Molding a part e.g. a cylinder head of a vehicle by lost model, comprises fixing a model of a part on a descendant defining an axis of metal casting, coating the model by a refractory layer, and casting a metal sublimating the models

摘要

The method comprises fixing a model (10) of a part on a descendant defining an axis of metal casting, coating the model by a refractory layer, and casting a metal sublimating the models. The model of the part is fixed in points of fixation, which is inclined on a line with respect to the axis of metal casting. The descendant extends along the axis of the casting through supply channels, which are transverse to the axis of metal casting. The supply channels have different length. The line is inclined at an angle of 3[deg] with respect to the axis of casting. The model is made of polystyrene.
