Manufacturers of glass vials now use quality control technologies in screening the glass tubing both ways – on arrival at the plant as well as the pre-release of the final glass vial product. The system includes a visual inspection system, another system for continuous temperature measurement, and a digital image processing system called Cleaner. This method can detect and remove tiny defects in the glass, some as small as a few microns. This fully-integrated processing machinery gives out measurements of glass tube diameters, wall thickness, as well as temperature. This provides for total quality control and the motorized burners likewise providing close control of the positioning.
