CNC Machining for High Altitude Balloon Payloads



The frontier of nearspace exploration is being unlocked by highaltitude balloons, carrying sophisticated payloads to the stratosphere. For the engineers and researchers designing these missions, every gram and every millimeter counts. The extreme environment—characterized by intense UV radiation, temperatures plunging to 60°C, and nearvacuum pressures—demands payload components that are not only incredibly lightweight and durable but also precisionengineered to perform flawlessly. This is where advanced CNC machining becomes a critical enabler for success.

CNC (Computer Numerical Control) machining is the ideal manufacturing process for highaltitude balloon payloads. It allows for the creation of complex, highstrength parts from a wide range of materials perfectly suited for the stratosphere.

Material Excellence: We machine components from highperformance engineering plastics like PEEK and Ultem, which offer excellent strengthtoweight ratios and low outgassing properties, crucial for vacuum conditions. For structural frames and brackets, aluminum alloys such as 6061 and 7075 are preferred for their machinability and formidable strength without adding significant mass.
Unmatched Precision: Payloads often include sensitive sensors, communication equipment, and optical systems that require perfect alignment. CNC machining produces parts with tight tolerances, ensuring that housings, mounts, and interfaces fit together perfectly, guaranteeing the integrity of your experimental data.
Lightweighting & Integration: Through sophisticated designformanufacturing (DFM), we can help optimize your parts, creating intricate geometries that remove unnecessary material and integrate multiple functions into a single, robust component. This reduces assembly time and potential failure points while minimizing the overall weight to extend flight duration.

From custom sensor enclosures and antenna mounts to complex camera housings and deployment mechanism components, our fullservice CNC machining provides the reliability and precision your mission depends on. We understand that a payload's success hinges on the quality of its construction.
