ZL-3014B Automatic Melt Flow Rate Meter.pdf
ZL-3014C Melt Flow Indexer meets the requirement of
GB/T3682-2000,ASTM D3364(sand ASTM D1238-98.And also ,we design and
manufacture the instrument after we made a reference of similar
standards ,such as JB/T5456 and ISO 1133 .It is used to determine
the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR)
of thermoplastics materials .
It adopts auto sampling method and the cut samples are weighed up
by balance when it is used to determine MFR .When it is used to
determine MVR ,it measures the time which the piston is used to
move the specified distance first through the displacement
transducer and auto timer system and calculates MVR according to
the formula later.
The final results of the two methods are all displayed on the
machine’s LCD screen and printed and exported by computer .The
instrument has high accuracy on data measurement with simple
operation and stable capability.
It is not only suitable for the tests of engineering plastics with
higher melt temperature ,such as PC ,FI plastics, nylon ,but also
for the plastics with lower melt temperature ,such as PE ,PP ,POM
,PS ,ABS resin and poly carbonic acid ester ,etc .
It has wide range of applications in some industries ,such as
plastic fabrication ,plastic goods ,petrochemical industry ;collage
and university and science and research institute and commodity
inspection department .

6. Standard test load (kg ,8 grades)
1st grade :0.325kg = (piston stem +weight tray +heat insulation sheath
+weight # 1) = 3.187N
2nd grade :1.200kg = (0.325+weight # 2 0.875) = 11.77N
3rd grade :2.160kg = (0.325+weight # 3 1.835) = 21.18N
4th grade :3.800kg = ((0.325+weight #4 3.475) =37.26N
5th grade :5.000kg = (0.325+weight #5 4.675) = 49.03N
6th grade :10.000kg = (0.325+weight #5 4.675+weight #6 5.000) =98.07N
7th grade :12.500kg = (0.325+ weight #5 4.675+weight #6 5.000+ weight
#7 2.500) =122.58N
8th grade :21.600kg = (0.325+ weight #2 0.875+ weight #3 1.835+ weight
#4 3.475+ weight #5 4.675+weight #6 5.000+ weight #7 2.500+weight
#8 2.915) =211.82N
The test load relative error shall not be more than ±0.5% .
