From CAD to Part: The Process

Honyo Prototype China CNC Prototyping Process Overview

Honyo Prototype delivers precision CNC prototyping services from our ISO 9001-certified facilities in Dongguan, China. Our streamlined workflow ensures rapid turnaround without compromising quality, specifically designed for B2B engineering teams requiring functional prototypes. Below is a detailed technical breakdown of each phase.

Upload CAD
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, X_T, or native SOLIDWORKS/Creo formats) via our secure online portal. Our system automatically validates file integrity, checks for unit consistency (mm/inch), and identifies potential geometry errors like non-manifold edges or missing surfaces. All data is encrypted per ISO 27001 standards, with strict NDA enforcement. This phase typically completes within 15 minutes of submission.

AI-Powered Quoting
Immediately after CAD validation, our proprietary AI quoting engine analyzes 15+ technical parameters: material utilization efficiency, feature complexity (e.g., thin walls <0.5mm, deep cavities >10:1 aspect ratio), machine time estimation, and secondary operation requirements. The engine cross-references real-time data from 12,000+ historical projects and current workshop capacity. Clients receive a formal quotation within 2 business hours, including:
Detailed cost breakdown (machining, material, finishing)
Lead time commitment (standard: 5-7 business days)
Recommended material substitutions if requested grade is non-optimal

DFM Analysis and Engineering Review
Unlike automated-only competitors, Honyo integrates AI-driven DFM checks with mandatory human engineering validation. Our CNC specialists perform:
Automated Checks: Wall thickness validation, tool access verification, tolerance stack-up analysis
Manual Engineering Review: Critical feature assessment (e.g., datum alignment, chamfer requirements), manufacturability scoring against ISO 2768-mK standards

DFM Check Type	Parameters Verified	Resolution Method
Geometric Feasibility	Undercuts, draft angles, hole depth-to-diameter ratios	Toolpath simulation in Mastercam
Tolerance Validation	GD&T callouts vs. achievable Cpk (≥1.33)	CMM capability mapping
Material Optimization	Thermal stability, chip evacuation risk	Material science database cross-reference

Clients receive a formal DFM report within 24 hours, highlighting actionable improvements with engineering rationale. Zero-cost revisions are permitted at this stage.

Production Execution
Approved designs move to our Dongguan facility equipped with 85+ CNC centers (DMG MORI, HAAS, MAKINO). Key production protocols:
Material certification: All metals (6061-T6, 7075, SS304) and engineering plastics (Delrin, Ultem 1010) include mill test reports
Process control: In-process inspections at 25%/75% completion using Zeiss CMMs; real-time tool wear monitoring via Renishaw probes
Traceability: Laser-etched part IDs linked to digital work orders showing machine parameters (RPM, feed rate, coolant pressure)

Complex assemblies undergo sub-assembly validation before final finishing (anodizing, powder coating, or precision plating per ASTM standards).

Delivery and Quality Assurance
All prototypes undergo final inspection against AS9102 aerospace standards (even for non-aerospace parts), including:
Full FAI report with dimensional results (±0.025mm typical tolerance)
Surface roughness verification (Ra 0.8µm standard)
Material certificate reconciliation

Parts ship globally via DDP terms with temperature-controlled logistics for sensitive materials. Every shipment includes:
Digital quality package (PDF inspection reports, CMM data)
Physical documentation (certificate of conformance, material certs)
On-time delivery tracking with 98.7% on-time rate (2023 performance data)

Honyo’s process eliminates traditional prototyping bottlenecks through engineered validation points, ensuring first-article approval rates exceed 92% for qualified designs. This integrated approach reduces time-to-test by 30-50% compared to conventional quoting-to-ship workflows.
