Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
这款定制多媒体音频控制面板采用优质 6063 铝合金，通过专业的钣金激光穿孔加工工艺精密制造而成，由领先的音频和电子设备硬件一站式钣金加工工厂 SanJun Hardware 独家生产。
大多数音频设备采购者都面临着设计能力不足、复杂不规则的孔位布局要求、激光切割后薄铝板变形、孔边缘粗糙以及表面处理不一致等问题。三骏五金凭借成熟的技术和免费的全周期设计支持，全面解决了所有这些行业痛点。
无需客户提供图纸文件。只需告知您的设备尺寸、按键/界面布局、外观要求和使用场景；我们的专业机械工程师将免费完成CAD/3D图纸设计，并可无限次修改直至您确认，从而大幅缩短您的前期开发时间和设计成本。
我们能够解决大多数小型工厂无法处理的棘手机械加工难题：
支持全套生产流程：激光穿孔切割 → 数控折弯 → 攻丝 → 表面处理（拉丝、喷砂、黑/金阳极氧化、丝网印刷logo） → 铆接组装。所有工序均在自有车间完成，无外包，质量稳定，交货周期更短。
孔位公差±0.02mm，平面度0.1mm以内，完美匹配放大器、混音器、多媒体扬声器、会议音频主机组装标准。
可定制尺寸、孔型、表面颜色、logo印刷；支持原型小批量试订单和大批量生产。
