Quality Control Inspection Report for SPC Flooring in Hanoi, Vietnam
Inspection Date: March 6, 2025
Location: Hanoi, Vietnam
Product: SPC (Stone Plastic Composite) Flooring
Client: A U.S.-based SPC Flooring Importer (Name withheld per confidentiality agreement)
1. Introduction
Our professional quality control (QC) team was commissioned by a U.S. importer to conduct a thorough inspection of SPC flooring at a manufacturing facility in Hanoi, Vietnam. The objective was to ensure that the products met the client’s stringent quality requirements before shipment. The inspection covered both visual defects and functional performance tests in the factory’s laboratory.
2. QC Team’s Expertise & Professionalism
Our QC inspectors possess extensive experience in flooring product inspections, with in-depth knowledge of SPC flooring manufacturing processes, international quality standards, and testing protocols. During this inspection, the team demonstrated:
- Technical proficiency in identifying material and workmanship defects.
- Meticulous attention to detail in assessing both aesthetic and structural integrity.
- Strict adherence to ASTM & client-specific quality benchmarks during lab testing.
- Professional communication with factory personnel to document findings accurately.
3. Key Quality Issues Identified
A. Visual & Surface Defects
- Scratches & Dents: Multiple panels exhibited surface abrasions due to improper handling during production.
- Color Inconsistency: Some batches had noticeable shade variations, indicating poor color mixing or coating application.
- Edge Chipping: Rough or uneven edges were observed, likely from imprecise cutting.
- Surface Blemishes: Minor pits and uneven textures were found, suggesting extrusion or pressing defects.
B. Structural & Functional Defects
- Warping & Bowing: Several planks showed slight curvature, which could affect installation stability.
- Poor Locking System Fit: During test assembly, some interlocking mechanisms were either too tight (causing difficulty in joining) or too loose (leading to gaps).
- Delamination Risk: In lab tests, a few samples showed weak bonding between the wear layer and the core, raising concerns about long-term durability.
C. Lab Test Failures (Physical Performance)
- Thickness Deviation: Some samples did not meet the specified thickness tolerance (±0.2mm).
- Insufficient Wear Resistance: Abrasion tests revealed subpar scratch resistance in certain batches.
- Low Impact Resistance: Drop tests resulted in cracks on a few samples, indicating brittleness.
- Dimensional Instability: After water immersion, some planks expanded beyond acceptable limits.
4. Client Decision & Corrective Actions
Due to the severity of the defects, the client has:
- Rejected the current batch and requested the factory to restart production.
- Required a re-inspection by our team upon completion of the new batch.
5. Conclusion
Our QC team’s rigorous inspection ensured that only compliant products reach the client, safeguarding their brand reputation. The findings underscore the importance of in-process quality checks and pre-shipment inspections for SPC flooring.
