Features of the process of rotational moulding of thermoplastics have been examined. Heat transfer processes have been analysed. The influence of the particle size of the polymer on the distribution of the processed material within the rotational mould and on the duration of transition of the polymer from the solid to the viscous flow state has been studied. The dependence of the thickness uniformity of an article of linear polyethylene on the rotational speed of the mould has been examined.
