All CNC medical parts are manufactured in a controlled environment with full traceability, adhering to ISO 13485 standards. First article inspection (FAI), CMM reporting, and visual inspection are standard for critical features. Tight tolerance features such as sealing surfaces, mating bores, and alignment interfaces are routinely held within ±0.0125 mm (±0.0005″) with process validation.
From CAD to Part: The Process
Honyo Prototype CNC Medical Parts Manufacturing Process Overview
Honyo Prototype delivers precision CNC medical components through a rigorously controlled workflow designed for regulatory compliance, speed, and zero-defect outcomes. Our process begins with CAD file submission and concludes with validated delivery, integrating AI-driven efficiency with stringent medical-grade quality protocols. Below is a technical breakdown of each phase.
CAD File Submission and Validation
Clients initiate the process by uploading native CAD files (STEP, IGES, Parasolid, or native SOLIDWORKS) via our secure customer portal. Our system performs automated geometry validation to verify file integrity, unit consistency, and manufacturability against baseline tolerances. Files failing validation trigger immediate client notification with specific error diagnostics, ensuring only fully compliant designs advance to quoting. This step eliminates 92% of upstream errors before engineering engagement.
AI-Powered Quoting Engine
Validated CAD data feeds into our proprietary AI quoting platform, which analyzes geometric complexity, material requirements (e.g., ISO 10993-certified PEEK, 316L stainless steel, or titanium), and tolerance stacks (including ultra-precise medical-specific GD&T callouts). The engine cross-references real-time machine capacity, material pricing, and historical production data to generate a formal quote within 2 business hours. Quotes include explicit process capability indices (Cp/Cpk ≥ 1.67 for critical features), secondary operation notes (e.g., passivation, electropolishing), and compliance documentation pathways (ISO 13485, FDA 21 CFR Part 820).
Medical-Grade DFM Analysis
Upon quote acceptance, our engineering team conducts a dual-phase Design for Manufacturability review. Phase 1 uses AI to flag high-risk geometries (e.g., thin walls <0.5mm, deep cavities with aspect ratios >10:1) against medical-specific failure modes. Phase 2 involves senior engineers performing manual DFM for regulatory alignment, focusing on:
| DFM Focus Area | Medical-Specific Checks | Risk Mitigation Example |
|---|---|---|
| Material Selection | Biocompatibility documentation traceability | Rejecting non-ASTM F138 stainless variants |
| Tolerance Allocation | Functional impact on assembly (e.g., catheter hubs) | Tightening positional tolerances by 30% |
| Surface Finish | Ra ≤ 0.8µm for implant contact zones | Recommending isotropic finishing processes |
| Cleanability | Elimination of crevices >0.1mm per FDA guidance | Redesigning undercuts to open geometries |
Client sign-off on DFM recommendations is mandatory before production, reducing iteration cycles by 70% versus industry averages.
Precision CNC Production
Approved designs enter our ISO 13485-certified cleanroom facility (Class 8 per ISO 14644-1) for machining. Key production protocols include:
Dedicated medical material lots with full mill certificates and traceability to heat/lot numbers
In-process verification via calibrated CMMs (0.0001″ accuracy) and optical comparators at defined stage gates
Real-time SPC monitoring of critical dimensions (e.g., thread pitch on bone screws) with automatic machine tool compensation
Mandatory first-article inspection per AS9102 standards, including material hardness testing and surface roughness validation
All non-conformances trigger immediate containment per our CAPA system, with root-cause analysis documented in the device history record.
Regulatory-Compliant Delivery
Final parts undergo 100% visual inspection under 10x magnification per AQL 0.65 Level II, followed by packaging in ISO 11607-compliant sterile barrier systems (where specified). Each shipment includes:
Signed Certificate of Conformance with material/test data
Complete DHR documentation package (traceable to CAD revision)
Sterilization validation reports (if applicable)
Dimensional inspection reports with actual vs. nominal values
Parts are shipped via temperature-controlled logistics with real-time GPS tracking, meeting agreed delivery windows at 99.2% reliability.
This end-to-end process ensures medical device components meet the highest safety and performance standards while accelerating time-to-market. Honyo Prototype’s integration of AI efficiency with deep medical manufacturing expertise eliminates traditional prototyping bottlenecks without compromising regulatory rigor.
