Unpacking the Indexer
The DYNISCO POLYMER TEST'S Melt Flow Indexer comes in a heavy duty,
double-walled cardboard container. First, open the main box and remove the
instrument. Several boxes will also arrive by UPS; check that all boxes are
received. They are coded 1 of 5 or 3 of 5, indicating the total number is five. It
is recommended that the shipping carton be saved a few days until you are
certain the machine works as expected.
Bench Requirements and Placement
Level the Melt Indexer
Typical laboratory benches are too high for efficient use of the indexers.
Cleaning can be difficult and requires awkward hand positions and forces that
could lead to carpal tunnel syndrome or back discomfort. We strongly suggest a
bench height of 29 inches (desk top height) for an average height operator.
Place the front of the indexer flush with the edge of the table. This will prevent
the operator from having to bend forward excessively when cleaning the barrel
and allow easier access to the back of the machine. As a minimum, the lab
bench should easily be able to support the indexer and operator (total approx.
300 lbs.). DYNISCO POLYMER TEST recommends placing from left to
right, if purchased, the melt indexer; printer; computer. Test shake the melt
indexer for stability. The bench top should also be able to withstand hot dies
and tools being dropped on them. Carpet protection is necessary near the
indexer since a hot die dropped on the carpet will quickly burn spots in it.
Adequate ventilation will also be required to remove potentially harmful fumes
from samples being tested. Consult the Material Safety Data Sheets (MSDS) on
the products to be tested and your material supplier to assess the magnitude of
your ventilation needs. You may wish to consider these ventilation needs when
positioning the instrument in the laboratory.
Most of the machine comes pre-assembled to your door, however, certain parts
are prone to breakage if they were placed in their normal operating position
during shipping. These items will need to be installed before safe operation of
the machine is possible. Other issues important to getting accurate data must
also be addressed before valid testing can begin.
Using the small round bubble level, supplied, level the melt indexer. Place the
level on top of the
COLD
barrel and using the adjustable screw feet, bring the
machine into level. Tighten the locking nuts to keep the feet in level position
Test shake the melt indexer for stability. Some companies bolt the machines
