FIELD: manufacture of hollow articles from synthetic-base polymer by blow moulding. SUBSTANCE: blank is released from the mould for injection moulding at the instant, when the shape of this blank remains unchanged due to the presence of surface layer formed on the surface as a result of quenching, and when internal cooling is not yet completed and the inner temperature remains high; and orientation blow moulding of the blank is carried out during the time period until the blank surface temperature, which rises and the influence of its inner temperature, has not yet attained its maximum value. EFFECT: facilitated procedure. 6 cl, 9 dwg, 4 tbl
