Title (EN) APERTURE FORMING MEMBER FOR GASIFIABLE PATTERNS
(FR) MEMBRE FORMANT OUVERTURE POUR MODELES GAZEIFIABLES
Abstract:
(EN) A gasifiable pattern assembly (10) as used to produce castings by the full mold or cavityless process, has an aperture forming member (16) positioned between separate elements (12, 14) of the assembly. The aperture forming member (16) provides constricted interconnection of a casting with its associated gates and risers so that the gates and risers may be easily separated from the casting.
