New Extrusion Setup

New extrusion setup
Vol. 23 #3, Dec. 1996

When starting up a "new" extrusion setup, start the screw rotation at about 5 rpm. Gradually look into the air gap (between the feed throat and throat housing) and make sure the screw is turning: Screws have been installed many times without having the key in place, or the key has fallen out during installation.

Also, make sure that anti seize is applied to the drive hub, to help installation and removal, and also if the key is left out and the drive quill is turning and the screw isn't, the screw won't gall to the drive quill.
