Experimental and Theoretic Research Regarding Extrusion Optimization for Reinforced Polyamide (PA 6.6 – 10 % GF)

Abstract:

This paper presents the possibility of extrusion optimization using Design Expert software for statistical analyze and also for the recommendation of some manufacturing data. Mechanical characteristics are determined on samples from extruded tubes. On these samples, ANOVA (Analysis of variance) software is used, in order to determine the optimal values of the temperatures in different zones. The material is polyamide 6.6, reinforced with 10 % glass fiber (PA 6.6 – 10 % GF). The authors want to present the influence of the reinforcement degree upon some mechanical characteristics of the products made by extrusion. Considering the homogeneity of the polymeric melt the product’s quality will be analyzed. During the extrusion process a series of parameters (extrusion speed, the pellets feed, processing temperature etc.) are involved and they must be taken into account to achieve calibrated and qualitative products.
