Plastic Melt Flow Index Meter

Model: MFI402, Plastometer ISO 1133, MFI test MFR, MVR

MFI402 Plastic Melt Flow Index Meter is for melt mass-flow rate (MFR), determined by extruding molten material from the cylinder of a plastometer through a die of specified length and diameter under preset conditions of temperature and load. Used to measure the melt mass flow rate of thermoplastic plastics under specific temperatures and pressures, reflecting the flow performance of materials through standardized testing. 


Feature of MFI402:

LCD display, Economical price, MFR method, motorized cutting, with micro-printer.

General introduction

MFI402 Plastic Melt Flow Index Meter is for melt mass-flow rate (MFR), determined by extruding molten material from the cylinder of a plastometer through a die of specified length and diameter under preset conditions of temperature and load. Used to measure the melt mass flow rate of thermoplastic plastics under specific temperatures and pressures, reflecting the flow performance of materials through standardized testing. 


Feature of MFI402:

LCD display, Economical price, MFR method, motorized cutting, with micro-printer.


There are two main procedures:

Procedure A (for MFR): This involves manually cutting and weighing the extruded plastic at timed intervals.

Procedure B (for MVR): Instead of weighing, this method tracks how far the piston moves using displacement sensors, giving you volume flow.

Accuracy is everything in these tests. Small changes in temperature, load, or die size can skew the results. That’s why standardized test conditions—like those in ASTM D1238 or ISO 1133—are followed strictly.

Model MFI402 is for only MFR, so deduct the related parts with MVR and reduced the cost. 


Main Features

  • Key feature
  • Test Procedure
  • Standard

Mainframe is desk-top model, with beautiful appearance and stable performance, high accuracy, easy to use.

With high sampling, and high control rate.

With Micro-printer to print test result.

Only remain MFR method to meet many kinds materials, reduce cost to make this model economical price and budgetary project.

Manual and motorized both way cutting sample. 

Approximately 7 grams of the material is loaded into the barrel of the melt flow apparatus, which has been heated to a temperature specified for the material. A weight specified for the material is applied to a plunger and the molten material is forced through the die. A timed extrudate is collected and weighed. Melt flow rate values are calculated in g/10 min.
