Such advice, for example how to set up blow molding machines, is not equipment specific and therefore ColorMatrix would always recommend using local or expert technicians in addition to following best practice points listed below; • Preforms should be conditioned for minimum 24 hours prior to blowing • Preforms should always be used in a FIFO manner (First In, First Out) • Octabins of preforms should be segregated and blown per resin type, i.e. not mixed with other resins • A preform traceability system should be in place such that any process upsets can be quickly followed up and corrected • Enhanced QC preform checking resources for bottle distribution, aesthetics and integrity should be on-hand during the performance optimization trials • Prior to any process optimization, the blowing machine performance should be verified as being within normal i.e. accepted standard ranges and all important components and control features are working satisfactorily. Maximum speed output should be attainable prior to any ‘recipe’ setting trials Copyright © 2020, Avient Corporation.
