Abstract :
The modified vertical sand casting mixer machine with a capacity of 15 kilograms is aimed at improving the quality of print sand melting in the metal casting process. In the molding process, the quality and homogeneity of the printed sand mix is essential for producing a good mold. The mixer that exists in the Materials Testing Laboratory of Bengkalis State Polytechnic cannot be used because there is only a frame, a container, and a simple mixer eye left. The research aims to modify the engine by designing a new mixer eye, selecting components such as: 0.5 HP propulsion engine, 1:20 gearbox, 1" diameter beam, 3" and 6", A42 belt, and determining the optimal combustion time. The process of modification included the design and manufacture of a new mixer eye, the test process was carried out by compressing the printed sand on the cylinder tube using a 35 bar hydraulic crack. After testing with the test method, a sensitivity of 4.4 kgf at 1.5 minutes, 7.8 kgf for 3 minutes, 9.1 kgf in 4.5 minutes, and 10.5 kgf during 6 minutes was obtained. So with the specified components, this machine can stir with a capacity of 15 kilogram.
