Abstract

Production cycle times for rotational molding are limited by the time required to heat up and cool down the mold and the product. Consequently, efforts have been made to enhance heat transfer to and from molds, ultimately reducing cycle times. The application of pins and roughened textures to molds has been investigated with several techniques being employed to predict the enhancement of heat transfer. To validate these predictions a series of rotomolding trials have been carried out using surface enhanced molds. Excellent cycle time reductions in the order of 30 and 20% have been achieved for the pin and roughness enhanced molds respectively, demonstrating the significant benefits mold exterior modification can provide to the industry.
