The present invention relates to an oven for preforms in plastic material, and particularly to a heating module to be used in said oven. Particularly, the present invention relates to a heating module (10) for ovens (1) for heating preforms (P), wherein said preforms (P) comprise a hollow body (B), a neck portion (C) and a flange (F) separating the hollow body (B) from the neck portion (C), said module (10) comprising a first side panel (25) and a second side panel (26), said side panels (25, 26) being mounted on a base plate (19) and mutually facing so as to create a gap (24) having such a shape and dimensions as to let a moving preform (P) passing therebetween, characterized in that said side panels (25, 26) comprise infrared lamps (23, 23') and first and second reflecting surfaces (21, 22) that are opposite and oriented so as to convey the thermal radiations on the preform surface, wherein the reflecting surfaces (22) of the second side panel (26) are configured so that the thermal radiations hit the preform surface with a low incidence angle and the reflecting surface (21c) of which in the first panel (25) is geometrized to reflect in a concentrated manner the energy emission of the lamp (23') immediately below the position (F) of the preform (P). |
