This thesis represents the results of a study for the use of conformal cooling in blow mould design. As a part of this, design case studies and comparative experiments were conducted to determine the difference in performance of blow moulds incorporating conventional cooling and those with conformal cooling. The cooling configurations are compared using simulation to identify the shortcomings of conventional cooling. In addition modern manufacturing methods able to manufacture complex conformal cooling designs, are evaluated. The relevant cooling principles are explained using mould designing handbooks as well as heat flow handbooks. The tie between them is made and the differences explained. The moulding cycles of injection as well as blow moulding process are explained and the applicable simulation software used in these fields is described.
