PREFORM PRODUCTION 41 PET planet insider Vol. 15 No. 10/14 www.petpla.net Extrusion and Screw Control, part 15 Practical Guide to Injection Moulding of Preforms Quite a number of parameters need to be adjusted on a typical injection moulding machine, which may seem at first somewhat intimidating. After reading through Chapter 2, the reader should have a good under- standing of what the process should be to yield acceptable preforms. Putting this into practice is of course another matter. This chapter aims to translate the discussed theoretical concepts into concrete advice to run a machine on the floor. There will be some more theory to make concepts more understandable. PETplanet insider is publishing extracts from successive chapters of Ottmar Brandau’s “Bottles, Preforms and Closures”, which was first published by hbmedia. A newly revised version is reissued under the Else- vier imprint.
