Apply These Six Easy Steps to Level Melt Flow Index Tester

The MFI rate or melt flow rate is one of the most important properties of polymers that needed to be tested to measure the flow of a polymer when melted. Thus, to test the melt flow rate of polymers, you can easily make use of the melt flow index tester from Presto. This amazing lab testing equipment has been designed to test the flow properties of molten plastics as well as resins. The determination of the melt flow index of plastic materials is an important parameter in the evaluation of its quality. Thus, with the use of the Presto Melt Flow Index Tester, you can easily test the quality of this lab testing equipments.

Now, let us discuss brief information about the melt flow index tester and how you can easily level this testing machine. So, let us get started.

Measure the resistance of the flow of materials with MFI tester

The melt flow index tester or MFI tester is one of the accurate testing equipment that is commonly used in the plastic and polymer industry to measure the resistance to the flow of materials. This is one of the quality testing instruments that help in analyzing the different attributes of melt flow rate and viscosity under a certain load.

Whenever you are ready to conduct the test with the help of this lab testing instrument then you need to take some precautions to conduct the test effectively. The first and foremost thing that you need to take care of is to select the test conditions according to standards. The temperature of the barrel must be set in accordance with the instructions given in the instruction manual. A visual analysis of the orifice should be done to see if there will be any scratches or damage present in the orifice or not. You can read about more precautions for the MFI test here.

The main purpose of conducting the test with the help of this lab testing equipment is to improve the quality of the product. This lab testing instrument has been designed with several features that can extrude the flow rate of molten resins utilizing the advanced setup load.

Six easy steps to level melt flow index tester

Leveling the machine is a very important process while conducting the test. Thus, we have come up with some easy-to-follow steps that will help you to level the machine with ease.

  • For checking the leveling of the machine, use the plumb line provided with the machine.
  • Take out the orifice die from the machine and insert the plumb line inside the barrel.
  • Now check the perpendicularity of the plumb line related to the ground.
  • If the plumb line is perfectly perpendicular to the ground, this means the machine is perfectly leveled.
  • If the plumb line is slightly deflected from the perpendicular direction, this means the machine needs leveling.
  • Level the machine by aligning the footrests.

In this way, you can easily level the machine and perform the test accurately. You can also get information about Compound Resin Testing Instruments.
