Computerized Melt Flow Index Tester (MFR & MVR) – Method A, B & C | PLC Controlled Touch Screen

 In the modern plastics and polymer industry, product quality and processing efficiency depend heavily on the consistency of raw materials. One of the most important tests used to evaluate thermoplastic materials is the Melt Flow Index (MFI) test, which provides critical information about a polymer’s flow behavior under controlled conditions. To meet the growing demand for accuracy, automation, and compliance with international standards, Pacorr offers a Computerized Melt Flow Index Tester (MFR & MVR) with PLC-controlled operation and a touch screen interface, supporting Method A, B, and C.

Importance of Melt Flow Index Testing

Melt Flow Index testing measures how easily a thermoplastic material flows when melted under a specified temperature and load. This flow behavior directly affects how the material performs during processing methods such as injection molding, extrusion, and blow molding. The results of the test are expressed in two standard formats:

  • Melt Flow Rate (MFR): The mass of polymer that flows through a standard die in a fixed period.

  • Melt Volume Rate (MVR): The volume of molten polymer that flows over time.

Accurate MFI values help manufacturers select suitable materials, maintain batch-to-batch consistency, reduce production defects, and ensure compliance with quality standards. Even small variations in melt flow can significantly impact the final product’s strength, appearance, and performance.

Advanced Computerized and PLC-Controlled Design

Pacorr’s Melt Flow Index Tester is designed with a fully computerized system integrated with PLC control, ensuring precise regulation of all critical testing parameters. Temperature stability, applied load, and timing accuracy are maintained throughout the test, delivering reliable and repeatable results.

The touch screen interface provides a user-friendly operating experience. Operators can easily set test parameters, select the required method, monitor the test in real time, and view results instantly. This intuitive design minimizes manual intervention, reduces the chance of operator error, and shortens training time, making the system suitable for both laboratory and production environments.

Supports Method A, B & C (MFR and MVR)

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

  • Method A: A manual cut-off method commonly used for determining Melt Flow Rate in routine quality control applications.

  • Method B: An automatic method that measures piston displacement to calculate Melt Volume Rate, improving accuracy and efficiency.

  • Method C: A fully automated method that enhances precision and consistency while minimizing operator involvement.

By supporting all three methods, Pacorr’s tester allows users to comply with multiple testing standards using a single, versatile instrument.

High Accuracy and Consistent Results

Accurate temperature control is essential for valid MFI testing. Pacorr’s Melt Flow Index Tester features a high-precision heating system that maintains uniform temperature throughout the test barrel. Stable load application and automated measurement further ensure consistent and reproducible results across different materials and test conditions.

Automatic calculation and digital display of MFR and MVR values eliminate the need for manual calculations, saving time and improving overall efficiency in quality control and research laboratories.

Applications Across Industries

The Computerized Melt Flow Index Tester from Pacorr is widely used in:

  • Plastic and polymer manufacturing units

  • 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 Operation

Built for long-term use, the instrument features a robust construction capable of withstanding continuous operation in industrial environments. Its ergonomic design, combined with an easy-to-navigate touch screen interface, ensures smooth workflow, minimal maintenance, and long service life, making it a cost-effective investment for organizations focused on quality and reliability.
