Meaning
Quality control audits conducted before goods leave the manufacturing facility confirm that a batch of materials meets all contractual and regulatory requirements. For polymer manufacturers, pre-shipment compliance verification involves reviewing batch records, certificates of analysis, and test results for plasticizers and heavy metals. This verification ensures that only compliant resin lots are shipped to the injection molding company.
It prevents the costly return of non-compliant materials and protects the manufacturer from legal liability.
Verification Procedure
An inspector reviews the raw material records, inspects the packaging for proper labeling, and takes representative samples for laboratory testing. These tests may include measuring melt flow index, density, and volatile organic compounds. The lot is only released for shipment after all test results are verified.
Molding Risk Reduction
Using verified resins protects the molding facility from processing problems and part defects caused by inconsistent materials. It also guarantees that the molded parts will comply with food safety or medical regulations. This reduces the risk of finished product rejects during final inspection.
Documentation Package
The verification process results in a compliance package that accompanies the shipment. This package includes the certificate of analysis, the declaration of compliance, and any specific test reports. It is required for customs clearance in many markets.
