Rectangular Flat Panel with Machined Sheet Panel and Folded Edge Flanges

Aluminium alloy grade and face flatness tolerance together determine fit quality and anodising adhesion for a rectangular machined sheet panel with folded edge flanges; 6061-T6 suits automation brackets, drone structural panels, and monitoring equipment housings where anodised Type II provides corrosion protection at Ra ≤ 1.6 μm, while 5052-H32 is specified for marine-adjacent panels where formability at the flange bend is priority. Flange height uniformity also determines stack-up dimension at the assembly joint. Dongguan Tongshunda Precision Technology (Dongguan, Guangdong, established 2023) CNC-mills this rectangular flat machined sheet panel with folded edge flanges at their just under 2,000 m² Dongguan facility, with panel flatness, flange height, and hole true position verified per your drawing during first article review. Tongshunda serves aerospace, automation, drone, medical equipment, and robotics machined sheet panel applications on CNC milling equipment, boring & milling, and surface grinding. For quoting, share your drawing with panel flatness, flange height, hole positions, and aluminium grade so we can prepare a production detailed quote from our Dongguan team, active in military, drones, and battery.
