QUB PhD Researcher presents at Rotomoulding Conference in Goa

In January, QUB researcher Jitendra Seregar presented his research on “The Advanced Simulation of the Rotational Moulding Process” during the Society of Asian Rotomoulders (STAR) Annual Conference in Goa, India.  He, along with colleagues from QUB, also visited the local university BITS-Pilani Goa campus, toured the rotomoulding lab facilities there and discussed about future collaboration with institute.

The main aim of Jitendra’s project is to develop advanced computational models for the simulation of rotomoulded thermoplastic parts.  The simulation study is focused on; (1) direct tool heat transfer; (2) polymer powder flow, and; (3) shrinkage and warpage prediction.  The computational model development will help in investigating controlled heating of the mould, reduce energy requirement and improve product quality of rotomoulded products.  Rapid cooling can be achieved by natural air-cooling, forced internal air/mist/water cooling and forced air/water cooling techniques.  The numerical simulation study will help in understanding heat transfer rate/coefficients and related reduction in cooling time.  Predicting shrinkage and warpage helps in avoiding potential defects in parts moulded.  Thus, improving productivity and product quality of parts being rotomoulded.  Jitendra’s simulation work is expected to provide optimum process parameters.
