The invention relates to a method for inspecting a container (2) made of plastic material obtained by molding, the method comprising:a step of capturing a thermal image of the container (2) on leaving the mold (31);a step of characterization of the container (2), in which a rule for acceptance or rejection of the quality of the container (2) is applied, as a function of the thermal image of the container (2) on leaving the mold (31),wherein, prior to the characterization step, the method comprises a step of identification, on the thermal image, of at least critical zone corresponding to a structural part of the container (2),and wherein the acceptance rule is parameterized to consider a container (2) as acceptable if, for each identified critical zone, the temperature of the container is lower than a predetermined threshold temperature.
