ABSTRACT:
A gravity poured foundry mold having a gating system and at least one complete mold casting cavity, the gating system allowing castings to be made in more compact molds, using less metal at lower temperature, obtaining less solidification strained castings, and requiring less fettling work and less pattern work. The gating system combines the use of a strainer such as a skin-strainer with any of several fluid restraining devices including but not limited to skin-strainer covers, restraining floating pieces, non-floating restraining pieces and blind floating pieces. Also disclosed are applications in which a skin-strainer is omitted. There is disclosed apparatus which may be standardized, thereby greatly increasing the ease, accuracy and confidence with which the gating system may be used in foundries which would have available to them sets of different sizes of standardized, interchangeable and prefabricated elements as disclosed herein. Also disclosed is a combination of this gating system with in-mold metallurgical treatment. The gating system may include a straining device at the casting skin level and or one or more straining devices at upstream levels in a sprue-feeder.
