Research On The Thin-wall Aluminum Art Part Lost Foam Casting Technique

Lost foam casting(LFC)is a new foundry technology which has a good molding quality. This technology was invented for art casting. Because of its character in casting, it was attracted in the foundry. Nowadays, LFC has been applied to produce complex automobile part as block and cylinder head. There is not many application in the art casting. So studying on the LFC-art casting is propitious to extending the feasible field and using of the LFC in art casting.The key point of LFC is the choosing and molding of the foam material. This thesis is base on the experiments. In the experiment, the characters of EPS, EPP and EPE have been compared when they are use in LFC. And some research in the capability of the material used in LFC have been taken, especially in the art casting.By the study of the molding of the foam pattern and the compare with different cutting methods, the conclusion of the character of the different cutting has been made, especially in the LFC-art casting. Some needed to pay attention when the 3D designed is pointed out.The basso-relievo board of the LFC casting committee and the five-star member tablet have been designed independently based on UG/Modeling module .the foam pattern of the board has been produced with the EPS rapid prototyping. The tablet of LFC committee and its mould have been molded and tooled.Because of the characters of the LFC and art casting, some studies are taken on the LFC process of thin-wall casting. The condition of the thin-wall part's foam molding and its technology in molding summed up, which offers some important data and experience in the LFC-art casting.
