Purpose: The main purpose of the performed investigations was a multi-aspect analyzes of the blow moulding process in a mould which takes two-stage nature of the process and the occurrence of uncontrolled phenomena which influence the shape, size and quality of the products into consideration. Design/methodology/approach: The value for the Barus number for different dimensions of the nozzle gap and the distribution of the temperature field during blow moulding process have been determined; the product thickness profile has been defined; phenomena which occur during blowing stage have been registered. The investigations have been performed by means of the blow moulding machine of UFP-05 type by IPTS – Metalchem Toruń using the designed and prepared blow mould with the sight-glass made of polycarbonate. Findings: The performed investigations enabled the insight study of uncontrolled phenomena which occur during each individual stage of the process and they showed the dependencies between these phenomena and the process parameters. Moreover, the detailed analyses enabled to determine the influence of these parameters on the physical features and dimensions of the finished goods. Research limitations/implications: The continuation of the investigations with use of extended blow mould design equipped in polycarbonate sight-glass which enabled the determination of the influence of the structure and mould cavity dimensions on the finished product wall thickness seems to be justified. It would be also useful to design the station for the precise non-touch measurements of Barus effect which enabled, except the measurements of the external diameter, the measurements of the finished product wall thickness. Originality/value: The complex analysis of the blow moulding process was possible thanks to innovative and original approach to the experimental tests which enables e.g. the optical registration of the phenomena which occur during blow moulding process.
