Applied processes and techniques in foundries. Production of castings using lost sand mold, mechanized mold making and core making- sqeezing, jolting, impact molding,blasting, shooting 3. Molding materials, sand, binders, mold and core making technologies, molding mixtures making and testing, sand reclamation techniques 4. Production of castings using permanent metal molds – gravity die casting, high pressure die casting, low pressure die casting, centrifugal casting 5. Melt flow in molds,properties of molten metals, castability , influencies on the fluidity of metals and alloys. Running systém design 6. Static and dynamic action of melted metals on the mold, upward metalostatic pressure calculation. Gases in melted metals, their dissolubility, methods of the melt degasing. Gases in the mold, methods of the mold degasing. Blow hole formation. 7. Thermodynamic of the crystalisation, homogeneus and heterogeneus nucleation. Primary crystalisation of the casting. Casting solidification – calculation of total solidification time, solidification velocity.Tthermal diffusivity of the mold. 8.
