Analysis of strength on thick plate part using Taguchi Method
Abstract
The tensile strength of the certain moulded parts is important, especially for the product which requires the strength for functionality and quality. It is known that parameter setting of injection moulding had interaction between the tensile strength of the product manufactured in plastic industry. Trial and error method that usually implemented in the industry is known will cause the company lost in material quantity in order to provide specific product performance requirement from customers. To out run these issues, the Taguchi parameter optimisation was introduced, which attempt to minimize the
production cost at the same time improving the tensile strength of the product. The
Taguchi method is known to provide a basis for determining the functional relationship
between controllable product and the results of a process. This study can classify into
three phases which are selection of part design used and simulated the flow of the
selected material into the mould cavities with Fill, Fill + Pack and Cool (FEM) analysis
with Autodesk Moldflow Insight software. Then recommended parameter setting from
the simulation works result were adapted into the injection moulding machine and the
product undergone tensile testing. Throughout the result of tensile testing using the
recommended parameter obtained from the simulation. The most significant parameter
that affected the tensile strength of the thick plate part were obtained by applying the
Taguchi method and from the analysis also will be acquire the new setting that is the
optimal parameter setting. The results of tensile strength of the optimal parameter
setting will be compared with results of recommended parameter setting by the
mathematical method.
