This tester is used by the manufacturer before starting its mass production as the machine is showing results on the digital display. Melt flow index tester is used in the plastic and polymer industry. This instrument helps to measure the resistance of plastic material which melts at a particular temperature. From the test, you can easily calculate under which pressure plastic will melt under load.

The test specimen is put into the heated barrel then pressed through a piston and a load is applied to the material. When plastic granules at a certain temperature melt. Soften weight over the piston. The viscosity of the material was high at the beginning but it decreased after a few seconds due to piston pressure. If the rate of melting is high then viscosity will be low. That helps check the quality of plastic that should be used in further manufacturing.

Functioning of the Melt Flow Index Tester

This instrument is based on the principle that it helps in measuring the properties of the flow of plastic granules and thermoplastic. First set the temperature in the machine it can according to the sample property when the temperature set shows the machine is ready to take plastic granules. Now granules are put into a machine with a spoon.

A standardized dice is hung on the side of the machine through these dice pressure is exerted on granules at a specific temperature and the viscosity of melt granules measurement of this viscosity shown in the machine display and measured in 10 grams per minute is called melt flow rate ( MFR). Then wire forms of granules come out from machines that show the quality of the material and whether it should be used for manufacturing or further purposes.

Benefits of a Melt Flow Index Tester

• When thermoplastic material is tested under a machine the flow rate and viscosity rate of plastic are checked properly and assurance of that is useful for making such a product which is useful for many purposes in industry.
• This tester provides measurements exactly consistent and depends upon the quality of the product. When any item goes under test then everything is checked properly that is why this method is non-destructive. It shows results without harm to the sample so it is a safe and precise method.
• Various types of thermostatic are used under this method like resins, plastic, and various mixtures. It is a scientifically approved method before the application of the machine is fully tested in the laboratory by experts. Who checks it under different temperatures and conditions which checks the quality of the machine.
• If the melt flow of the product is high then the viscosity will be low if the resin flow rate is showing low then the viscosity is high. If the rate of flow of material is low then viscosity shows higher in state. After that material standard was checked within temperature. Through a melt flow index tester it is easy to judge the melting point.
• The melt flow index tester manufacturer provided standardized accessories with machines like a funnel, spoon, spinner, piston, orifice, charger, mirror, cleaner for barrel, etc. Everything is available with the machine. Various melt flow index tester suppliers are available in the market but we are very loyal to our work. We have our machine over every platform but online availability all over India.
• The melt flow index tester price is not high, it is affordable in range. The price of the machine fits into your pocket because the quality and standard of the machine shows it should be a higher price but due to demand for the product it is at an affordable price.

Features of Melt Flow Index Tester

• This model is a touch screen where the user can operate through touch and temperature set according to granule type. When granules of plastic apply force then it is easy to operate in a machine.
• Graphical representation of the result displayed on the screen and graph will be temperature and time. When the temperature is low then it reaches up to the 200 range and above the time taken to melt is calculated.
• Test data can be stored through USB in the machine USB port is available for every bit of data stored because when material melts then it will come out from the machine in the form of wire which shows it is good quality plastic.
• The finish of the machine has an anti rust surface so the design is elegant in look and every equipment which is used in the machine is duly tested. That is why when plastic is in a melting state the temperature is set at a particular degree which is suitable for it.
