PREFORM PRODUCTION 19 PET planet Insider Vol. 17 No. 11/16 www.petpla.net New preform design & prototyping service The quality of a bottle, its aesthetic appearance and its mechanical performance is also the result of a cor- rect preform design and of the quality of materials with which it was made. Often, a good design can be affected by the selection of a wrong preform or by the improper use of materials. PET Engineering created a new preform design & prototyping service that is said to ensure the right preform for every application and the perfect bottle for every preform. The service offers a perfect result thanks to the up to date technologies, e.g. HyPET Husky injection machine. The production of small and big batches is possible. The testing of material, additives and closures are realised separately. There is a guaranteed qual- ity thanks to the application quality tests during all production steps. Preform design The development of an ad hoc preform starts with the characterisa- tion of a current preform and con- tainer, but also with the mechanical and barrier performance levels that need to be achieved. The characterisation activities make it possible to have an overall picture of the current quality of the preform and bottle, thus to under- stand the improvements that can be achieved by implementing a new preform. Prototyping Once the stack has been created or modified PET Engineering will install it on a machine to prototype the preform. The prototype phase is designed to test the project by evaluating the perfor- mance of the container or containers that will be created with this preform. Manufacturing In this phase, PET Engineering designs and implements new stacks consisting of gate insert, grips, tap holder and cooling EOAT cups. Also the cavity, cooling tube and the tap were creating. Testing Once injected, the preforms are tested in the lab to verify their suitabil- ity with regards to required parameters. www.petengineering.com
