... generated a series of design of experiments in an attempt to evaluate and measure the benefits of conformal cooling for injection moulding. He presented an overview of the mould design methodology, ... performance The advent of computer-aided engineering (CAE) technol- ogy for plastic injection moulding provides a large support to injection mould design. Injection mould design simula- tion modules ... geometric approximation of cooling passageway with a specific offset distance d. The new offset surface will identify the location of the cooling passageway of the mould cavity. The new offset surface is then offset...
