ANALYSIS OF USE OF TAGUCHI METHOD WITH ITS TOOLS IN DIE CASTING FOUNDRY FOR OPTIMSATION OF VARIOUS PARAMETERS

Abstract

Die casting is a typicalmanufacturing process that can produce geometrically composite parts withthe
practiceand use of reusable mould or dies. Accuracy and quality of products are the first need of customers that must be
achieved by presenting high quality productsin die casting to the customers.
Die casting process have many problems and difficulties due to various defects problems, Some defects are blowholes,
improper filling, scratch marks, weld lines, cracks, cold shut, gas porosity, blisters, ejector pin marks, hot tears etc.
Main reasons of these defects are formed due to improper and unsuitable design of dies, or due to incorrect parameters
such as, Melt temperature, Holding time, and Injection pressure, Rate of cooling, Velocity of flow of molten metal, cycle
time, cooling circuits and other such parameter of die casting process. Sometimes these defects rise after manufacturing
of die and component production, which will be loss to the organization as there will be wastage of money, time and
material and also problem of customer dissatisfaction due to quality problems.
This review paper discuss use of taguchi method, DOE and Analysis of Variance (ANOVA) for optimization of various
parameters to reduce defects and improve quality by various researches in there research paper.
