9 Section 9 – Manual & Automatic Extrudate Cut-Off Tools
Tinius Olsen now offers manual and automatic extrudate
cutters options to further automate the testing process. Both
the manually operated (hand cranked) and the automatic
(motorized) Cut-Off tool options are designed to use a
precision motion to make a clean cut of the extrudate as it
flows from the orifice of the die during a melt flow
determination. The automatic cutter may be operated from
the LCD touch screen, either manually or its operation can be
preprogrammed into a testing routine. However, the cutters
may not be suitable for use with all materials. Materials that
are sticky in nature may not be suitable for use with these
options.
To work properly, the cutters must be centered on the initial
set up. The idea is to center the tool trajectory at its peak at
the orifice center as shown above. To do this, follow the
steps below. The initial set up should be done with no plastic
n the furnace, but to check performance, a live charge should
be used.
9.1 Tools Required:
1. Allen wrench set (imperial, i.e not metric)
