Cleaning The Die Bore - Ametek Davenport PET Plus User Manual

Insert the charging tool into the top of the barrel until it touches the top of the follower.
Push the charging tool completely down through the barrel to remove the remaining polymer and the
follower.
Hold the follower with tweezers then remove any polymer from the sides and faces using a sharp
blade.
Fold a cleaning patch in two then place over the tip of the barrel cleaning tool. Push the cloth into the
top of the barrel using the tool and push the tool down completely through the barrel.
Carefully remove the cloth from the barrel cleaning tool and withdraw the tool upwards. Visually
inspect the barrel and, if necessary, use another cleaning cloth until the barrel is completely free from
polymer and the inner bore is shiny.
A final cloth coated with a small amount of silicone oil may be used to coat the barrel and make future
cleaning easier.
WARNING: The cloth and barrel cleaning tool may become hot during the cleaning
process. Wear heat protecting gloves when handling these items.
Polymer fumes may be emitted from the top of the barrel during the visual examination
process. Wear protective glasses or goggles when viewing the interior of the barrel.
If traces of polymer are still present in the barrel bore, these can be removed using the wire brush.
Note that this procedure should not be required if the barrel is cleaned immediately after each test.
Put the cleaning tool through the loop in the wire brush handle then move the brush up and down the
length of the barrel to remove the traces of polymer.
Use another cleaning cloth until the barrel is completely free from polymer and the inner bore is shiny.
Do NOT use the brush until after the barrel has been cleaned using one or more cleaning clothes
otherwise the brush will become clogged with polymer.
