Effect and optimal variable of mangosteen peel powder for green sand mold

Abstract

Metal casting with Green sand mold is essential for participation in the manufacturing industry that requires natural resources and chemicals as an element. This research studied the effects of the right mix of mangosteen shell powder on green sand mold. The objective is to study and analyze the mixture of moist sand formations consisting of natural sand, bentonite, mangosteen shell powder and water affecting the properties of green sand mold by experiment method. Starting from studying relevant information of natural materials that affect sand mold and planning experimental design by using the experimental design program for the trial version in the experimental design and analyze results. The results showed that mangosteen peel powder had an effect on the properties Compression strength and higher hardness of sand mold but does not increase the ability to release a lot of air permeability The optimum blend ratio was composed of 90% reused sand, 7% bentonite, 1% water and 2% mangosteen powder by weight air permeability. The hardness of the sand casting was 0.71 kg/cm2, 47.36 and 94.06 Scale B respectively.
