Optimizing Plastic Extrusion Process via Grey Wolf Optimizer Algorithm and Regression Analysis

Karaoglan, Aslan Deniz


One of the most widely used methods in the production of plastic products is the extrusion process. There are many factors that affect the product quality throughout the extrusion process. Examining the effects of these factors and determining the optimum process parameters which will provide the desired product characteristics; is important for reducing costs and increasing competitiveness. This study is performed in a manufacturer that produces plastic cups. The aim is to optimize extrusion process parameters of this company in order to achieve 1.15 mm thickness at the produced plastic sheets. For this purpose, the thicknesses of the sheet produced with different process parameters were observed throughout the production processes to be able to model the problem as an optimization problem by means of the regression modelling. Then, the developed model is optimized via the grey wolf optimizer (GWO) algorithm considering the desired 1.15 mm sheet thickness.
