ABSTRACT:
A large-sized and heavy part (1) of plastic material is injection molded. Localized zones are created in which the thermal conductance of the part (1) is higher in the surface impressions (10) at the mold ejectors for the removal of the part after it has been molded. In a preferred embodiment, the outer surface of the part (1) has, at the surface impressions (10), clusters of closed-bottom pits (13) formed by grids of mini-ribs (11) and (12) arranged perpendicularly with respect to each other. The thickness of the part varies from a maximum value (S1) at the periphery of the cavity to a minimum value (S2) at the bottom of a substantial number of the pits (13).
