Aluminium Casting with Three Bolt Tubular Flange Casting and Central Cylindrical Tube

Three bolt tubular flange casting in aluminium alloy, die-cast with a central cylindrical tube and three-point bolt mounting pattern for secure pipe or shaft retention. Controlled material class, surface finish, and tolerance range ensure consistent seating and alignment under service loads. Specified for HVAC duct mounting brackets, conveyor roller bearing housings, and automotive exhaust hanger flanges where lightweight strength and corrosion resistance are required. Cast and secondary-machined at our ISO 9001–certified Ningbo facility (established 2002), supporting bicycle, fastener, and furniture project production. Die casting and CNC machining performed in-house for dimensional control. Provide a signed-off CAD file or reference sample with bolt-hole PCD, tube bore diameter, and surface finish requirement for a three bolt tubular flange casting quotation. Lead time quoted per batch, with cost set by tolerance window and inspection depth.
