Abstract
A wear ring for a piston of a die-casting apparatus comprises an annular body having a gap extending therethrough. The gap is configured to define at least two circumferentially offset pairs of circumferentially spaced apart facing surfaces. The facing surfaces of each pair are angled and configured to contact each other in a flush manner when the wear ring is circumferentially compressed.
