The Melt Flow Index Tester, also called an MFI Tester or Melt Flow Indexer, measures the melt flow rate of thermoplastic materials under specified temperature and load conditions. The test determines how much molten polymer passes through a standard die in a given period.
Melt flow testing is widely used for quality control, material comparison, process control, and thermoplastic material testing. The melt flow rate is commonly reported in grams per 10 minutes (g/10 min).

The Melt Flow Index Tester is designed to measure the melt flow rate of thermoplastic polymers under controlled test conditions. The sample is heated to a specified temperature and subjected to a defined load. The molten material then flows through a standardized die, and the extruded material is measured to determine the melt flow rate.
The machine features a microprocessor-based PID temperature controller with a temperature range from ambient to 400°C. Its 0.1°C resolution enables precise temperature control during testing.
The tester is designed to meet commonly used testing standards, including:
The digital LED display provides clear readings during the test.
The MFI Tester measures the flow of a thermoplastic material through a standardized die under controlled temperature and load conditions.
The test follows these basic steps:
The test result provides a standardized measure of the material's flow behavior under the selected test conditions. Manufacturers can use this result for incoming material inspection, quality control, batch comparison, and process monitoring.
The MFI Tester is used for testing thermoplastic materials in applications such as:
Consistent Melt Flow Testing
The tester maintains controlled temperature and load conditions to provide repeatable melt flow measurements.
Quality Control
MFI testing helps manufacturers compare material batches and identify changes in melt flow behavior before or during production.
Precise Temperature Control
The microprocessor-based PID controller provides controlled heating with a temperature resolution of 0.1°C.
Standardized Testing
The tester is designed for testing according to standards such as ASTM D1238, IS 2267, IS 2530, and IS 10810.
Suitable for Different Thermoplastic Materials
The MFI Tester can be used to evaluate the flow characteristics of different thermoplastic polymers, plastics, and resins under specified test conditions.
Digital Display
The LED digital display provides clear readings for temperature and test operation.
Testronix Melt Flow Index Testers are designed to provide consistent and precise measurement of melt flow properties for laboratory and quality-control applications.

The Melt Flow Index Tester is designed for testing in accordance with commonly used standards, including:
The applicable standard and test conditions should be selected according to the material being tested and the required testing method.
A Melt Flow Index Tester measures the melt flow rate of thermoplastic materials under a specified temperature and load. The molten material is forced through a standardized die, and the amount of material extruded over a specified time is measured. The result is generally expressed in grams per 10 minutes (g/10 min) and is used for material quality control, batch comparison, and process monitoring.
An MFI Tester is used to determine the melt flow behavior of thermoplastic materials. Manufacturers and laboratories use MFI testing to compare material batches, monitor raw material quality, and evaluate thermoplastic materials before or during production. The tester can be used according to standards such as ASTM D1238, IS 2267, IS 2530, and IS 10810, depending on the applicable test method.
A typical MFI test involves placing a specified quantity of thermoplastic material into the heated barrel of the tester. The material is heated to the required test temperature and held for the specified preheating period. A defined load is then applied to the piston. The load forces the molten material through the standard die. The extruded material is collected and measured to determine the melt flow rate in grams per 10 minutes. For example, commonly used test conditions can include 190°C with a 2.16 kg load for certain polyethylene materials and 230°C with a 2.16 kg load for certain polypropylene materials. The exact temperature, load, sample quantity, and test procedure depend on the applicable material specification and testing standard.
The price of a Melt Flow Index Tester in India typically ranges from INR 50,000 to INR 2,00,000, depending on the model, configuration, test loads, features, and accessories.
