BOTTLE MAKING 23 PET planet Insider Vol. 19 No. 12/18 www.petpla.net BOTTLE MAKING 23 This proven process ensures there are no prototyping difficulties or ‘trial- and-error’ guess work. The software algorithms draw on validated sci- entific data, the vast experience in accurately predicting material per- formance, and the unique material model to accurately represent the PET behaviour in SBM. Key outputs of the simulation include 3-D and axi- symmetric simulation, bottle section weights and thickness distribution which provide a detailed analysis of the effects of processing conditions on material distribution. Finally, using all of the vali- dated data in previous steps, Step 6 involves using the simulation to explore the process window and pro- duce an optimum preform to meet the in-service performance requirements of the bottle. With deep understanding of this science behind polymers, BMT claim that they can engineer, test, simulate and design the new plastic bottles and preforms of the future with confidence, be it from PET resins, PET blends, recycled PET, additives, bio-plastics or bio-materials. With the experience, knowledge and tools, they can help facilitate this seismic shift in the indus- try, creating environmental, economic and social benefits for all, states the company. www.bmt-ni.com SDWHQWV UHVHDUFKHUV DQG WHFKQLFLDQV LQVWDOOHG SODQWV EUDQFKHV ZRUOGZLGH ,I ZH KDGQêW JRQH VR IDU ZH ZRXOGQêW EH VR QHDU <RXU IXWXUH VHHQ IURP QHDU Figure 5: Visual Simulation Output
