The final products that emerge from innovative production processes for different electric vehicle parts are Aluminum profiles of all designs for applications such as doors, structural and semi-structural parts, etc. The production line of these products is automated, where every work process, is controlled by CNC panels in which they are implemented and programmed with different software. The automation of the production processes tends to improve the quality of the product and tends to optimize the production process to minimize and decrease production waste. This paper presents the production process of different electric vehicle parts and how their quality is evaluated by using PFMEA analysis according to the quality standards. The implementation of quality standards resulted in product quality and enterprise quality management system improvement.

An option to modernize the worm of the strand extrusion machine is proposed. The technical solution of this worm of the string extrusion machine is the improvement of the mixing section of the extruder worm, which is located in the gap of the screw line in the homogenization zone of the extruder. This design of the mixing section of the worm of the strand extrusion machine allows to intensify the process of dispersion of agglomerates and mixing of the dispersed phase in the dispersed medium and as a result to obtain a homogeneous structure of the polymer, which in turn allows to improve the quality of the final product.
