A review of the effect of changes in moulding parameters on polymeric composite injection moulding is
presented in this paper. The emphasis of this work is on the use of short fibre reinforced polymer composite
in the injection moulding process. The behaviours of fibres that influence the performance of the injection
moulding process, like fibre orientation and distribution, fibre concentration and fibre length, are initially
reviewed. The effects of mould design such as the effect of gate design, the effect of the runner system and
the effect of cooling channels are then studied. The effects of processing parameters, particularly the effect
of injection speed, are also discussed. Finally the use of mould flow simulation software is reviewed.
