Meaning
A batch of raw materials or molded parts fails to meet the specified dimensional, chemical, or performance criteria agreed in the purchase order. Rejecting a non-compliant shipment protects the manufacturing line from using defective resin that could damage injection molding equipment. This action triggers a formal supplier corrective action request.
Production Risk
Processing out-of-specification polymers can lead to severe defects like short shots, flashing, or structural weakness in the finished part. When a non-compliant shipment reaches the factory floor, it must be quarantined immediately to prevent accidental use. This isolation prevents the contamination of clean silos and molding bins.
Financial Consequence
Molding operations suffer from lost productivity and potential shipping delays when incoming materials are rejected. The presence of a non-compliant shipment often forces the molder to reallocate production time and reschedule downstream assembly operations. Costs associated with returning the defective material and sourcing replacements are borne by the supplier.
Quality Resolution
Resolving raw material discrepancies requires a robust agreement on testing methods and reference samples. Upon identifying a non-compliant shipment, the quality department compiles metrology reports and laboratory test data to support the rejection claim. The supplier must then analyze the root cause of the variation and provide a certified replacement batch.
This corrective process ensures that the replacement material conforms to the original technical specification.
