2.3.6. Shaping die: Shown in the end part of the filament extruder where the filament comes out. it has a cylinder shape with no top surface, and a little hole in the middle of its bottom surface, generally made of brass because of its capacity to withstand high temperature. in the experiment we will use two shaping dies, one has 1.75mm of the little whole diameter and the other has 2.5mm. it has an inner hex so that it can be attached to the end of the steel tube.

2.3.7. Heaters The heaters are fixed on the lateral surface of the copper tube so that the thermoplastic material existing inside can be fused at 350° degrees, in order to facilitate its extrusion in the final step of the process. 2.3.8. Guide bearing: The guide bearing is used between the extremely side screw and the tube to guide axially the screw shaft while reducing, at the same time, the friction during the screw’s rotation. 2.3.9. Thermal regulator: The thermal regulator has an important role in this system by controlling the Increase of the material’s temperature, to not exceed the limit fixed previously according to the thermoplastics materials used, for protecting its compositions. 2.3.10. Locking nut: Metallic stop nut with 25mm of diameter that goes right between the steer tube and the support plate, it has two sides to fix it? and it plays a very important role in the system which is to make sure that the hole in the steer tube where the raw materials get in stays always facing the top. 2.3.11. Motor: In order to assure the transfer of the material used in this process, a motor is coupled with the screw shaft which gives it the necessary power to move the material, furthermore, the motor’s type used is exactly the one selected for lifting the vehicle window.
