Numerical study of profiled conformal cooling channels for cooling time reduction in injection mould tools

In injection moulding, cooling time for polymer and process thermal management are critical issues having key effects on process cycle times. In the conventional injection moulds, cooling channels have circular cross-section due to the manufacturing technique of drilling. In a circular channel, ther...
