INSPECTION 20 PET planet Insider Vol. 18 No. 03/17 www.petpla.net Fig.3: Cavity ID recognition of different fonts Collaborations Having built up and continuing to build relationships and partnerships with leading plastic bottle and preform manufacturers, Torus have created a rewarding collaborative environment. Two examples of such collaborations are the advanced burst testing (see fig. 4) developed in collaboration with ColorMatrix and the single operation top load & volume gauge. Fig.4: Torus B303 bottle burst tester Advanced bottle burst results ColorMatrix required detailed information regarding material perfor- mance; specifically volume expansion & material yield data. Working with ColorMatrix, the research and devel- opment team understood the impor- tance of why these features would be beneficial and created a specialised solution. The collaboration resulted in new features such as the stress strain curve shown in figure 5. Integrated top load & volume gauge With guidance from the team at Logoplaste, Torus developed a single operation top load & volume gauge, see figure 6. The system works by the user loading a bottle just once and performing both tests automati- cally. Torus researched the market and found that current systems were slow, with insufficient support. In many cases manual volume measurements were still being performed, drain- ing manpower and often inducing measurement errors. The B304 top load & volume gauge combines both tests into one robust system, reducing operator intervention and increasing part traceability, saving testing time and improving accuracy. The complete solution It is important to understand the inspection process from start to finish. Beginning with the requirement and working with the customer to develop a reliable gauge, but also assisting with results analysis. To facilitate this, Torus offer statistical process control soft- ware, known as SPCXplorer. SPCX- plorer can be configured for new Torus gauges and/or existing third party laboratory equipment.
