Piezoelectric Sensor Frequency Response Calibration for Folding Boxboard Converting
Piezoelectric sensor frequency response calibration prevents amplitude distortion during high speed creasing by matching amplifier cutoff to rule strike transients.
Material Spoilage
Substrate Waste
Substrate losses occur when paper or board is damaged beyond use during the printing and die-cutting stages. Minimizing material spoilage is a primary goal for packaging converters seeking to lower their unit costs and reduce raw material consumption. This waste can occur during initial press setup, during run-time mechanical failures, or as a result of poor board quality that fails inspection.
Accurate tracking of where this paperboard is discarded allows plants to optimize their production settings.
Process Trigger
Modern packaging converters operate at extremely high speeds, where even a brief malfunction can ruin hundreds of carton sheets. Inconsistent substrate caliper or moisture can cause web breaks in gravure presses, leading to instant material spoilage of large quantities. Sheet-fed presses also generate waste if the suction feeders pick up multiple sheets at once, damaging both the paper and the blankets.
Additionally, errors in ink viscosity or coating chemistry can result in peeling or poor adhesion, forcing the rejection of entire batches. By using consistent, mill-certified boards and automated quality sensors, printing plants can reduce these sudden process failures.
Environmental Cost
Discarded paperboard increases the solid waste footprint of a converting facility. Efficient processing lowers material spoilage and improves the overall sustainability profile of the packaging run.
