Abstract

The purpose of this project is to analyze the behaviour of the effect of process conditions in vacuum casting process. This research project was done by create the design product based on the step design and chose the best design product to fabricate by using the Fused Deposition Machine. Before that, the design product 3D modeling of prototype product was prepared by using Solidwork software and will transfer in the fused deposition machine. With the prototype product, the mould will be produces by silicon rubber mould for vacuum casting process. To produce the silicon mould, the size of mould and type material are used must be determine with the calculation of volume material to use. Assemble the wood frame and enter the model participate by setting the position sprue and gate. After silicon mould finish, mould should cut along the parting line and remove the model product, suspension rod completely and cleaning the mold. Place the mould in the oven to complete the solidification. The resin polypropylenes are selected as material of fmal product. During the process, the parameter can be adjusted by referring the data sheet MCP machine. The parameters setting will affect the final product. After that, several products will produce with different parameter and compare the structure product. The effect can be detected for each product when experiment conducted. With using the surface roughness tester, the surface product can analyze the level of roughness and other effect can analyze by comparison. By this project the result of product will be found out and optimum parameter can be obtained. In this project also to calculate the volume material resin for prevent the wastage during process. With the spreadsheet the volume material can calculate the how many materials used to produce the product.
