Casting process using a disposable plaster mold. Beskrivning The process Two separate mold halves are made by covering two pre-lubricated master molds with liquid plaster. The molds are vibrated to remove air bubbles and to ensure that all voids are filled. Lubrication makes the removal of the mold halves easier after solidification, the mold is then processed to add the inlet and other details necessary for an adequate molding. The dies are then assembled to complete the form and cores are added if required. Then the mold is filled with molten metal, which on solidification is freed from the cast that cannot be reused. In cases where the part has a flat side one mold may be sufficient which greatly simplifies the process. Gypsum forming Process photos Process films
