Model structures of KS-5A and KS-7 are focused for production of the melted models on automatic machines of rotary type, semi-automatic lines, pneumatic, lever and hydraulic pressa. The model structure of KS-7, besides the specified conditions of production of the melted models can be, also, used for a press fitting of compression molds in a pastelike state on manual syringes as possesses a wide interval of temperatures of a pastelike state.

Model structures of KS-5A and KS-7 (analogs of R-3, MVS-3A) are characterized by steadily high technological and consumer properties. As well as at the prototypes (R-3 and MVS-3A) technological parameters of model structures of KS-5A and KS-7 (linear shrinkage, the prevention of education utyazhin in the melted models, the constructional durability of the melted models) are regulated by change of content of air in them at a press fitting in a compression mold. The recommended content of air in model structures - 15 … 30% on volume, pressure of a press fitting of model structure in a compression mold - 1,7 … 2,2 MPas, temperature of model structure at a press fitting in a compression mold - 57 … 61 0C. Besides, with increase in number of remeltings of model structures of KS-5A and KS-7 their technological effectiveness, as well as with increase in a share of return in fresh model structure increases.

Model structures of KS-5A and KS-7 are regenerated and suitable for use after repeated remeltings, do not support flying, unhealthy the person of substances.

2. Model structure for production of the melted models
castings of especially responsible appointment

For production of the melted models of castings of especially responsible appointment (for the aviation and ship-building industry, production of gas-turbine installations, etc.), the enterprise of ChNPP "Karion-Service" developed and makes the model structure of KS-102 meeting the modern requirements of production of molding.
