2.2. Materials and methods The extruder machine was manufactured using parts that are not available in Morocco. The manufacturing of the component’s part was started by the conception using Computing aided Design and the realization using mechanical turning machine, mechanical milling machine, and laser machine, was used to perforate the shaping die with high precision of 1,75 and2,5mm. the raw material used in this study is Polycaprolactam polymer PA6 (2,5 kg,, NOVAERUM Morocco) it’s shown in Fig. 2.
