Technical Capabilities

Honyo Prototype delivers precision custom aluminum parts manufactured in China using advanced 3-axis, 4-axis, and 5-axis CNC milling along with CNC turning processes. These capabilities support complex geometries, high repeatability, and tight tolerance requirements essential for aerospace, medical, automotive, and industrial applications. While aluminum is the primary material, we also support steel, ABS, and nylon for versatile prototyping and low-to-mid volume production runs.

|---|---|
| Machining Processes | 3-Axis, 4-Axis, and 5-Axis CNC Milling; CNC Turning (including mill-turn and live tooling) |
| Tolerance Capability | ±0.005 mm (±0.0002″) typical; tight tolerances down to ±0.002 mm (±0.0001″) achievable with process control |
| Surface Finish | As-machined: Ra 3.2 μm (125 μin); post-processing options include anodizing, bead blasting, powder coating, and polishing |
| Maximum Work Envelope (Milling) | 1200 x 600 x 500 mm (47″ x 23.6″ x 19.7″) for 3/4/5-axis platforms |
| Maximum Work Envelope (Turning) | Diameter up to 300 mm (11.8″), length up to 600 mm (23.6″) |
| Spindle Speed (Milling) | Up to 24,000 RPM for high-precision finishing |
| Positioning Accuracy (5-Axis) | ±0.003 mm (±0.00012″) with real-time probing and tool length compensation |
| Lead Time | 7–15 business days depending on complexity and finishing requirements |
Material Options and Applications
| Material | Typical Use Cases | Machinability | Notes |
|---|---|---|---|
| Aluminum (6061-T6, 7075-T6, 2024-T3, 5052) | Aerospace components, heat sinks, enclosures, automotive parts | Excellent; high strength-to-weight ratio, good thermal conductivity | Most requested material; supports anodizing and other surface treatments |
| Steel (4140, 1018, 17-4 PH Stainless) | High-strength mechanical parts, shafts, tooling, fixtures | Moderate to good; higher tool wear than aluminum | Capable of tight tolerances with optimized toolpaths |
| ABS (Acrylonitrile Butadiene Styrene) | Prototypes, housings, jigs, and functional testing | Excellent; low melting point, easy to machine | Ideal for non-metallic prototypes and low-stress applications |
| Nylon (PA6, PA66, GF-reinforced) | Gears, insulators, wear strips, low-friction components | Good; requires sharp tools and controlled feeds/speeds | Hygroscopic—must be conditioned pre-machining for precision work |
All parts are inspected using CMM, optical comparators, and digital micrometers to ensure dimensional compliance. Our ISO-compliant manufacturing system supports full traceability and first-article inspection (FAI) reporting upon request.
From CAD to Part: The Process

Honyo Prototype Custom Aluminum Parts Manufacturing Process
Honyo Prototype executes a streamlined, technology-driven workflow for custom aluminum parts manufacturing in China, ensuring precision, cost efficiency, and rapid turnaround. The process begins with secure CAD file submission and concludes with global delivery, integrating AI and engineering expertise at critical stages.
Upload CAD
Customers initiate the process by uploading native CAD files (STEP, IGES, SLDPRT, or Parasolid formats) via Honyo’s encrypted client portal. Our system validates file integrity and geometry compatibility with CNC machining, sheet metal fabrication, or casting capabilities. All data is protected under GDPR-compliant servers and NDA frameworks, with zero third-party access.
AI-Powered Quoting
Uploaded designs trigger our proprietary AI quoting engine, which analyzes 120+ geometric and material parameters to generate instant preliminary pricing. The algorithm factors in aluminum alloy grade (e.g., 6061-T6, 7075-T6), part complexity, tolerances (±0.005mm achievable), surface finish requirements, and machine time. Quotes include material waste calculations, setup costs, and expedited lead time options—all within 90 seconds. Human oversight by quoting engineers ensures contextual accuracy for non-standard features.
Engineering DFM Analysis
Every design undergoes mandatory Design for Manufacturing (DFM) review by Honyo’s senior manufacturing engineers. This phase identifies cost drivers and manufacturability risks before production. Key focus areas include:
| DFM Focus Area | Common Issue Identified | Honyo Resolution Approach |
|---|---|---|
| Wall Thickness | <1.5mm in cast parts | Recommend ribbing or alloy change |
| Tolerance Stack-Ups | Interfering GD&T callouts | Propose statistical tolerance analysis |
| Tool Access | Deep cavities >8:1 aspect ratio | Suggest EDM or multi-axis machining |
| Material Utilization | Excessive raw stock waste | Optimize nesting via HyperMill software |
Customers receive a detailed DFM report with actionable recommendations, cost-impact analysis, and 3D-marked revision suggestions. Approval requires explicit sign-off to proceed.
Production Execution
Approved designs move to Honyo’s ISO 9001-certified facilities in Dongguan. Aluminum parts are produced using:
5-axis CNC machining centers (Makino, DMG MORI) with sub-micron repeatability
Automated deburring and precision CMM inspection (Zeiss CONTURA)
In-process SPC monitoring for critical dimensions
All processes adhere to ASTM B209 and AMS 4027 standards. Customers access real-time production dashboards showing machine status, QC checkpoints, and material certifications.
Global Delivery Management
Completed parts undergo final FAI (First Article Inspection) with full dimensional reports. Honyo coordinates end-to-end logistics:
Packaging optimized for shock/vibration protection (ISTA 3A certified)
Customs documentation prepared for all major markets (including US FDA 21 CFR for medical)
Door-to-door tracking via DHL/FedEx with 72-hour shipment notifications
Typical lead times range from 7 days (prototype) to 15 days (low-volume production), with expedited options available. All shipments include material traceability certificates and PPAP Level 3 documentation upon request.
This integrated workflow reduces time-to-market by 40% compared to traditional quotation cycles while maintaining rigorous quality control. Honyo’s process eliminates engineering guesswork through data transparency, ensuring aluminum components meet functional requirements on the first build.
