Melt Flow Testing

The test system consists of:

• A heated barrel with a removable die at one end
• Temperature control of the barrel
• A piston to fit in the barrel

• Masses to apply various weights
• An encoder to measure the deflection of the piston (required for melt volume rate measurement)
• A die plug to keep thinner materials in the barrel until test start
• A weight Lifter to apply weight sets automatically at test start
• Hastelloy (non corrosive) barrel for chemically aggressive materials
   

Control and data analysis software package to:

• Input test parameters for a test method
• Control the machine
• Calculate MFR and MVR values
• Analyse Data

Instron - MF30 

• MFR (g/10min) – Melt Flow Rate
• MVR – Melt Volume Rate
• Multi weight tests – 2-5 masses are applied at stages during one test.

• Raw Material Suppliers
  • QC testing of produced batches
  • R and D and new materials
• Polymer Moulders
  • Checking batches when they are delivered
