Aerospace Rapid Prototyping & Precision Manufacturing
Prototyping and rapid precision manufacturing are crucial elements of the aerospace product design and development cycle. AS Prototypes delivers comprehensive, multi-process manufacturing solutions—integrating simultaneous 5-axis CNC machining, DMLS superalloy 3D printing, precision sheet metal fabrication, rapid tooling, and polyurethane vacuum casting for commercial aviation, satellite constellations, defense UAVs, and propulsion systems. From monolithic airframe bulkheads to thin-walled turbine blisks and cockpit avionics housings, our in-house engineering team guarantees tight tolerances down to ±0.005 mm, full raw material MTR traceability, and on-demand Zeiss CMM inspection.

Inspect precision macro geometries, tolerances, and flight subsystem applications across our specialized aerospace manufacturing cells:
5-Axis CNC Milling for Structural Airframes & Impellers
Specializing in monolithic hog-outs from solid billet, deep-pocket rib structures, and thin-walled aerodynamic airfoils. By executing simultaneous multi-axis continuous toolpaths, we eliminate datum re-clamping errors and guarantee true-position tolerances down to ±0.005 mm.
Direct Metal Laser Sintering (DMLS) for Flight Hardware
Enabling internal conformal cooling channels, mass-optimized generative lattices, and complex consolidated assemblies that cannot be produced via traditional subtractive cutting. Fully dense aerospace alloys sintered under high-purity argon chambers.
Avionics Sheet Metal Laser Cutting & Bending
High-precision fiber laser cutting (accuracy ±0.05 mm), multi-axis CNC hydraulic press brakes, and TIG/laser micro-welding for flight-ready sheet metal assemblies. We fabricate lightweight aluminum chassis, heat dissipation shrouds, and battery bay support structures.
Rapid Tooling & Molding for Flight-Grade Polymers
High-performance thermoplastic components produced via precision rapid bridge tooling and injection molding. We specialize in processing virgin PEEK, glass-reinforced PEEK-GF30, and Ultem 1000 for critical aerospace applications demanding extreme chemical resistance, dielectric insulation, and zero outgassing in vacuum space environments.
Polyurethane Vacuum Casting for Cabin Interiors
For low-volume aircraft cabin mockups, flight deck control interfaces, and avionics housings (5 to 50 units), polyurethane vacuum casting delivers cost-effective, production-grade fidelity without hefty steel tooling expenses. Utilizes flame-retardant polyurethane resins matching aerospace cosmetic standards.
Optical Diamond Turning & Surface Finishing
Comprehensive in-house finishing lines supporting Single-Point Diamond Turning (SPDT), chemical vapor polishing for transparent PC/ABS cockpit display indicators, and MIL-A-8625 Type III hard anodizing (25–50 μm) for extreme aerospace environmental durability.
3. Aerospace DFM: Machining Dynamics & Thin-Wall Control
Flight-critical manufacturing demands proactive design-for-manufacturability coordination between CAM cutter dynamics, residual stresses, and coating growth:
Symmetrical Step-Roughing & Thin-Wall Chatter Control (Down to 0.8 mm)
Deep cavity airframe ribs down to 0.8mm–1.2mm wall thickness are prone to acoustic resonance and chatter. Our engineering team deploys balanced dynamic trochoidal toolpaths and symmetrical step-roughing on 5-axis CNC machining centers. By alternating cutting passes across opposing walls and utilizing high-pressure through-spindle coolant (70 bar) to dissipate thermal gradients, we eliminate cutting harmonics and guarantee dimensional tolerances down to ±0.008 mm.
Residual Stress Relief & Thermal Management for Superalloys
Machining high-stress alloys like Titanium Ti-6Al-4V, 15-5PH/17-4PH, and Inconel 718 generates immense localized heat. We strictly source pre-stretched 7075-T651 billets and execute intermediate stress-relief annealing between roughing and finishing stages. High-pressure through-spindle chilled micro-lubrication prevents heat buildup, eliminating subsurface work hardening and guaranteeing surface finishes down to Ra 0.4 μm.
Precision Thread Masking & Mil-Spec Coating Growth Compensation
Type III Hard Anodizing builds up 50% on exterior surfaces and penetrates 50% into aluminum. A 50 μm hardcoat contracts inner bore diameters by 50 μm. Our programmers calculate exact CAM pre-machining offset compensations: bores are intentionally pre-machined oversized so that post-treatment parts contract to nominal ±0.005 mm dimensions, while M2–M24 threads are shielded with tapered silicone plugs.
