In modern industrial supply chains, packaging is not just an outer shell but a vital link that directly influences the operating efficiency of automated assembly lines. As a trusted Tier 1 Vendor for Samsung and one of the Top 3 Smart Factories in 2023 in Vietnam, Tien Thanh A&E prioritizes product quality above all. To realize our commitment to maintaining a finished packaging defect rate below 0.8%, we strictly implement a three-level independent quality control system: IQC (Incoming Quality Control), PQC (Process Quality Control), and OQC (Outgoing Quality Control).

1. Incoming Quality Control (IQC)

The quality of a corrugated box begins with the raw paperboard reels. Tien Thanh A&E's IQC department is responsible for inspecting every imported paper batch:

• Grammage Verification (GSM): Measures the weight per square meter using electronic scales to ensure paper thickness aligns with B2B contract specifications.

• Moisture Content Testing: Employs infrared moisture meters to keep raw paperboard humidity within the standard 6% - 8% range. Dry paper breaks easily; wet paper reduces flute compression resistance.

• Visual Inspections: Defective, dented, or moisture-damaged paper rolls from transit are rejected immediately.

2. Process Quality Control (PQC)

During corrugating and printing runs, PQC staff and automated sensors monitor each production stage:

• BHS Q230 Corrugator Line Audits: Monitors starch adhesive bonding strength and preheater drum temperatures to ensure 3-ply, 5-ply, and 7-ply cardboard blanks achieve optimal rigidity.

• Flexo Color Match Controls: Compares print runs against signed Proof templates to prevent brand color shifts.

• Smart Poka-Yoke Sensors: Scans box blanks on the folding-gluing conveyor belt, automatically ejecting skewed or unglued items without interrupting production.

3. Outgoing Quality Control (OQC)

Prior to palletizing and loading onto transport trucks, finished packaging batches undergo rigorous physical stress tests in Tien Thanh A&E's independent laboratory:

• Bursting Strength Testing: Measures hydrostatic pressure resistance to verify that box faces will not puncture under impact.

• Edge Crush Test (ECT): Evaluates vertical stack load limits of the flutes, ensuring safety when stacking palletized electronics or heavy home appliances in export containers.

• Dimensional Accuracy Checks: Ensures crease and cut lines are precise to the millimeter so that boxes fold square on automated packing lines.

Conclusion & Contact

The independent IQC - PQC - OQC system combined with automation technology is the foundation that enables Tien Thanh A&E to maintain a defect rate below 0.8%, protecting B2B partners' product value and brand reputation.
