| Outline of Final Research Achievements |
In order to clarify the relationship between residue formation and dynamic equilibrium in thermal decomposition gas layer on evaporative pattern casting process, influence of molten metal temperature on mold filling rate and thermal decomposition products formed during casting were examined. The dynamic equilibrium is depolymerization type until 900℃ of molten metal temperature, and does not become static state due to decomposition of monomer over 950℃ of molten metal temperature. Also, the amount of liquefied resin was extremely large. Carbon particles as results of thermal decomposition were suspended in the liquefied resin. In addition, molten metal flow become slow, and residue was formed.
