A set of experiments on determination of the parameters 
of the gas release from a mold have been performed. The thickness 
of the casting, the thickness of the mold wall, the process time, 
and the temperature of the charged metal (liquid gray cast iron) were 
varied. The investigated molding sands were prepared from quartz sand 
and organic binders: M19-62 (urea resin), FF-1S (furanic resin), and 
PK-104 (phenolic resin). On the basis of the experimental data obtained 
the kinetic parameters of the thermal decomposition of the considered 
resins have been determined.

Keywords: mold, synthetic resins, thermal decomposition, kinetics.
