Abstract

Pattern is a description of the shape of the product to be made. Patterns can be made of wood, plastic, sterofoam or metal. The choice of pattern material depends on the shape and size of the cast product, dimensional accuracy, the number of cast products and the type of casting process used. This study uses the pattern of mahogany wood as a pattern making material and gray cast iron that are remelting in induction kitchen for casting with sand mold CO₂. Data analysis shows that the process of designing using software solidworks 2017 is very profitable and simplify in the work of 2D and 3D images. In making Centrifugal Rotary Pump Cap pattern with mahogany wood facilitate researchers in making patterns and economical prices and patterns made of wood can be used repeatedly By foundry using the sand mold method CO₂ makes it easier to manufacture the product, because the mold has hardened and the mold will not be easily damaged when the pattern release from the CO₂ sand mold. The gray cast iron characteristic from the test of the chemical composition of the gray cast iron material is found some elements, among others (Fe) 94,69%, (C) 2,7693%, (Si) 6,7665%, (Mn) 0,3904. %. The percentage of shrinkage from the castings is 1,62% of the original pattern by the method of casting the CO₂ sand mold
