CNC Machining, Die Casting and Forging for LEO Satellite Components

The rapid growth of low Earth orbit satellite communications, Earth observation and satellite IoT applications is increasing the demand for lightweight, modular and repeatable manufacturing.

Satellite metal components must withstand launch vibration and shock while meeting strict requirements for weight, dimensional accuracy, thermal management and production consistency.

CNC machining is suitable for prototypes, customized parts, precision assemblies and critical mechanical interfaces.

Typical applications include:

• CubeSat frames, baseplates and structural panels
• Electronic, RF and communication module housings
• Antenna bases, waveguides and payload brackets
• Heat spreaders, cold plates and thermal interface parts
• Reaction-wheel housings, motor mounts and bearing supports
• Deployment-mechanism components
• Thruster mounts, valve bodies and propulsion manifolds

Common materials include 6061 and 7075 aluminum, titanium, stainless steel and copper alloys.

Depending on the material, geometry, wall thickness and inspection method, critical features may be manufactured to a dimensional tolerance level of approximately ±0.01 mm. Precision control may also cover flatness, concentricity, perpendicularity and true position.

For satellite constellations with stable production volumes, aluminum die casting can integrate cooling fins, mounting bosses, reinforcing ribs and cable channels into a single component.

Potential applications include:

• Electronic and communication housings
• Motor and actuator housings
• Sensor protection enclosures
• Secondary structural parts
• Ground-support and test equipment

Critical sealing surfaces, locating holes, threads and assembly interfaces can be finished by CNC machining after casting. This combination supports production efficiency while maintaining precision where it is required.

Suitability for flight hardware must still be evaluated according to component criticality, material properties, internal porosity and customer qualification requirements.

Forging is suitable for components that require higher strength and resistance to vibration or repeated mechanical loads.

Near-net-shape forgings combined with CNC finishing can reduce material waste and machining time while maintaining strength and critical dimensional accuracy.

Satellite component manufacturing requires more than dimensional compliance. Important manufacturing controls may include:

• Thin-wall deformation control
• Dimensional and geometric tolerance management
• Material certification and batch traceability
• CMM dimensional inspection
• First article inspection
• Manufacturing and inspection records
• Vacuum-compatible materials and finishes
• Anodizing, conversion coating and nickel plating
• Prototype-to-production process development

Whether for low-Earth-orbit (LEO) satellites, communication equipment, UAVs, or other aerospace applications, we can evaluate and recommend the most suitable CNC machining, die-casting, or forging solution based on your 2D drawings, 3D models, material specifications, tolerance requirements, and production quantities.
