Injection moulding of two portion packages in IM Tops Module

Abstract: The task aims to investigate if it is possible to produce two portion packages with the same technical equipment and cycle time as for the 1000 ml Carton Bottle package. The assigner is MSc Pär Andersson at Tetra Pak. The work followed Ulrich and Eppingers “front-end process” and started with an interpretation of the client needs translated to target specifications. Several package concepts were designed in Pro Engineer and in a concept screening a concept was chosen. The chosen concept was then analysed in Moldflow and modified until a successful shape was found and the moulding parameters had been investigated properly. The necessary mould-tools were then designed and manufactured so that packages could be produced. After the tools had been assembled and tuned into a rig a testing period began but first a successful process parameter setup had to be found. When this setup had been found a continuity test, a weight test and a leakage test was made. In the end the final specifications were compared to the target specifications and the majority of the metrics were ideal. The conclusions from the task is that it is possible to injection compression mould two packages at the same time but the tools that were made for this project had some flaws.
