Quality Inspection Report for PVC Foam Board in Ningbo, Zhejiang
Date of Inspection: April 6, 2025
1. Introduction
Our professional quality control (QC) team was commissioned by an importer of PVC foam sheets based in Puerto Rico to conduct a thorough inspection of their PVC foam board order at a mouldings factory in Ningbo, Zhejiang. The purpose of this inspection was to ensure that the products met the client’s stringent quality requirements before shipment.
2. Scope of Inspection
The inspection covered both visual (appearance) defects and internal (physical) quality parameters of the PVC foam sheets. Our QC team performed on-site checks at the factory and conducted laboratory tests to evaluate key performance metrics.
3. QC Team’s Professional Skills & Competence
Our team demonstrated exceptional expertise in:
- Material Knowledge: Deep understanding of PVC foam board standards and industry specifications.
- Precision Testing: Accurate execution of laboratory tests for physical properties.
- Defect Identification: Sharp detection of both visible and hidden flaws.
- Communication: Clear reporting and coordination with the factory to address non-conformities.
4. Identified Defects & Non-Conformities
4.1 Visual/Appearance Defects:
- Surface Scratches & Dents: Irregularities caused during handling or production.
- Uneven Edges: Poor cutting precision leading to inconsistent board dimensions.
- Color Inconsistencies: Visible batch-to-batch variations beyond acceptable tolerances.
- Bubbles & Delamination: Air trapped between layers, compromising structural integrity.
4.2 Internal Quality Failures (Lab Test Results):
- Density: Below the client’s specified range, affecting durability.
- Hardness: Insufficient resistance to indentation.
- Static Bending Strength & Elastic Modulus: Subpar mechanical performance under stress.
- Color Deviation (ΔE): Exceeded allowable limits, impacting aesthetic uniformity.
5. Client Decision & Corrective Actions
Due to the critical non-conformities, the client has requested the factory to reinitiate production under stricter quality oversight. Our QC team will conduct a re-inspection upon completion of the new batch to verify compliance.
6. Confidentiality & Publication
This report is published on our website with the client’s explicit consent. All sensitive information (client/supplier names, order details) has been redacted to adhere to confidentiality agreements.
7. Conclusion
Our inspection underscores the importance of rigorous quality control in PVC foam board manufacturing. The proactive approach of our QC team ensured defects were identified early, safeguarding the client’s interests. We remain committed to delivering transparent, professional, and actionable quality assessments.
