All companies in the automotive industry need to combine quality and competitiveness to survive in order to reach customer's expectation to not lose profitability. In this sense, a design review is essential to maintain the company's competitiveness, if it represents an opportunity to improve quality and costs. Thus, a manufacturer of window regulator system identified an opportunity in the metallic insert of brass (CuZn39Pb3), which has quality problems from your supplier. A new supplier proposed the manufacture of the product in aluminum (6082-T6), providing better quality at a lower cost. Based on this information, the objective of this work is to verify the feasibility of the proposed insert in comparison with the previous insert. For this, a literature review was demanded on issues related to product components, the materials used and their manufacturing processes, technical specifications required, mechanical properties involved and the method for the materials analysis. To verify the feasibility of this change, it was necessary that the product go through some tests, to ensure its functionality. The tests were performed in accordance with the technical requirements of the company and its customers and consisted of tests to check the push out force, torque and contact corrosion in inserts. With the results, it was used the method of Material Performance Efficiency (MPE) to compare the performance of brass and aluminum inserts. Finally, the project presents the test results and a comparison of them, concluding that the aluminum insert is the best product, considering performance and cost in the analysis. |
