The invention relates to a method and a device for the secondary treatment and the cooling of preforms ( 10 ) once they have been removed from the open mould halves ( 18, 9 ) of an injection moulding machine. The preforms are removed from the open moulds ( 18, 9 ) while still hot, by means of water-cooled cooling sleeves ( 21 ) of a removal device ( 11 ), and are subjected to intensive cooling during the duration of an injection moulding cycle. Both the entire inner side and the entire outer side of the blow-moulded part ( 10 ) are subjected to intensive cooling. Secondary cooling is then carried out, the duration thereof being equal to a multiple of the duration of an injection moulding cycle. After being removed from the casting moulds, the preforms are dynamically introduced into the cooling sleeves ( 21 ) until they fully touch the walls thereof. The inner cooling is carried out in a time-delayed manner.
