Product Description

The MFI-623 Melt Flow Index Tester is a high-precision instrument designed to measure the melt flow rate (MFR) of thermoplastics, such as polyethylene and polypropylene. This test helps assess polymer viscosity, flow characteristics, and overall quality—making it a crucial tool for plastic manufacturing, compounding units, and quality control laboratories.

At the heart of the device is a PID temperature-controlled extrusion plastometer, which ensures outstanding temperature stability with an accuracy of 0.1°C. This provides consistent thermal conditions for highly repeatable test results.

The system includes a hardened steel cylinder with a precisely controlled internal diameter and length, helically wound heaters, and high-quality thermal insulation for uniform heating. The mild steel piston, designed with an ebonite stud for load isolation, smoothly applies the standard load (2.16 kg) required for accurate melt flow measurement.

By heating the polymer and measuring the rate at which it flows through a standard die under controlled load and temperature, the apparatus delivers essential data used in polymer grading, material selection, and process optimization.
