Multi-Response Optimization of Injection Moulding Processing Parameters Using the Taguchi Method

Determining the superlative optimal processing parameters on multi-responses is an intricate task. A new constitutive approach in solving multi-response problems using a combination of single responses through the Taguchi method is developed in this study. Mechanical properties improvement of the part made of recycled PP is highlighted to demonstrate the significance of the approach. From the results, the flexural modulus and strength of the part produced by the approach improved to 4.1% and 6.7%. Therefore, the solution from this approach can be used by engineers who are searching for a simple and straightforward optimal solution using the injection moulding process.
