ENGLISH ABSTRACT: This thesis represents the impact of the conformal cooling on the performance of injection moulds for the packaging industry. An existing, commonly used, off the shelf plastic part for the packaging industry, was selected for this study. Five different cooling layouts were simulated on the software package Moldflow Plastics Adviser TM to identify the shortcomings of conventional cooling. The simulation went through an iteration process until the optimum cooling and part quality was achieved. A comparative experiment was done to determine the difference in performance of injection moulding using conventional I conformal cooling layouts. The manufacture of two different mould designs is explained. Modern manufacturing methods, which are able to produce complex conformal cooling designs, are also discussed.

AFRIKAANSE OPSOMMING: Hierdie tesis verteenwoordig die impak van. vormh9lte-verkoeling op die gedrag van inspuitgietvorms vir die verpakkingsindustrie. 'n Bestaande, algemeen beskikbare plastiek artikel van die verpakkingsindustrie is vir hierdie studie gebruik. Die sagtewareprogram Moldflow Plastics Adviser™ is gebruik om vyf verskillende verkoelingsuitlegte te simuleer om sodoende die tekortkominge van konvensionele verkoelingsmetodes te identifiseer. Die simulasies is deur middel. van 'n herhaalproses gedoen om optimale verkoeling en onderdeelkwaliteit te verseker. 'n Vergelykende eksperiment is uitgevoer om die verskil in verrigting tydens inspuitgiet wanneer onderskeidelik konvensionele- en vormholte-verkoelingsmetodes gebruik word, vas te stel. Die vervaardiging van twee verskillende gietvormontwerpe word verduidelik. Moderne vervaardigingsmetodes wat die vermoe het om komplekse vormholte-verkoelingsontwerpe te produseer, word bespreek.
