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.
全套定制钣金加工解决方案
我们可以根据您的图纸或样品，全面定制整体长度、宽度、深度、孔位、端口数量和安装支架结构。精密数控折弯和激光切割，公差控制在±0.1mm以内，主板组装后无需二次修改，大大提高您的组装效率。
预留多界面布局，广泛兼容
标准机箱预留了充足的空间，可用于VGA、HDMI、串口、千兆以太网、USB、终端布线和射频天线接口。适用于POE监控主机、运动控制器、边缘网关、工业网关以及各种嵌入式工业计算机设备的集成。
坚固的SPCC钢结构和优质表面处理
采用加厚SPCC冷轧钢板结构，具有极强的抗压和抗变形能力。整个机柜经静电防锈粉末喷涂处理，耐刮擦、防尘、耐腐蚀，可适应严苛的工业车间、户外机柜和设备间等长期运行环境。机柜内部设有条形通风口，有效散热，防止主板过热。
壁挂式安装设计，节省空间
配备侧面固定安装支架，方便壁挂式安装，节省机柜空间，广泛用于自动化生产线、安防监控工程、智能交通、工业边缘计算和现场控制柜。
工厂直供，供货稳定。
无中间商加价，批量订单可享极具竞争力的出厂价。支持小批量试订单和大批量项目订单，提供完整的生产前样品确认、全过程来料及成品质量控制检验，确保批次外观和尺寸的一致性。我们为全球工业设备制造商和系统集成商提供一站式OEM和ODM服务，包括丝网印刷logo、颜色定制、表面处理升级等。
