Lecture
This lecture covers the different types of foundry defects such as unwelcome and cold drops, sink marks, cracks, pitting, blistering, and macro-segregation. It explains the causes of these defects and possible solutions to prevent them, including controlling filling pressure, adapting masselottage, and applying electromagnetic fields. The instructor also discusses the physico-chemical interactions between molds and parts, mold cracking, and mold erosion in sand foundries.
