Performs high-precision inspection of transparent PET preforms, including the top-seal, the bottom, the body and the thread area. The inspection includes identification of colour defects, diameter and wall thickness measurements, perpendicularity, weight and colour. This SACMI X-RAY Inspector can read the number of cavities moulded in the neck of the preform to produce statistics based on this number. This new version of the machine introduces the patented inspection module that applies innovative Artificial Intelligence tools to the inspection with Polarised Light. Thanks to an extremely fast and guided format change, the operator will be able to switch from one preform to another with different diameters, lengths and colours in a few simple steps, without the use of tools.
