Rectangular Frame Panel With Sheet Metal Chassis Panel and Flanged Outer Edges

Panel flatness and hole true position are the governing callouts for a rectangular flanged sheet metal chassis panel; flatness outside tolerance causes the chassis to rock against the mounting rails and introduces uneven fastener preload at each corner, while hole position error prevents the panel from aligning with enclosure frame apertures at assembly. Chongqing Jiangjin Changfeng Precision Machining (Chongqing, established 2001, Degan Industrial Park) mills this rectangular frame sheet metal chassis panel with flanged outer edges via CNC milling and boring & milling at their approximately 20,000 m² Chongqing facility, with panel flatness, hole true position, and flange height checked using your drawing as reference at initial sample inspection. ISO 9001 certification governs traceability for aerospace, automotive, and military sheet metal chassis panel applications. For quoting, share your drawing with flatness requirement, hole true position, flange dimensions, and material specification so our Chongqing facility can prepare pricing.
