ABSTRACT:
The present invention relates to a method of removing a gate remnant from a casting comprising the steps of: providing a gating including a casting and a gate remnant, the gate remnant including a riser and at least two in-gates, wherein the at least two in-gates are attached to the riser and to the casting; weakening one of the at least two in-gates; and applying a first force to one of the at least two in-gates, wherein the first force severs the one of the at least two in-gates and thereby urges the riser away from the casting such that the other one of the at least two in-gates is severed, thereby separating the gate remnant from the casting.
