Computerized Melt Flow Index Tester (MFR & MVR) – Method A, B & C

In the polymer and plastics industry, precise control over material properties is essential for achieving consistent processing performance and high-quality end products. One of the most critical tests used to evaluate thermoplastic materials is Melt Flow Index (MFI) testing, which provides valuable insight into a polymer’s flow behavior under defined temperature and load conditions. To meet modern industry demands for accuracy, automation, and reliability, Pacorr offers a Computerized Melt Flow Index Tester (MFR & MVR) equipped with PLC-controlled operation and a touch screen interface, supporting Method A, B, and C.

Significance of Melt Flow Index Testing

Melt Flow Index testing helps determine how easily a thermoplastic material flows when molten. This flow behavior directly affects processing techniques such as injection molding, extrusion, and blow molding. By evaluating melt flow characteristics, manufacturers can ensure material consistency, optimize processing parameters, and maintain uniform product quality.

MFI test results are expressed in two standard formats:

• Melt Flow Rate (MFR): Measures the mass of polymer flowing through a standard die in a specified time.
• Melt Volume Rate (MVR): Measures the volume of molten polymer flowing per unit time.

Accurate MFR and MVR values are essential for quality control, raw material selection, and compliance with international testing standards.

Advanced Computerized and PLC-Controlled Operation

Pacorr’s Melt Flow Index Tester is designed with a fully computerized system integrated with PLC control, ensuring precise regulation of critical testing parameters such as temperature stability, applied load, and timing accuracy. This level of automation reduces operator dependency and minimizes the risk of manual errors, resulting in highly repeatable and reliable test results.

The touch screen interface enhances usability by allowing operators to easily set test conditions, select the appropriate method, monitor test progress in real time, and view results instantly. This intuitive design improves efficiency and makes the instrument suitable for both laboratory and production environments.

Method A, B & C Compatibility

One of the major advantages of this Melt Flow Index Tester is its ability to perform tests using Method A, B, and C, offering flexibility for different testing needs:

• Method A: A manual cut-off method commonly used for routine Melt Flow Rate determination.
• Method B: An automatic method that calculates Melt Volume Rate through piston displacement measurement, providing improved accuracy.
• Method C: A fully automated method that enhances precision and repeatability while minimizing operator involvement.

Supporting all three methods allows users to meet multiple testing requirements using a single, versatile instrument.

Accuracy and Consistent Performance

Temperature control plays a vital role in obtaining accurate MFI results. Pacorr’s tester features a high-precision heating system that ensures uniform temperature distribution throughout the test barrel. Combined with stable load application and automated measurement, the system delivers consistent and reproducible results across different materials and test conditions.

Automatic calculation and digital display of MFR and MVR values eliminate manual calculations, saving time and reducing the likelihood of errors in busy testing environments.

Applications Across Industries

The Computerized Melt Flow Index Tester is widely used in:

• Plastic and polymer manufacturing plants
• Quality control and quality assurance laboratories
• Research and development centers
• Educational and material testing institutions

It is suitable for testing a wide range of thermoplastic materials, including polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, and other commonly used polymers.

Durable Construction and User-Friendly Design

Built for long-term reliability, the instrument features a robust construction capable of withstanding continuous use in industrial environments. Its ergonomic layout and user-friendly touch screen interface ensure smooth operation, minimal maintenance, and long service life, making it a cost-effective investment for quality-driven organizations.
