Melt Flow Index Tester For Plastic Material Quality Control

The Melt Flow Index Tester is a precision testing instrument designed to measure the melt mass-flow rate (MFR) of thermoplastic materials under specified temperature and load conditions. It helps manufacturers evaluate material flow characteristics, maintain consistent product quality, and select suitable raw materials for plastic processing applications.

Featuring a temperature range from room temperature to 450°C, the Melt Flow Indexer is suitable for testing a wide variety of thermoplastics, including polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, polycarbonate (PC), polyoxymethylene (POM), nylon, and other engineering plastics. Its broad testing capability makes it a valuable tool for plastic manufacturers, petrochemical laboratories, research institutions, and quality inspection departments.

The digital melt flow index tester is equipped with a high-resolution color LCD display, a dual temperature control system, and dual temperature sensors to support accurate temperature monitoring. Temperature fluctuation is specified at ±0.2°C, while temperature uniformity is ±1°C. These features help maintain controlled testing conditions for reliable material evaluation.

To improve testing efficiency, the instrument integrates manual and automatic cutting functions. It can automatically calculate test results and print reports through its built-in micro printer, reducing manual calculation and simplifying routine laboratory operations. Eight test load levels provide flexibility for different material testing requirements.

Designed for practical laboratory use, the plastic melt flow index testing machine supports standardized testing procedures based on the specifications listed for GB/T 3682, ISO 1133, and ASTM D1238. Users should confirm the applicable edition and test method before conducting compliance testing.

For plastic processors, material suppliers, and testing laboratories, the Melt Flow Index Tester provides an efficient solution for evaluating thermoplastic flow properties, supporting incoming material inspection, production quality control, and research and development.
