Investigation of the influence of mold rotational speed on the cast wall thickness in the rotational molding process

This paper presents the rotational molding process. The general principles of this polymer processing technology have been described. The main applications have been introduced and leading advantages and typical disadvantages of rotational molding process have been discussed. Based on the conducted experimental tests, the influ¬ence of changing one selected technological parameter, which characterized rotational molding process, on selected geometrical features of the polymer cast has been deter¬mined. Rotational mold’s speed around axes was changed and a thickness of cast walls has been measured. Laboratory test stand, processing properties of polymer, also test program and experimental test methodology have been described
