Screw Performance
Vol. 17 #3, Dec. 1990

Evaluate your screw's performance every time you pull your screw by inspecting the appearance and cleanliness of the flights. Look for areas of excessive wear or discoloration indicating excessive frictional heating. Then modify the barrel profile to decrease pressure in the section by increasing temperatures.

If the performance is okay, run the new profile and reinspect the screw at the next pulling to see if you have changed the wear rate. Keep records.
