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.
超薄冷轧钢/铝合金薄板弯曲后容易翘曲和回弹；我们采用定制弯曲模具+分段压力成型工艺，精确控制回弹值，保证成型后平整度在严格范围内。
对于不规则的多弯折叠支架，传统加工容易导致尺寸超出公差；我们预编程的数控弯曲补偿技术可将整体公差保持在±0.1mm以内，满足内部电子模块的高精度装配要求。
靠近弯曲线的孔在成型后往往会发生位置偏移；我们采用预弯曲定位孔布局+成型后精细校准，以确保孔中心对齐，螺钉装配顺畅，无需强行配合。
狭窄的深弯槽容易出现边缘塌陷和毛刺；我们采用特殊的小尺寸弯头，并进行全面的后磨去毛刺处理，以保持边缘整齐无划痕，便于内部元件安装。
自有激光切割、数控精密折弯、攻丝、铆接、研磨、表面处理车间，无外包流程，成本控制更佳，生产全程可追溯。
多年来积累了电动汽车充电器和储能装置内部支架和外壳的深度加工经验，熟悉电力设备的内部装配逻辑、散热布局和抗干扰结构设计，能够提供 DFM 结构优化建议，以降低您的装配故障率。
对每一批次进行首件检验、过程尺寸检验和成品全抽样测量，有效避免批量生产中的尺寸波动，为长期订单合作提供稳定的交货计划。
接受基于图纸/样品的 OEM & ODM 定制，可调节材料（SPCC、SGCC、铝、不锈钢）、厚度、弯曲结构、孔位置、表面处理（粉末涂层、拉丝、钝化），并提供定制标志标记。
