🔧 Inspection Notes for the Week:
- Interface dimensions: Strict tolerance of ±1mm (verified with vernier calipers).
- Duct coating thickness: ≥12μm (random sampling of 3 sections: 21.8μm, 20.0μm, 19.6μm).
- Flange flatness: Re-checked bolt-hole spacing with laser level for alignment accuracy.
💡 Why Do We Insist on “Over-Inspection”?
Every “perfect fit” during client installation is the result of 100 precision checks in our factory.
