573: Computer Simulation of the Rotational Moulding of Plastics
Wright, E.J and Crawford, R.J School of Mechanical & Manufacturing Eng., The Queen’s University of Belfast Northern Ireland, BT9 5AH
This paper describes the development of a computer simulation for the rotational moulding of plastics. Two separate aspects of the process – the kinematics of the mould rotation and the heat transfer to the plastic powder – are modelled separately and then combined into a complete simulation. The simulation is capable of reading CAD files of real rotomoulded components, and variables such as speeds, speed ratios, material bulk density, etc can be set by the user. The program will then predict and display the wall thickness distribution in the moulded article.
