Abstract:
1. A method of removing a gate remnant from a casting comprising the steps of: (a) providing a gating system 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; (b) weakening one of the at least two in-gates; and (c) applying a first direct force to the one of the at least two in-gates which has not been weakened in step (b), wherein the first direct force severs the one of the at least two in-gates which has not been weakened in step (b) and thereby urges the riser away from the casting and at the same time causes the one of the at least two in-gates which has been weakened in step (b) to be severed without applying any additional force directly to the one of the at least two in-gates which has been weakened in step (b), thereby separating the gate remnant from the casting.
