Quality Isn't Expensive. It's Priceless. Here's Our 3-Step Quality Assurance Process.
✓In the aluminum industry, consistency is everything.
One bad batch can ruin your production schedule, damage your reputation, and cost thousands in rework.
That's why at Jiahe Aluminum, quality isn't just a department - it's our culture.
🔬 STEP 1: Incoming Material Inspection (Raw Aluminum Coils)
Every coil we receive undergoes:
• Chemical composition analysis (spectrometer testing)
• Thickness and width verification
• Surface quality check (scratches, oxidation, stains)
• Mill Test Certificate (MTC) verification
📏 STEP 2: In-Process Quality Control (During Slitting)
Our operators monitor:
• Real-time dimensional checks (thickness, width, flatness)
• Edge quality inspection (burr-free, smooth edges)
• Visual defect detection (surface imperfections)
• Tension control (prevents coil deformation)
✅ STEP 3: Final Inspection & Certification (Before Shipment)
Every order includes:
• Complete dimensional inspection report
• Mechanical property testing (tensile strength, elongation, hardness)
• Surface quality verification
• Packaging inspection (seaworthy, moisture-proof)
• MTC (Mill Test Certificate) for full traceability
