:: THE TERMINOLOGY OF DIES
 Effective thickness
 Compression index
 Outside relief
 Variable relief
 Reverse taper relief
 Countersink
 Taper inlet
 Well inlet

 

 

For a few 'spongy' materials, a reverse taper relief can be used, gradually tapering out as the pellets leave the compression area. This type of hole is used for 'spongy' materials such as alfalfa or fish feeds. The effect of this specification is that when the wear enlarges the diameter of the hole, decreasing the compression index, this is partly recovered by the length of the compression thickness increasing as the diameter increases.
