Abstract

This work presents the technology of making foam plastics patterns used in casting as well as the final shaping stand. The analysis of the sintering process was carried out aiming at determining the influence of the pressure and the time of sintering on the flexural strength properties. The analysis of the research results confirmed that when the sintering pressure grows to the value of Pa =1,7 bar the flexural strength also increases, when the pressure value is higher than that, the degradation of the material takes place and the strength properties decrease.

Abstract

The work is a part of research into the reduction of energy consumption in the production of EPSthrough the modernization

of technological equipment used. This paper presents the results of research and analysis of heat transfer process between the water vapor

that was provided to machine, the mold, the product and the environment. The paper shows the calculation of the heat balance of the

production cycle for two types of mold: standard and modernized. The performance tests used an infrared imaging camera.

The results were used to develop a computer image analysis and statistical analysis. This paper presents the main stages of the production

process and the construction of technological equipment used, changing the mold surface temperature field during the production cycle

and the structure of the heat balance for the mold and its instrumentation. It has been shown that the modernization of construction

of technological equipment has reduced the temperature field and as a consequence of decreased of demand for process steam production

cycle.
