    An extrusion die is a precise and specific tool made by cutting an opening through a blank of steel. The shape of the opening will match the finished rubber cross section desired for an extruded part. Once in place, the rubber material will be forced through this die via the pressure that builds up from the revolving screw of the extruder.
