Quality Control Process

At Fytop, quality is embedded in every stage of production. Our ISO 9001-certified quality management system ensures that every component—from raw material to final shipment—meets the highest standards of precision, consistency, and reliability. Here’s how we safeguard your projects: 

1. Pre-Production Control 
- Material Traceability  
  ✓ Verify material certificates (composition, hardness, heat treatment status) from qualified suppliers.  
  ✓ Assign unique batch numbers to all metal/plastic raw materials (aluminum 6061, SUS303, POM, etc.).  

-Process Planning 
  ✓ DFM review with clients to optimize tolerances (±0.02mm standard / ±0.01mm upon request).  
  ✓ Tooling and fixture design approved by senior technicians before mass production.  
2. In-Process Monitoring  
- First-Article Approval  
  ✓ Full inspection of the first 3 pieces using calibrated tools:  
    - Vernier calipers (0-300mm)  
    - Micrometers (±0.005mm accuracy)  
    - Height gauges & surface roughness testers (Ra 0.8-3.2μm standard)  
  ✓ Documented inspection report shared via email/Message for client confirmation.  - Scheduled Process Audits 
  ✓ Hourly dimensional checks on 5% of batch output (prioritizing critical features).  
  ✓ Tool wear compensation logs updated every 4 hours for key CNC machines.  
  ✓ Visual inspection for burrs, scratches, and surface defects (LED workbench lighting).  
3. Final Inspection & Delivery 
- Dimensional Sampling
  ✓ AQL 1.0 sampling plan (GB/T 2828.1-2012) for general batches.  
  ✓ 100% inspection for high-risk features (threads, mating surfaces, ±0.01mm tolerances).  

- - Functional & Durability Tests
  ✓ Basic salt spray test (12-24hrs neutral salt spray) for anodized/plated parts.  
  ✓ Assembly trial with client-provided mating components (if applicable).  

Traceability & Documentation  
  ✓ Each shipment includes:  
    - Inspection report with key dimensions  
    - Material certificates (upon request)  
    - Photos of packaged goods  
  ✓ Retain samples for 2 years (stored in labeled moisture-proof boxes). 

4. Corrective & Preventive Actions  
- Defect Analysis  
  ✓ Weekly quality meetings to review RMA cases – categorize defects (tooling, programming, human error).  
  ✓ Implement countermeasures within 72hrs (e.g., fixture optimization, operator re-training).  

- Client Feedback Loop  
  ✓ Monthly quality performance reports shared with key accounts (defect rate, on-time delivery).  

  ✓ Annual process upgrade based on client audit suggestions.  

Why Trust Us?
- Transparent Metrics
  ✓ ≤0.8% defect rate (industry median: 2.5%) with 98% on-time delivery.  
  ✓ 24-hour response for quality complaints.  

- Staff Accountability 
  ✓ QC technicians with 5+ years’ experience in precision machining.  
  ✓ "Zero Hidden Defect" bonus policy for production teams.  

- Balanced Investment 
  ✓ Annual calibration of all measurement tools (CNAS-certified labs).  
  ✓ Progressive upgrade of key equipment.
