What is it about?
investigates the optimization of the vacuum casting process by using Taguchi method. The vacuum casting process is one of the methods in Rapid Tooling Technology. The parts produced by vacuum casting process has its accuracy varies with the changes in the process parameters of the machine such as resin temperature, vacuum pressure time, mould temperature and some others. In order to optimize 3 parameters which are resin temperature, mould temperature and vacuum pressure time, the L’9 orthogonal array was used. From the results, it shows that the optimum parameters that may improve the shrinkage effect are resin temperature (30 C), mould temperature (60 C) and vacuum pressure time (5 min.). The shrinkage values between default and optimum parameter are 0.159 mm and 0.336 mm respectively. Thus, the improvement on the shrinkage effect was 52.4 percent. The study demonstrates that the better dimensional accuracy of vacuum casting process can be optimized using Taguchi Method.
