Mold for forming containers from blanks of plastic material. The mold includes a shell delimiting a cavity with the impression of a container extending around a central axis, and a system for heating the shell. The heating system includes at least one set of different resistive elements that are superimposed substantially parallel to the central axis and of similar topology, the heating system being arranged to dissipate a different thermal energy at each resistive element of a same set.
