Laser Measuring and
Extrusion Barrel Alignment
Laser Alignment Saves Time and Money
In almost all manufacturing plants there is a lot of Ɵme
and money to be saved by having your equipment
properly aligned. An investment in laser alignment helps
you by lowering replacement parts costs, decreased
downƟme, less wear and tear on criƟcal components as
well as lower power consumpƟon.
Extrusion barrel alignment is one of the most common
uses of laser alignment due to the small tolerances that
exist between a screw and extruder barrel. Proper align-
ment barrel relaƟve to the output shaŌ of the gearbox
will dramaƟcally increase the life and output of an extru-
sion line over its life cycle. The larger and longer the ex-
trusion screw is, the more important proper alignment
becomes. For example, a misalignment of .060” on a 4”
24:1 screw requires over 9000lbs force on the screw to
bend it to conform to the misaligned barrel. That
9500lbs of force translates to extra wear on the screw
and barrel which will lead to premature failure. Once the
tolerance between the screw and barrel is compromised
extruder output is reduced and line efficiency and profits
