Computerized Melt Flow Index Tester (Method A)

A PC-interfaced Method A Melt Flow Index Tester with motorised cutting, automatic weighing and software-based result calculation, storage, averaging and statistical analysis — for labs that need traceable, report-ready data.

  • PC-interfaced with dedicated MFI software
  • Motorised cutting and automatic weighing
  • Automatic MFR calculation, storage and statistics
  • Auto-tuned PID: ambient–400 °C, ±0.1 °C accuracy
Made in IndiaISO 9001:2015CE CertifiedExported to 60+ countries
Overview

Traceable, report-ready MFR data

The Computerized (Method A) model connects the MFI tester to a PC: motorised cutting and automatic weighing feed directly into software that calculates MFR, stores every result, averages replicates and runs statistical analysis. It removes manual weighing and record-keeping, giving traceable, audit-ready data.

It suits laboratories with reporting and traceability requirements — certification labs, larger processors and R&D. Manufactured in Mumbai, CE marked and supplied with a calibration certificate.

How the test works

Step by step

  1. Set temperature & loadSelect the ASTM/ISO test temperature and standard weight for your polymer and let the barrel stabilise.
  2. Charge the barrelLoad the pre-weighed polymer, compact it and preheat for the specified time.
  3. Apply the weightPlace the load; the molten polymer extrudes through the standard orifice.
  4. Cut & measureMethod A — cut the extrudate at fixed intervals and weigh each cut. Method B — a displacement sensor tracks piston travel for MVR & melt density.
  5. Calculate the resultMFR (g/10 min), MVR (cc/10 min) and melt density are computed, and on computerized models stored, averaged and reported.

Applications

Where it's used

Raw material QCVerify incoming polymer granules against supplier specification.
Batch consistencyCheck batch-to-batch consistency during compounding.
Recycled plasticsTest regrind and recyclate before it enters production.
Grade identificationIdentify the grade of unknown thermoplastics.
Process controlInjection, blow moulding, film and pipe extrusion.
R&DEvaluate new polymer formulations and additives.
Standards

Standards covered

Every MFI tester complies with ASTM D1238 and ISO 1133, plus IS 2530 and IS 10810 for Indian standards, and is supplied with a traceable calibration certificate. Method A measures Melt Flow Rate (MFR) by cutting and weighing the extrudate; Method B adds Melt Volume Rate (MVR) and melt density via a piston-travel sensor.

FAQ

Frequently asked questions

What does the software add over the auto-cut model?
Automatic weighing, direct MFR calculation, result storage, averaging of replicates and statistical analysis — producing traceable, report-ready data without manual record-keeping.
Does it still do motorised cutting?
Yes — it includes motorised cutting and adds automatic weighing and PC-based calculation on top.
Is it good for certification labs?
Yes — the traceability, storage and statistics suit labs with audit and reporting requirements.
Which method does it run?
ASTM D1238 Method A (MFR). For MVR and melt density as well, choose the Computerized Method A & B model.
