Numerical Studies of the Phase Change and Warpage under Various Process Conditions for Rotational Molding
The analysis of heat transfer in the rotational molding (rotomolding) process is a non-linear multi-dimensional problem. Using the two-dimensional (2-D) model from Lim and Ianakiev [13] the proposed phase-change algorithm, warpage formation, thermal distribution in the warped part, cycle time prediction and other key thermal properties have been investigated. The phase-change algorithm has decreased the computational non-linearity, while maintaining the level of accuracy. Additional useful observations and predictions are also presented from the warpage simulations.
