Screw Installation 1

Screw Installation 1
Vol.20 #3, Dec. 1993

During installation or removal of an extruder screw, it is very easy to damage the sharp bimetallic barrel liner edge at the breaker plate recess.

To prevent this, always insert a steel ring into the recess made with an outer diameter the same as the breaker plate and a bore to match the barrel ID with a slight chamfer. The ring will protect this delicate sealing edge.
