| Abstract [eng] |
In this research project, for manufacturing the masterpiece or master model, the first 3D-CAD model was created by the solid work software, this 3D-CAD model was created with all parametric requirement which is possible to get all geometric parameter in the mould cavity. After that, the masterpiece generated in the 3-D printer. With the help master model, the moulds were created by various silicon rubber. For this experiment, we used various silicon which is Bluesil RTV 3428 A & B silicone rubber, CENUSIL RTV-2 M 380 silicone rubber, Silicone ADDV-10, Silicone Rubber KDSV THX-30. After producing the mould with silicones, we analysed the finishing of cavity surface. In this project, the casting process was done by using the epoxy resin. By using the epoxy resin, we generate four casting product with improvement with every casting product, and after that, we analysed the accuracy and finishing in every casting. And the last stage of the paper is to cost calculation of product cost, in which we calculate the cost of one product with all different silicon mould, cost calculation is done for one product, ten product and hundreds product of every silicone mould. The result of the experiment would be beneficial for the rapid prototyping and the small moulding part producing companies. |
