Abstract

Wax injection machining is the only technique to produce many ideal products in large volumes, which is the most common method in the investment casting process. One of the products that has the highest number of orders in metal casting companies that use investment casting techniques is the VS 2/4/6 X pump casing product. The VS 2/4/6 X pump casing product consists of 4 components, each of which is injected into a different mold and eventually assembled into a product. The problem that is often encountered in wax pattern injection results is product defects, where in the wax pattern manufacturing process there are standards for the size and type of product defects, among others, if the size of the sink mark defect is 0.5 mm, for the size of the flow mark with a length of 1 mm and a depth of 0.5 mm and for flash with a wide defect area criterion and a magnitude of 30% of the pattern surface area. The parameters to be analyzed to reduce product defects are injection time, injection pressure, and holding time. This research uses response surface method with 15 run orders with 3 replications and uses Box-Behnken Design for research experiment design and ANOVA to analyze the data. Based on the analysis results. It was found that the optimal parameter combination is the value of injection time 80 s, injection pressure 35 bar, and holding time 50 s. From this configuration, the minimum product defect is 1.5972 pieces per products.
