摘要： A riser sleeve apparatus (10) for preparing and insulating a passage (14) within which molten metal is accumulated prior to its movement into a mold cavity which includes an inner surface (12) which longitudinally extends between a first end (16) and a second end (18) wherein the inner surface bounds the passage. The riser sleeve further includes an annular lip (20) which is positioned adjacent the second end and extends inward into the passage. When the riser sleeve is positioned about a plug of a pattern, the annular lip deforms to seal the passage at the second end. A process for forming a cast metal article using said riser sleeve apparatus. A process for forming the riser sleeve apparatus.

摘要： A process of positioning a riser sleeve about a plug of a mold cavity pattern. The riser sleeve is positioned to engage the plug to prevent sand from entering the interstitial space between the riser sleeve and the plug. The riser sleeve may comprise a deformable annular lip for engagement with the perimeter of the plug. The riser sleeve may engage the plug in sealing relationship.
