Abstract
A new variotherm injection moulding process in which electric heating and water cooling are used to dynamically change the temperature of the mould is reported. The feasibility and temperature response of the system are evaluated through numerical simulation and the simulation results used in the design of a mould for a 32-inch liquid crystal display panel. A variotherm injection moulding line is constructed to verify the simulation results and to examine the effect of the new variotherm injection moulding technology on part quality. 21 refs.
