INSPECTION 17 PETplanet Insider Vol. 24 No. 09/23 www.petpla.net Luca noted, the alternative is to make hand measurements with a magnetic gauge for thickness. The Gawis 4D, with its non-contact thickness measurement, eliminates the need to do thickness manually, which takes a lot of time. This goes for large containers as well as the very small. “We need to measure both thickness and thickness variation over and around the preform or bottle wall. Material distribution analysis takes time.” The Gawis 4D captures hundreds of measurements over the length and around the circumference of the preform. This makes it quite simple to measure thickness variation as well as other attributes such as concentricity, min/max and average in a single measurement sequence. On the Gawis 4D this is performed in conjunction with dimensional measurements, in less than one minute. Additionally, the Gawis 4D is industry 4.0 compatible making it possible to easily communicate with other devices and share data. Testing, testing, testing… One of the defining aspects of Sipa is the wide portfolio of products that includes beverage bottles, preforms, jars, small and large containers and even, detergent containers. Testing and measuring are not limited to new machines and moulds. Nowadays, most of the projects coming through the Sipa lab are pretty challenging, including lightweighting or new resins testing, with the focus on sustainability. Taking measurements is not as easy as people might think. “Everything is extraordinary” – every week is a new challenge and any savings in time is welcome. AutoJob Since time and accuracy are of the essence in this facility, taking into account the wide variety of products, one of the biggest challenges typically associated with automated measurement systems is the amount of time it takes to program each job. The Gawis 4D addresses this handily with a patented feature called AutoJob. With this feature, the operator simply selects the AutoJob mode and the work of locating and identifying finish features is performed automatically and incorporated into the job within a matter of seconds. The operator can adjust the selection, add control limits, and incorporate additional measurements as necessary. AutoJob can be used to create a new job or identify an existing job template, through template matching, that most closely matches the container. Template matching, another feature associated with AutoJob, finds the closest match of a scanned bottle finish to a job template already in the template library, or published standard template. The work in this lab goes well beyond qualifying
