Influence of the ash content of the material of the model on the quality of the castings obtained when casting by burning-out models

Burnt-out casting is one of the varieties of precision casting. The technology is used in the manufacture of critical parts used in all areas of mechanical engineering. The technological process of investment casting is similar to another precision casting technology - investment casting, but it has a number of advantages, namely: the efficiency of obtaining a product, the overall savings in project implementation time, and in some cases, reducing the cost of materials. The introduction of additive technologies in the foundry allows for an intensive production process.
