Machined Plate Disc with Circular Mounting Flange Plate and Countersunk Through-Holes

Material hardness and corrosion resistance determine whether this circular mounting flange plate holds its flange OD tolerance and countersunk hole depth under operational load without deformation; making material specification the first checkpoint for this part. Flange OD and countersunk hole depth are verified against your print during first article review; flange OD governs mating pilot fit, and hole depth determines fastener head seating. Both are documented on the inspection certificate before release. Machined at Welltop's Dongguan facility under ISO 9001 controls with CNC milling and turning, the disc body and countersunk through-holes are produced from your latest drawing release. Hole true position and face flatness are verified during in-process sampling. Applications span automotive structural flanges, aerospace sub-assembly mounts, and OEM equipment plate assemblies. The production site covers an estimated 4,000 m². Production covers oil & gas, shipbuilding, and drones applications. Supply your drawing detailing for a proposal from our Dongguan facility.
