Melt Flow Index Tester (KAYJAY/2005/CE) — Manual Model, Test Method A

About Melt Flow Index Tester (KAYJAY/2005/CE) — Manual Model, Test Method A

As per ASTM D 1238 & ISO 1133 (Test Method A - Manual) to check Melt Flow Rate (MFR) of Thermoplastics & Compounds.

The KAYJAY/2005/CE Melt Flow Index Tester is the economical entry-level model in our MFI range, designed especially for small-scale polymer producers, plastic film manufacturers, plastic pipe makers and educational testing laboratories. It works fully as per ASTM D 1238 and ISO 1133 Test Method A — Manual operation.

Despite being an entry-level instrument, the 2005/CE uses the same high-grade microprocessor-based auto-tuned PID controller and digital timer as our higher-end models, ensuring lab-grade accuracy. The operator manually cuts the extrudate at the preset time interval, weighs the sample on a separate balance and calculates Melt Flow Rate (MFR) in grams per 10 minutes.

Melt Flow Index testing is a critical gateway test for almost every polymer industry, and the 2005/CE makes that capability accessible to small businesses without compromising on result accuracy.

Frequently Asked Questions

Is the KAYJAY/2005/CE suitable for production-line quality control?

Yes, but it is best suited for low-to-medium daily testing volumes. For continuous, high-volume production-line quality control, we recommend upgrading to the KAYJAY/2006/AC model with motorised auto-cutting.

These two weights cover the most common ASTM D 1238 test conditions used worldwide — 190°C/2.16 kg for polyethylene and 230°C/2.16 kg for polypropylene, plus the 5 kg load for high-density polymers. Additional weights (1.2 kg, 3.8 kg, and 21.6 kg) can be supplied on request at extra cost.

When the operator follows the standard procedure carefully, the accuracy of Test Method A manual cutting remains fully within ASTM D 1238 tolerances. The built-in buzzer alert helps ensure sample cutting at the exact preset interval.

No. The manual-cut and auto-cut variants use different mechanical assemblies. If there is any possibility of future unattended testing requirements, we recommend selecting the auto-cut KAYJAY/2006/AC model from the outset.

Yes. Every KAYJAY/2005/CE Melt Flow Index Tester is supplied with a factory calibration certificate. On-site recalibration services are also available through our service network.
