浪、辊面温度低于 50℃ 避免油渍碳化、纹理方向与装配光带呈 45° 以弱化反光不均。月产 12 万件，废品率控制在 1.5% 以内。
An EV maker rolls H65 brass strip (0.6 mm) with a fine weave pattern for interior trim, followed by brushing and anodising to fix the colour. Key controls: strip tension 0.8–1.2 kN to prevent waviness, roller temperature below 50℃ to avoid oil carbonising, and the pattern set 45° to the assembly sight line to even out reflections. Monthly output 120 k pieces with scrap under 1.5%. ---
