An inspection system to improve the quality of glass containers for pharmaceutical use has been developed by SPAMI, part of the Stevanato Group.
It uses quality control technologies to screen the glass tubing on arrival at the plant as well as the final product.
A visual inspection system (NoVIS) enables continuous temperature measurement, while a digital image processing system called CLEANER is able to detect and remove defects in the glass as small as a few microns in the final product.
The fully integrated process machinery provides measurement of glass tube diameter, wall thickness, and temperature using infrared pyrometers (pyrometer annealing control) for total quality control, and motorised burners provide close control of their positioning.
The use of this system gives Stevanato an advantage in quality over other vial manufacturers, says the company.
