The Melt Flow Index machine is a testing instrument used by polymer product manufacturers. It helps analyze the flow properties of thermoplastic polymers in a melted state. It helps define the polymer's viscosity and is often used as a quality control tool by manufacturers of thermoplastic material. The instrument works on user-defined automated methods customized to test the sample under various temperatures.
Testing the plastic raw materials before manufacturing products is a mandatory protocol. It helps manufacturers compare the performance of different polymer grades enabling them to track changes in polymer properties over time. Unlike metals, the polymer properties depend on temperature, humidity, age, etc. The test results can help make insightful decisions regarding the material and its widespread application.
How Does Melt Flow Index Tester Work?
The Melt flow index test machine heats and compresses the polymer sample under precisely controlled temperatures. The process involves heating resin granules to a specific temperature. The molten resin flows through a narrow aperture towards the other end of the instrument and is cut into small pieces by a sample cutter for a specific time interval. The weight of the polymer is recorded using a digital weighing scale. The recorded value is known as the Melt Flow Index.
Polymers are made of a long chain of smaller monomer molecules. Polymers with short unbranched chains have low melt viscosity, while the more complex branched chains exhibit high melt viscosity. The melt flow index test gives an idea of the physical properties and durability of the finished product.
What Is The Use Of An MFI Tester?
- The MFI test instrument empowers manufacturers to check if their products meet specific viscosity standards.
- Researchers and engineers often use the Melt flow index test machine to understand the behavior of thermoplastic polymers under various conditions during the testing phase. The test results can be used to optimize processing parameters and improve the final product quality.
- The tester can track changes in polymer properties over time, such as changes due to
- aging or exposure to specific elements or conditions.
How To Choose The Best MFI Tester For Your Manufacturing Unit
- Advanced Features: Opt for an advanced version of the flow index testing equipment. It may be costly compared to the manual versions, but it can save you lots of effort and valuable time in the long run, which can be utilized for various productive purposes.
- Temperature range: Make sure that the tester can accurately measure the MFI of your plastics at the specific temperature range to test their durability. There are various microprocessor-based controller MFI that work efficiently when subjected to testing.
- Weight range: Ensure that the tester can adapt to the weight range of your polymer samples. A tester with a digital weighing balance and auto-weighing of molten sample feature can save you lots of time. Many advanced testers in the market are equipped with an MFR calculator that frees the user from tedious manual tasks such as cutting, weighing, or evaluating results.
Ease of use: Consider the functionality of the tester. Automatic data logging or computer connectivity makes the instrument more convenient.
Bottom Line
Innovation has expanded the horizons in every sphere of polymer application. Plastics have become a go-to option widely used to make toys, quality medical equipment, food packaging, carry bags, etc. The polymer grades have drastically improved over time to enhance the durability and strength of the final products. Look for a reputable brand like Pacorr that is known for producing high-quality MFI testers to test the material before you move ahead with the production. The high-quality polymer can help the manufacturer produce an affordable range of highly consumable products. However, low-quality plastics are bound to fail in the marketplace and will lead to drastic loss and waste of valuable time, money & resources. Hence it's extremely important to test the product's durability before launch to ensure successful sales and high returns.
