Purpose: The main purpose of carry out research was estimate the influence thermal conditions of the mould on properties of injection moulded parts. Design/methodology/approach: The properties of structure and mechanical properties of injection moulding parts were determined by many factors. One of them is thermal conditions of tool. Injection mould can be heated or cooling during the process and its depend which kind of polymer we produced and what properties we going to obtain. A few different cooling mould systems were presented in the article and disadvantages and advantages of each of them. Findings: The impact of thermal condition (cooling rate, mould temperature) on the structure and physical properties of injection moulded parts were present. Research limitations/implications: Research was limited to a few thermoplastics polymers. Practical implications: Received and presented results are useful from the point of the view of industrial applications and they are able to contribute to improvement parts obtained using injection moulding technology. Originality/value: Very original microscopic research carry out during cooling stage of polymer and crystallization process.
