Abstract

Describe herein a method of manufacturing a metalic to a near net-shape which is resin bonded sand casting process that use phenolic as a resin binder. This study was to determine the factors that significantly affect the sand mould properties which was resin and hardener and evaluate the feasible range of factors for producing a phenolic sand mould. The three-level full factorial design with 9 experiments run was performed for responses that were compressive strength, tensile strength, transverse strength and loss on ignition (LOI). DOE full factorial design was used to study the effect of two factors on the phenolic resin bonded sand mould and their possible interactions. The collected data was then converted into graphical form that were bar chart, main effects plot and interaction plots and these plots were analyzed. From the result obtained based on the four of responses, the sample from ratio 9 was the optimum. This was because this ratio achieved the standard value for every responses studied. The most suitable ratio parameter was from ratio 9 that contain 3% of resin and 20% of hardener
