A recycling conveyor belt factory audit should verify more than production equipment and generic quality claims. This guide shows procurement and quality teams how to evaluate abrasion, oil and impact resistance against real waste-handling conditions, review relevant test evidence, trace QC from raw materials to shipment, identify supplier red flags, and prepare a more precise RFQ. It also explains why laboratory abrasion results, oil-resistance claims and “heavy-duty” descriptions should never be treated as standalone proof of field performance.
