EXPERIMENTAL VALIDATION OF THE EFFECT OF PISTON SPEED ON THE HOMOGENEITY OF DIE CASTINGS

One of the most progressive technologies in foundry is die casting, where a significant part is formed by die casting of castings of a lower weight category. In the case of castings cast by pressure casting technology, one of the important quality indicators is the internal quality of the casting presented by internal defects. In addition to the alloy used, the shape of the mold and the filling chamber also affect casting defects. Casting parameters such as pressure and speed significantly affect the quality of the resulting casting. The resulting homogeneity of the castings is very important in terms of mechanical properties.
