Abstract

Metodo per produrre un complesso di modello di espanso da usare in un procedimento di colata con espanso a perdere, il metodo comprendendo le operazioni di fornire un complesso di modello di espanso che include una linea divisoria, ed una superficie che è intersecata dalla linea divisoria e che include una prima porzione di superficie ed una seconda porzione di superficie sfalsata dalla prima porzione di superficie in corrispondenza della linea divisoria, e livellare la superficie in modo che la prima porzione di superficie non sia sfalsata dalla seconda porzione di superficie.
