Abstract: 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.

Abstract: Method and apparatus for cooling a heated mold (12, 14, 16) of a device (10) for blow-molding thermoplastic containers, the device including: a mold (12, 14, 16) having an internal face which delimits a molding cavity (18) and which includes an external face (20, 28) which surrounds the molding cavity (18); heating elements for heating the mold to a determined temperature and which are deactivated when the cooling method is implemented; characterized in that the mold (12, 14, 16) is cooled by circulating heat-transfer fluid directly in contact with the external face (20, 28) thereof.
