A mold pin is formed of a longitudinally extending rod-like body with a coll ar extending laterally or transversely from the body. The collar is of peripheral and longitudinal dimensions similar to those of a protrusion extending from the surface of a mold tray (mold casting or half), such that when the mold pin seats in the protrusion, the protrusion and the collar define a boss in the mold tray.
