Abstract:
Furan-No-Bake (FNB) sand mold system is a technology in high demand due to its good surface fi nish, dimensional stability and shakeout characteristics. It is avery tedious process to characterize the quality of FNB cast product due to the complex existence of parameters that aff ect the quality of the motor body castedproduct. In this paper, a mathematical model has been developed based on the experimental data, and sensitivity analysis was performed to identify and comparethe infl uence of the casting parameters such as resin percentage, catalyst percentage and temperature of sand on the compressive strength of the mold and toknow the parameters that must be carefully controlled.
