AB  - In this paper, results of investigation of casting technology of complex thin-wall copper alloy castings with accent on Lost Foam casting procedure are given. Phases of casting procedure were investigated, along with important process parameters and their influence on structure and properties of obtained castings. This technology enabled obtaining of the castings with complex construction and thin walls, and significant savings in casting procedure: expensive operations such are cleaning and machine processing of castings are minimized, while exploitation of metal is increased. Critical parameters of the process were investigated: casting temperature, types of refractory coatings, types of polymer models and their influence on formation of the structure. Results showed that new technology can be applied for obtaining of quality copper alloy castings which can be widely used in mechanical industry.

AB  - In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that patterns and gating of moulds, made of polymers, stay in the cast till the liquid metal inflow. In contact with liquid metal, intensely, in relatively short time, polymer pattern is been decomposing and evaporating , accompanied by castings crystallization. In order to achieve qualitative and profitable castings production by the EPC process it is necessary to reach the balance in the system: evaporable polymer pattern-liquid metal-refractory coat-sandy cast in the phase of metal inflow, decomposition and evaporation of polymer pattern, formation and soldification of castings. Results of this investigation of this process relate on application of puffed polystyrene of various densities (kg/m3): 18, 20, 25. Application of lower density polymer (20 kg/m3) gave positive results on structure and properties of silumina castings obtained using this casting method.
