Abstract
This paper explores the evolving significance of metal injection molding (MIM) technology, particularly as a promising alternative for the precise and cost-effective manufacturing of small-scale, high-volume products in the automotive industry. Despite its growing adoption, the quality control processes for intermediate “green” parts and the final metal products are not yet well established, posing significant challenges in ensuring product reliability and consistency. Furthermore, the research thoroughly examines the recycling of MIM feedstock and its impact, especially on the change in carbon content. Scanning Electron Microscopy (SEM) images were taken of the samples, the chemical composition was analyzed using Energy-Dispersive X-ray Spectroscopy (EDX), and the pearlitic regions of samples from different generations were compared using image analysis software on microscopic cross-sections.
