The packaging production process involves several steps. The following stages were identified as defective processes:
Inner Box Die-cutting and Waste Removal
Inner Box Gluing and Forming
Assembly and Full Inspection
Packing
Shipment
Root Cause: During the corrugated paper mounting process of the inner box, misalignment occurred. Although the die-cutting machine was adjusted correctly, defective products were mixed with good ones and defects appeared after cutting.
Outflow Reason: Assembly workers overlooked the misalignment, and final inspection along with OQC failed to detect the issue, leading to shipment of defective products.
Root Cause: Friction between the box sleeve surface and copy paper during transportation resulted in glossy marks.
Outflow Reason: Neither final inspection nor OQC identified the glossy print defects, which were subsequently delivered to the client.
YUTO Technology implemented immediate and long-term improvement measures to eliminate recurrence.
