David Blondheim Jr. & Alex Monroe Abstract Porosity formation in high pressure die casting (HPDC) impacts mechanical properties and casting quality. Much is published regarding micro porosity and its impact on mechanical properties, but there is limited research on the actual formation of macro porosity. In production applications, macro porosity plays a critically important role in casting
도전적인 알루미늄 HPDC 자동차 부품을 위한 로컬 스퀴즈 기술 Elisa Fracchia, Federico Simone Gobber, Claudio Mus, Raul Pirovano & Mario Rosso First Online: 05 February 2022 Part of the The Minerals, Metals & Materials Series book series (MMMS) Abstract A key issue in producing high-quality aluminium automotive components by the High-Pressure Die Casting process (HPDC) is minimizing the defects. For the HPDC technology,
