Product Description
This is a high-precision fully automatic melt flow index tester.
It is used to measure the MFR/MVR value of the melt flow rate of various plastics and resins through a standard die every 10 minutes when they pass through a certain temperature and load in the viscous flow state.
It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, and nylon with higher melting temperatures.
It is also suitable for polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyethylene Testing of plastics with lower melting temperatures such as formaldehyde (POM) and polycarbonate (PC) resin is widely used in plastic production, plastic products, petrochemical and other industries as well as related universities, scientific research units and commodity inspection departments.

Product advantage:
-1.Multi-stage (2-stage) temperature control method, 2 sets of platinum resistance sensors, 2 heating jackets for independent temperature control, high-precision intelligent PID control, the heating slope or heating speed is adjustable
-2.The temperature resolution is 0.1℃, the temperature uniformity is 0.2℃, the temperature fluctuation within 24 hours does not exceed 0.5℃, and the displacement sensor resolution is 0.001mm.
-3.Temperature over-temperature protection device
Integrated manual and automatic cutting, cutting time (0~999) and cutting times (0~999) can be set arbitrarily
-4.When testing, you can choose the mass method, the volume method, or both testing methods at the same time, and the flow rate ratio can be calculated. Both methods start testing when the piston rod moves to a certain position.
-5.It has a built-in temperature stabilization alarm, and adds a 240-second (GB3682 stipulated) material preheating second countdown. After the countdown is over, a prompt sound will sound, and the preheating time such as American Standard (ASTM) can also be set.
-6.A variety of plastic material melt index test conditions are built-in, which is convenient for customers to call up and use at any time, reducing tedious workload, and storing the last test conditions and results.
-7.Built-in micro printer for easy printing of test data
-8.High-precision touch screen controller, 7-inch touch screen, can store and print recent test conditions and data. The settings of the test print menu include test time (system default), operator, material name, test method, test conditions (temperature, weight) Weight, cutting time interval), test result data, test result artificial judgment OK or NG, etc.
-9.The RS232 interface or USB interface is reserved to connect to the computer, and the instrument operation can be controlled through the computer and the test data can be transmitted and saved to the computer.
-10.The weight can be loaded manually or the ball screw can be driven by a stepper motor to automatically control the rise or fall of the top-loaded weight.
