Characterization of shrinkage in plastic automotive parts obtained by an injection molding process with different types of thermoplastic polymer

This project addresses the challenge of dimensional shrinkage in automotive parts manufactured via injection molding, a critical defect that affects component quality and functionality. Despite the importance of injection molding in the industry, many current studies rely excessively on numerical simulations that do not always reflect the actual material behavior. The research proposes an advanced experimental methodology using X-ray scattering techniques (SAXS and WAXS) to evaluate molecular orientation and crystallinity, alongside the hole-drilling method to measure residual stresses non-destructively. These data will allow for the correlation of injection parameters with the final properties of the parts. Expected results include the creation of a predictive database and the validation of mathematical models, enabling the automotive industry to optimize processes, reduce material waste, and improve energy efficiency. This approach not only enhances industrial competitiveness but also aligns with circular economy principles by minimizing manufacturing defects.<br/><br/><b>Goal</b>: <br/>Analyze the influence of injection molding parameters on dimensional shrinkage, molecular orientation, and residual stresses in thermoplastic automotive parts. The goal is to establish quantifiable relationships to optimize the design and manufacturing of plastic components.<br/><br/><b>Research lines</b>: <br/>Design, manufacturing and re-engineering of automotive parts and pieces
