          Tapered Pellet Dies: Countersink

           
           

          Countersunk inlet: Countersunk pellet dies have the inlets where the material enters the pellet die countersunk into the surface of the die. This acts to encourage material into the holes of the pellet die. There are a wide range of different shapes possible for the countersink, but these are normally 55 to 60 degrees. This shape and degree of countersink is very important as a countersink that is too deep could give the die a pre-compression effect. Possibly risking clogging and blockage, this is especially the case in the pellet dies first hours.
