Two optimisation problems are formulated for an improvement of the effectiveness and productivity of pultrusion processes, preserving the quality of pultruded profiles, and taking into account an ambient industrial shop temperature and requirements of the process technologists. For a solution of these new problems, an optimisation methodology, using the designed computer experiments and response surface technique, is developed. The effects of room temperature and curing allowed behind the die exit are investigated in relation to the reduction of energy consumption and increase of the pull speed. More accurate and realistic process optimisation is achieved with the temperature control strategy executed by the heaters switch-on and -off operations. An application of non-direct optimisation methodology has allowed to develop interactive technological maps on the basis of an accessible to all Excel code for the technologists working in industrial shops. As an example, demonstrating an effectiveness of the developed methodology and utilisation of an interactive technological map, optimisation of real pultrusion process, producing in one time two rod profiles with ears, is carried out.
