DF82.300 New generation MFR testing machine

Category:

Features

  • Goodappearance, stable and reliable performance;
  • The furnace tube is made of purple copper, with low resistance and good thermal induction effect. Aluminum silicate cotton is used as insulation cotton between the furnace tube and the furnace chamber, which has a significant insulation effect;
  • The inner wall of the barrel and the head of the piston rod are treated with Nitriding technology, which has high hardness and wear resistance;
  • The feeding port adopts a seamless design, and the piston rod does not require a guide ring, resulting in smoother material pressing and less waste accumulation at the feeding port;
  • The baffle of outlet port at the bottom of the furnace is designed to be semi closed, which facilitates the closure and removal of the outlet, and is more conducive to testing specimens with high melt index;
  • The displacement sensor adopts a high-precision encoder, with a displacement acquisition accuracy of ± 0.005mm;
  • The automatic cutting device consists of a drive circuit, an electric motor, and blades. Installed at the bottom of the material barrel, it has a compact size and flexible movement. It can be operated with jog, automatic cutting, adjustable force, and excellent cutting effect;
  • The controller is a microcomputer controller specially developed by SINOTEST, which adopts a 7-inch high-definition touch screen display control, simple operation, and stable performance;

The weights are independent weights, convenient for viewing and taking, and easy to use.

Application fields

System setting

  • The heating time and feeding time can be modified, making the experiment more flexible and convenient;

  • It can perform multi-point temperature correction, making the temperature more accurate;

  • ENG software language setting;

 

Volume method for testing

 

  • The volume method can perform multi segment cutting, calculate the mean and values of each segment, and improve experimental efficiency;

  • specimencutting length: The appropriate stroke can be manually input based on the melting characteristics of the specimen, making the test plan more versatile;
  • Shielding function: For specimens with high melt index, shielding can be selected to ensure more accurate time collection;
  • The test time can be set and is no longer fixed at a constant value

 

Mass method for testing

  • The mass method has calculation function, and the result can be obtained by filling in the mass;
  • The experimental steps can be skipped according to different requirements.

Data storage and printing

Both the Mass method and the Volume method can be used for data storage, and can be repeatedly queried and printed, as shown in the following figure:
