Abstract

"MASSAS DE NúCLEO DE FUNDIçãO". A presente invenção refere-se a um processo para preparação de núcleos e formas para moldes de fundição, à base de materiais de forma e aglutinantes orgânicos ou inorgânicos e um aditivo. Por esse processo são empregados materiais formadores de poros, para tornar supérfluo o emprego de gomas de acabamento e para evitar a formação de nervuras de folhas.
