ABSTRACT:
A no-fume riser neck for use in molding the connecting neck between the riser cavity and general mold cavity in the production of metal castings. The neck is generally cup-shaped and preformed of sheet metal with a closed and substantially sealed upper end and an open flared and grooved lower end which is positioned open-end down on the face of a foundry pattern so that the sealed upper end is gas tight and separates the open riser cavity from the mold cavity and prevents extraneous material from entering and contaminating the mold cavity, and also prevents the unrestricted escape of objectionable gases and fumes from the mold cavity to the environment during the pouring cycle.
