Inspection of plastic bottles

In the pharmaceutical industry, the quality control process includes the inspection of both the target product (e.g. tablets, capsules) and the packaging. Manufacturing defects in packaging can directly affect the properties of the drug product, which is why thorough quality control is so important. In the last few years, we have deployed several vision inspection stations for white HDPE bottles at a leading plastics manufacturer. Scope of Inspection:
  • black spots (burns, inclusions) white spots (impurities, inclusions)
  • bottle outline (dents, deformations, etc.)
  • flashing (m.in. on the neck)
  • bottle weld
  • neck shape
The vision system has been built into the production line and has an automatic ejection process for defective parts. The system capacity is 10 bottles per second, minimum defect size 0.5 mm.
