Purpose: The project shows the results of researches of the flow of polymer materials during the filling the mould. The main purpose of carry out research was estimate the influence thermal conditions of the mould on the temperature profile of injection moulded parts. Design/methodology/approach: The most important issues like injection moulding process and the conditions of this process are covered in article. Moreover, the computer system used in the process of material conversion like Cadmould-3D by SIMCON is analysed in this work.The simulation of the injection moulding process is done with the variety of different parameters of conversion. The aim of this simulation was to present the distribution of the temperature in the moulded piece. The cooling system of the injection moulding form was taken into analysis during this simulation. Findings: The results of researches enabled documentation of specific occurrences in injectionmolding process of polymer materials and comparison of those results with the results of numericalcalculations. Research limitations/implications: Research was limited to a three thermoplastics polymers. Carrying out of simulation of injection process require data input concerning geometrical parameters of moulded piece, conditions of injection process,properties of processed plastic and data referring to injection machine into calculating program. Practical implications: The investigation delivered information about temperature profile of moulded piece in thermostatic mould form, what can be useful in practice, when selecting the material for good quality parts. Originality/value: In result of carried out computer simulations, extensive research material was obtained, which was subjected into detailed analysis in order to its adequate interpretation.
