Beschreibung
Zusammenfassung:	A method of accelerating the cooling of articles made from polymeric particles, such as thermoplastic particles, in which compacted particles are subjected to a heat effect so that selected regions thereof are preferentially heated and the remaining regions thereof remain substantially unheated to produce a heterogeneous temperature distribution within the particles. When the heating effect is removed the preferentially heated regions cool in a rapid fashion by heat transfer therefrom to the unheated regions thereof.
