Mainly Test Standards:
- GB/t3682-2018: determination of melt flow rate and melt volume flow rate for thermoplastics
- ISO 1133:1997: determination of melt mass flow rate MFR and melt volume flow rate MVR for thermoplastics
- ASTM D1238: ASTM D1238: standard test method for determination of flow rate of thermoplastics melt by extruded plastimeters
Features:
- Multi-stage (2 stage) temperature control mode, 2 groups of platinum resistance sensors, 2 copper heating sleeve separate temperature control, high-precision intelligent PID control, temperature rise slope is adjustable speed.
- The temperature resolution was 0.1℃, the temperature fluctuation within 24 hours was no more than 0.5℃, and the displacement sensor resolution was 0.01mm.
- It has the over temperature protection device.
- Manual automatic cutting, can be arbitrarily set cutting time (0~999), cutting times (0~999)
- The mass method, the volumetric method, or both methods can be used in the test, and the flow rate ratio can be calculated. Both methods start the test when the piston rod moves to a certain position.
- The material preheating seconds countdown of 240 seconds (GB3682) can be set. At the end of the countdown, the weight will be automatically loaded and cut automatically after loading to the specified range. The preheating time of American standard (ASTM) can also be set.
- Built-in multiple plastic material melt index test conditions, convenient for customers at any time access to use, reduce tedious workload, and store the last test conditions and results.
- Built-in mini printer for easy printing of test data.
- High-precision touch screen controller, 7-inch touch screen, can store and print the latest test conditions and data, the test print menu Settings include test time (system default), material name, test conditions (temperature, weight, cutting time interval), test result data.
- RS232 interface or USB interface is reserved to connect to the computer, which can control the operation of the instrument and save the test data to the computer.
- The weight is placed on the bracket of the weight in advance, which can realize electric loading and unloading and reduce manual operation.
