Product Description

This custom CNC machined exhaust flange is designed for small gasoline powered fixed wing UAV engines, connecting the engine exhaust outlet to a matching pipe or silencer assembly. The exhaust port and bolt pattern must align with the engine interface, while the machined sealing land provides the specified surface for the exhaust gasket.

A suitable heat resistant stainless steel grade can withstand higher temperatures than many general purpose aluminum alloys, but the selected material must match the engine's exhaust temperature, thermal cycling and corrosion environment.

Before production, confirm the engine model, exhaust opening profile, bolt spacing, gasket dimensions, material grade and expected operating temperature. Port alignment, sealing face flatness and bolt hole locations should be checked against the engine drawing before the flange is installed.

    The engineering team reviewed our drawings carefully and asked practical questions before production. This helped clarify the tolerance, surface treatment, and assembly requirements. The finished parts met our expectations, and the communication process was efficient and professional. We would consider working with them again for future CNC projects
