Frequently Asked Questions
常见问题
What types of industrial control enclosures can SanJun produce?三骏能做哪些工业控制外壳？
We produce PLC control cabinets, floor-standing electrical enclosures, wall-mounted control boxes, server chassis, instrument housings and DIN-rail mounted panels for factory automation.我们生产 PLC 控制柜、落地式电气柜、壁挂控制箱、服务器外壳、仪器仪表壳体和 DIN 导轨安装面板，用于工厂自动化。
What tolerances can you hold for precision control cabinet parts?精密控制柜零件能达到什么精度？
Typical tolerances are ±0.1 mm for bending and ±0.05 mm for critical mounting features. Higher precision is available for mating panels, slide rails and connector cutouts.折弯一般 ±0.1 mm，关键安装位 ±0.05 mm；面板配合、滑轨和接口开孔可提供更高精度。
Can you add DIN rails, mounting plates and cable ducts?可以加装 DIN 导轨、安装板和线槽吗？
Yes. We integrate zinc-plated or aluminum mounting plates, DIN 35 mm rails, cable ducts, busbar systems and grounding bars according to your electrical layout.可以。我们可按电气布局集成镀锌或铝板安装底板、DIN 35 mm 导轨、线槽、铜排系统和接地排。
What surface treatments are used for industrial control cabinets?工业控制柜常用哪些表面处理？
Common treatments include powder coating (RAL colors), galvanized steel, zinc plating, anodizing and anti-corrosion primers for outdoor or harsh industrial environments.常用喷粉（RAL 色卡）、镀锌板、镀锌、阳极氧化和户外/恶劣工业环境用防腐底漆。
What is the MOQ for custom control cabinet prototypes?定制控制柜原型起订量多少？
Our MOQ is 1 piece for prototype samples, with no mold cost for sheet-metal parts. This lets you verify fit and function before scaling to production.原型样品起订量 1 件，钣金件无需开模，便于您在量产前验证装配与功能。
