Product Overview
The GT-MFI-450D Melt Flow Indexer is a cutting-edge tabletop instrument designed to measure the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastic materials, adhering strictly to ISO 1133, ASTM D1238, and GB/T 3682 standards. This versatile device caters to a wide range of thermoplastic forms, including granules, film strips, and pellets, making it an essential tool for quality control in polymer manufacturing, raw material testing, and research laboratories.
Unlike conventional flow testers, this model combines affordability with high precision, enabling accurate comparisons between filled and unfilled thermoplastics, as well as materials with varying filler contents. Its ability to calculate melt density (when melt density at test conditions is known) adds significant value for material characterization, ensuring consistent product quality across production batches. Whether used in small-scale workshops or large industrial facilities, the GT-MFI-450D delivers reliable data to support informed decision-making in material selection and process optimization.

Design
Control System
The GT-MFI-450D features a dual-control design, integrating a 7-inch color touch screen with PC-based software for seamless operation. The touch screen provides intuitive access to real-time data, while the PC software offers advanced functionalities such as parameter configuration, test data storage, and result export in multiple formats (Excel, PDF). This hybrid control system ensures flexibility for both on-site operators and remote monitoring needs.
Precision Engineering
Equipped with a high-sensitivity displacement sensor, the instrument achieves MVR displacement accuracy of 0.02mm, ensuring precise volume flow measurements. The built-in automatic cutting mechanism triggers at preset intervals with a timing error of ±0.1 seconds, eliminating human error in sample collection. Rapid heating elements enable the device to reach set temperatures quickly, with minimal overshoot, and maintain temperature control accuracy of ≤ 0.2℃ for consistent test conditions.
Safety & Durability
To prevent unauthorized adjustments, critical operations (e.g., calibration, parameter reset) require password verification. The instrument also includes over-temperature protection, audio alerts for temperature stability, and automatic shutdown safeguards, ensuring safe operation in industrial environments. Its robust stainless-steel cylinder and piston rod resist corrosion from molten plastics, extending service life even with frequent use.
