Thermoforming is a manufacturing process widely used to produce thin thermoplastic parts from small blister packs to display AAA size batteries to large skylights and aircraft interior panels. In this paper was presented numerical simulation of the inflation phase of a thermoforming process under which a thin polymer sheet is deformed into a mould under the action of applied pressure. Two cases of blowing sheet were considered. In the first, preapproved on the basis of a constant sheet temperature (T = 150°C) examined the distribution of the container wall thickness. There has been excessive thinning (about 0,2mm) in the cup corners after forming. Also simulation it was made for other constant temperature (160, 170, 180, 190 and 200°C). On this basis, was made optimization of the sheet profile temperature (in range 150÷200°C) to remove excessive thinning. Noted was a significant effect of the initial sheet temperature distribution on the final wall thickness distribution in the considered container. The Ansys Polyflow procedure of optimizing the sheet temperature distribution allowed eliminating excessive thinning in the considered cup walls corners.
