Common defects include wall thickness variations, surface blemishes, flash (excess plastic at seams), and poor transparency. These issues often arise from improper temperature control, inconsistent parison inflation, or mold misalignment. Advanced monitoring systems now allow real-time adjustments during production to maintain precision. Non-destructive testing methods, such as visual inspection, pressure testing, and dimensional analysis, help detect faults early. Automated vision systems further enhance quality assurance by identifying microscopic imperfections. Maintaining material consistency and mold cleanliness also plays a…
