The Melt Flow Index Tester or MFI Tester helps in testing the flow properties of plastics. The melt flow indexer machine is used to calculate the melt flow of thermoplastic polymers. The physical and chemical properties of any material can be analyzed on the basis of the melt flow rate. The melt flow rate is an important measure in the PET and polymer industry.

The melt flow index test has to be conducted by manufacturers’ prior production. A digital display is another feature which helps in accurate measurement of results. The melt flow index (MFI) consists of a microprocessor based PID temperature controller which a range of 0 degrees to 400 degree Celsius. It has very high precision with a resolution of 0.1 degree Celsius. The equipment adheres to all industry standards (ASTM D 1238, IS 2267, IS-2530, IS 10810).
The melt flow index (MFI) tester operates on a straightforward principle to measure the flow properties of thermoplastic materials. It involves heating a sample of the material to a specified temperature until it melts, then applying a constant pressure to extrude the molten material through a standardized die.
The rate at which the material flows through the die, measured in grams per 10 minutes, is known as the melt flow rate (MFR). This measurement is indicative of the material's viscosity and flow behaviour under specific conditions.
By controlling the temperature, pressure, and dimensions of the die, the MFI tester provides valuable insights into the rheological properties of the material, aiding in quality control, process optimization, and material selection in various industries.
Testing MFI is essential for thermoplastic materials. It helps with understanding how they flow. The flow rate shows how thick the material is and how it moves. This is vital for making sure products are always consistent in the quality.
Also, MFI testers are very consistent and can provide dependable and precise measurements. This consistency is important for checking quality, helping manufacturers spot any differences in material properties and fix them quickly.
Also, MFI testing is a non-destructive method for material being tested. This makes it good for regular quality checks without harming the samples. It's safe and reliable. Testronix Melt Flow index tester offers precise and accurate measurements of melt flow properties of the samples with ease.
Also, MFI testing is flexible and can be used with many types of thermoplastic materials, like plastics, resins, and mixtures. This flexibility makes it a useful tool for scientists and makers working with different materials in many industries.

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.
