Piston Assembly For LMI-Series Melt Flow Indexers

[Model shown is PART NUMBER 7051-72. Contact a Dynisco representative to determine your piston model.

» Key component of any LMI unit, the piston extrudes a polymer by applying a steady, constant force into

the barrel of the LMI, forcing it through the capillary.

» Piston assemblies may vary depending on the generation of your Dynisco Melt Flow Indexer. If you do

not know the model number of your piston assembly, contact a Dynisco representative.

Pin Vise

PART NUMBER 0051-38

» Used to secure the carbide orifice in place while cleaning o polymer after a test.

Bronze Scoring Rod

PART NUMBER 0051-47

» Used after thorough swabbing of the LMI’s heating chamber. The bronze brush scores the surface

of the barrel to clean out tough polymer residue.

» Bronze Scoring Brush not included, see below.

Bronze Scoring Brush

PART NUMBER B0555

» Replaceable scoring brush that can be threaded into the scoring rod. The bronze brush scores the

surface of the LMI’s internal barrel to clean out tough polymer residue.

» Bronze Scoring Rod not included, see above.

Pallette Knife

PART NUMBER 0051-53

» Used in manual cutting of polymer samples during certain test methods.

» Optional on LMI5000 and LMI5500 series melt flow indexers equipped with

autocutter mechanisms

Go/No-Go Gauge for Carbide Orifice

PART NUMBER 0051-55

» Used to measure the capillary of a carbide orifice to ensure that its diameter

is within tolerance. If the capillary is within tolerance, it will fit into the “Go”

side of the gauge (0.0823in.) and will not fit into the “No-Go” side of the gauge

(0.0827in.).

Beaker, 10mL

PART NUMBER GP0300

» Used to weigh and hold polymer pellets for use in a melt flow indexer

» Does not include shown tools. Purchase separately from models in catalog, or see our

comprehensive toolkit oering at [D5000-TOOL].

Carbide Orifice

PART NUMBER 0051-46

» Die with central capillary within ±0.0002in. of the listed diameter

» Inserted into the barrel of a LMI’s heating chamber, plastic melt flows through

Orifice Brush

PART NUMBER GP0310

» Used to clean the inside of the carbide orifice to remove residual plastic material

Funnel

PART NUMBER 0051-80

» Used in filling the barrel of a melt flow indexer with a polymer charge of

predetermined weight and volume.

Cotton Swabbing Patches, 1000pc.

PART NUMBER GP0103

» Used with the cleaning tool to remove the residual polymer from the LMI’s

heating chamber.

Laboratory Weighing Scale

PART NUMBER 1192001

» Used in certain types of testing with the LMI to determine the mass of polymer

samples.

» Accurate to the third decimal place, three-door glass shield chamber, comes

with a mini-USB cable and 2 USB connectors.
