Abstract

Molding process needs material composition of sands print and other fastener materials which will affect smoothness surface of molding result object. Fastener material is very important for molding which use sands to bind the sands grains, so that sands do not corrode easily at pouring time. Besides have smooth grains, silica sands cannot stick by itself. Therefore, there is need additional fastener material blends, such as bentonite, molasses sugar, graphite, and water that could become a mold. This research uses experimental method. The independent variables are the composition procentage of silica sands and bentonite, and additional materials or constant (graphite, molasses sugar, and water), whereas the dependent variable is the defective mold. This research varies five kinds of print compositions and those five print compositions repeated three times. The variated compositions are A: composition of 60 % silica sands, 32% bentonite, 4% water, 3% graphite, and 1% molasses sugar; B: composition of 65% silica sands, 27% bentonite, 4% water, 3% graphite, and 1% molasses sugar; C: composition of 70% silica sands, 22% bentonite, 4% water, 3% graphite, and 1% molasses sugar; D: composition of 75% silica sands, 17% bentonite, 4% water, 3% graphite, and 1% molasses sugar; E: composition of 80% silica sands, 11% bentonite, 4% water, 3% graphite, and 1% molasses sugar. The research result show the good composition of print material is the composition of 60 % silica sands, 32% bentonite, 4% water, 3% graphite, and 1% molasses sugar.
