Abstract (en)
[origin: WO8200015A1] To produce frozen casting moulds or core boxes the binder is cooled till freezing at least partly before or during the moulding process. This allows the production rate to be increased to such a level that the working rate of automatic machines for the production of casting moulds and core boxes can be turned into full account.
Abstract (fr)
Pour produire des moules de coulee ou des boites a noyau solidifies le liant est refroidi jusqu'a obtenir une solidification au moins partielle avant ou pendant le moulage. Ceci permet d'augmenter la cadence de production jusqu'a un niveau tel que la capacite de travail des machines automatiques de production de moules de coulage et de boite a noyau puisse etre totalement utilisee.
