The quality of a rotationally molded part is highly dependent on its cooling rate, perhaps more so than its heating rate. A trade off between part quality and cycle times is often necessary to ensure economical feasibility. This paper presents an overview of the effect of cooling rate on final part quality. The temperature profile through the part wall during cooling is related to the part's mechanical properties, morphology, shape and general appearance. Six different mold cooling rates are investigated; they range from quiescent cooling (average 2C°/min) to water spray cooling (average 15C°/min).
