Function summary

Automatic melt flow rate tester (also known as melt index meter) is a special instrument for measuring the melt flow rate of thermoplastics under certain conditions。

The melt flow rate (melt index) of thermoplastics refers to the mass or melt volume of the melt through the standard die every 10 minutes at a certain temperature and load, expressed by the MFR (MI) or MVR value。The test is mainly used for the quality inspection and storage inspection of raw materials and products of thermoplastics and chemical fibers。

Machine height automation，Integrated press, lifting weights and cleaning processes;Through the clasp on the device，Can accurately control each pressing process;The equipment is in the process of testing，The loading and lifting of weights are completed automatically without manual intervention;After the test is completed, it is equipped with special cleaning components，Barrel cleaning is done at the touch of a button。
