【 摘 要 】

The article deals with the quality of castings of zinc and aluminum alloys made by means of casting under pressure. The study identifies causes of defects in the outer surface and their influence on the roughness of the castings. The connection between the working surface of the mold and the roughness of the obtained castings is determined. The relationship between operation life of molds and the roughness of the castings is shown. The solution which increases the operational stability of molds as well as the quality of the surface of castings is proposed.
