Melt Flow Index Tester – Accurate Flow Testing for Thermoplastics

 Pacorr introduces a highly advanced and reliable Melt Flow Index Tester, specifically designed to evaluate the melt flow characteristics of thermoplastic materials. As one of the leading manufacturers, suppliers, and exporters of polymer testing instruments, Pacorr offers a robust solution that helps ensure material consistency, quality control, and process optimization across plastic and polymer-based industries.

Understanding the Melt Flow Index (MFI) of polymers is essential for determining how a material will behave during molding or extrusion. Pacorr’s MFI Tester provides unmatched precision, durability, and user-friendly operation, making it the preferred choice among quality-conscious manufacturers and laboratories.

What is a Melt Flow Index Tester?

A Melt Flow Index Tester, also referred to as an MFI Tester or Melt Flow Rate Tester, is a laboratory instrument used to determine the rate at which a polymer melts and flows through a standard die under controlled temperature and pressure. The value is expressed in grams per 10 minutes (g/10min), which indicates how easily the material can be processed in manufacturing environments.

Pacorr’s MFI Tester complies with international standards such as ASTM D1238 and ISO 1133, ensuring accurate and repeatable results that meet global quality norms.

Why Melt Flow Testing is Important

For plastic and polymer manufacturers, understanding the melt flow index is a key factor in ensuring the quality and performance of the end product. Here’s why this test is vital:

  • ✅ Material Selection: Helps in selecting the right polymer grade for different processing techniques like injection molding, blow molding, and extrusion.

  • ✅ Quality Control: Ensures that every batch of material meets flowability specifications.

  • ✅ Process Efficiency: Assists in adjusting temperature and pressure settings during production.

  • ✅ Supplier Validation: Verifies the quality of raw material from various vendors.

Whether you're a manufacturer, supplier, or exporter of plastic products, MFI testing ensures you deliver products that meet performance standards.

  • Standard load weights ranging from 2.16 kg to 21.6 kg.

  • Compact design suitable for laboratories and on-site quality testing.

These features make Pacorr’s MFI Tester ideal for a wide range of industries and testing needs.

Working Principle of Melt Flow Index Tester

The testing process is based on the extrusion of molten plastic through a narrow die under specific conditions. A pre-weighed polymer sample is loaded into the heated barrel. Once it reaches the desired test temperature, a standardized weight is applied through a piston. The molten polymer is then forced through a capillary die, and the extruded material is collected over a fixed time interval.

The melt flow rate (MFR) is then calculated using the weight of the extrudate, expressed in grams per 10 minutes. This value reflects the processability of the material, helping manufacturers adjust their production settings accordingly.

Technical Overview (Descriptive)

Pacorr’s MFI Tester supports a temperature range of ambient to 400°C, ideal for most thermoplastics. The PID-controlled cartridge heaters ensure consistent heat distribution. The device uses stainless steel barrels and dies to resist wear and corrosion. Load weights include 2.16 kg, 3.8 kg, 5 kg, 10 kg, and 21.6 kg, depending on material requirements. The tester also includes a digital timer, manual/motorized cutter, and operates on a 220V AC, 50 Hz power supply.
